Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the gearbox housing is designed as a single complex piece, then structural strength is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The housing is divided into two identical housing parts that can be manufactured separately using standard molding processes, then joined together. This segmentation allows for simpler, more cost-effective manufacturing of each individual part while maintaining the overall structural integrity of the complete housing assembly.
2Volume of moving object
If the housing is designed to be compact, then space efficiency is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The cooling fins are integrated within the housing structure itself, nested between the two housing parts. This allows the cooling surface area to be maximized within the compact housing volume, enabling effective heat dissipation without increasing the overall size of the gearbox.
3Stability of the object's composition
If the housing is designed for a specific orientation, then structural optimization is improved, but adaptability to different orientations deteriorates
Solution Approach 1:
The housing is designed with symmetric features including identical housing parts, cooling fins arranged on multiple surfaces, and mounting feet positioned to provide stable support in any orientation. This symmetric design allows the gearbox to be installed in any orientation while maintaining structural integrity and proper function.
4Temperature
If cooling fins are added to increase heat dissipation, then thermal performance is improved, but manufacturing complexity increases
Solution Approach 1:
The cooling fins are merged with the housing parts themselves, forming an integrated structure rather than separate components. This allows the cooling function to be achieved while maintaining a simple, cost-effective manufacturing process using standard molding techniques.
