Questions related to Conceptual Design
I am in the preliminary design phase of a heavy-lift octocopter. Is there a systematic approach to selecting the proper propeller, motor, and battery for the given configuration provided that the frame size is still variable, the required payload weight is W and the endurance is T minutes?
All of the above parameters are coupled so I am guessing this will be an interactive solution. Any suggestions?
Thank you in advance for your advice and guidance,
I recently came along the "Lego Serious Play" Method and I wonder if anyone uses this method for team building or conceptualizing/ designing new visions for a team in there research infrastructure? Or does anyone even uses this method for their lectures?
I am conducting research on portable oil skimmers, I have used QFD to obtain the technical specifications from the customer's requirements. I have 3 conceptual designs now and I have to choose the best design via the AHP analaysis. However, I am very confused about how to set the weightage of each criteria.
My criteria are:
hi there, am having a electrical vehical design class and i dont know anithing about electric motors .am asked to do a calculations of a a conceptual design of an electric motor and battery for an electric pickup truck and i dont even know where to begin.i tried looking for semilar designs but every design i have seen ether have diffrant resuolts in another place or have missing info.
it would realy help if you could give me just the first step so i can track it or may be an asstimati of the sizing of the motor that i can work with, or like preferd power , coefficince and torque in such vehicle
Researchers experiment with individual and group of designers. In 'engineering design' what are pros and cons (in general) for doing experiment with two designers in a group? By engineering design, I mean a design problem based on mechanical, industrial design etc. By solution, I mean concept generation.
Is it true that a theoretical framework must only consist variables with similar unit of analysis (UoA)? Hence, having variables with different UoA is regarded as wrong approach. For instance, having variables such as organisational performance, human resource management strength and employee engagement in a framework are not acceptable, as it comprise individual and organisational level UoA in a framework. I just found this out from a conference I have attended recently.
I'm looking for software (preferably free!) to use to help me draw good-looking conceptual diagrams for publication. I typically default to Word or PowerPoint but their drawing tools don't offer the kind of functionality and professional look I've seen in some publications.
By 'conceptual diagram' I'm referring to something between a mind map and flow chart. Think about the kinds of diagrams people use to explain the structure of a thesis, or to model an information flow, or to present a conceptual framework...
Can someone please explain what is A-R-A model in short. The Wikipedia information is deficient. It would be great to discuss applications and how one can apply this model in the industry.
- Would this be a topic that is too broad for a research study?
- What conceptual design would work best? Phenomenological or ethnography?
- When you picture a "flat organization" what comes to mind?
Does the perception of AI progression cause a lack of digital congruence, "thus" intensifying fear of risk within flat organizations?
Thank you for your opinions.
I am in process of writing my first conceptual paper, need your help in identifying the key ingredients to write a conceptual paper where no empirical data OR case study is available.
The development of complex technical objects is a multidisciplinary process. Usually development is accompanied by the requirement to satisfy a number of criteria, i.e. it is a process of multi-criteria optimization. Among the criteria there are a number of qualitative requirements. In addition, when defining a number of object parameters, there may be no clear rules, recommendations and methodologies. The possibility of applying fuzzy methods at this stage is connected with this. This raises my question about articles or books in connection with this problem. Please do not write about the application of fuzzy logic for the development of control systems, controllers, etc. This is all well known. Thank you!
We are planning riyadh city as water sensitive urban city. We have developed urban water balance model. How we can get help in applying your model?
I am not sure whether my indirect effects (dashed arrows) are displayed correctly, as it points from the independent variable directly to the dependent and not through the mediator. There are my hypotheses in the attached picture, just for better understanding.
I am implementing design of experiment ,full factorial ,however after analyzing ,there is no sign of factor for predicting model. Actually software(design expert) dose not consider proposed factor for building model.
How can I consider my factors for proposed model in design expert?
Methods based on functional decomposition and morphology belong to the so called systematic design methodology. They are widely taught in accademia, but their diffusion in industry has not reached the same success. Some hypothesis have been formulated by literature, but it is still not possible to identify concrete reasons.
What do you think about that?
I am doing research on aircraft conceptual design and aerodynamic optimization. it is very time consuming to generate meshes for complex geometries. i want to apply the mesh free CFD method to the optimization, such as smoothed particle hydrodynamics (SPH) method. could anybody suggest me some articles on mesh free CFD method? progress in this field, advantages and disadvantages of mesh free method?
- I want to know specifically of problems in a tabloid chair for left-handed users and I want to know what are the solutions that have been done to overcome this problem for the tabloid chair for those left-handed users. The new design of tabloid chair for left-handed
The question (obviously) is in two parts:
Firstly, drawing on the theories around design thinking, in particular within the logical reasoning framework (deduction, induction, abduction) expounded by Nigel Cross, Kees Dorst and N.F.M. Roozenburg), what activities would be carried out by a designer which facilitate creative design and problem solving? What actions and graphic tools (mapping, sketching, diagramming and modelling) would this entail?
Secondly, can these activities be organised in such a way to formulate a method which can be applied in multiple design situations?
If so, how does it work?
I'm currently doing research regarding architectural atmospheres which I'm focusing on light where I found this quite interesting after I read a couple of articles about "Church of Light" designed by Tadao Ando, where he uses light to increase the occupants' awareness/feeling of the spiritual and secular within themselves.
I'm planning to dig deeper into this topic.
I have been doing extensive research on the writings of Nigel Cross, Kees Dorst and N Roozenburg, who indicate that abductive reasoning is at the core of the creative design process.
Diego Fullaondo also supports this assertion in his Deakin University Lecture "Elementary Dr Watson"
How can abudctive reasoning be practically applied in the design process?
In conceptual design phase dead load, live load ,earthquake load, and wind load are the must important factors to fix a initial size of column and shear wall, In my research work i want to develop a generalization network that could find the most appropriate size of column, thickness of shear wall,
Now i have a question to those experienced engineer , which factors like seismic zone,wind categories, live load, dead load, strength of concrete, strength of steel reinforcement, are the most effecting factors to choose the initial size of these components??
Engineers often like to use "best practices" (data, information, knowledge, wisdom) during product development. Some of the data/information come from their experiences working on the job. Others (best practices) are derived from analytical, functional, logical or physical phenomena.
I am looking to obtain some paper relating to the use of architecture or architectural elements that can shape or even influence public behaviour and/or emotions. The topic is immensely brief at this stage and I want to dig deeper into this topic. It is my belief that to some architecture has become irrelevant and that some people have adopted the somewhat stereotypical "four walls and a roof" syndrome. My idea is to lend a different perspective on what architecture really is and how it can provide that "WOW factor" besides just being shelter for the human population.
