Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple components are contained compactly within a limited space, then space utilization is improved, but component accessibility for repair and replacement deteriorates
Solution Approach 1:
The support bracket is segmented into multiple functional zones: a first region for supporting the electrical component, a second region with apertures for terminal connections, and a third region for coolant connections. This segmentation allows each zone to be optimized independently, enabling compact overall design while maintaining accessibility to specific components through dedicated access paths.
Solution Approach 2:
The support bracket utilizes three-dimensional spatial arrangement by extending in multiple directions from a central structure. Electrical components are positioned in one region while connection apertures are distributed across different spatial zones, allowing compact packaging in one dimension while maintaining accessibility in other dimensions through strategically placed openings and access points.
2Stability of the object's composition
If components are supported securely within the assembly, then structural stability is improved, but device complexity deteriorates
Solution Approach 1:
The support bracket is designed as a multi-functional universal structure that simultaneously performs multiple functions: supporting electrical components, providing terminal connections through apertures, enabling coolant fluid passages, and offering structural mounting points. This consolidation of multiple functions into a single bracket reduces the number of separate support structures needed, thereby reducing overall device complexity while maintaining structural stability.
Solution Approach 2:
Multiple support functions are merged into a single integrated bracket structure. The bracket combines mechanical support, electrical connection pathways, and fluid connection features into one unified component, eliminating the need for separate support structures for each function and simplifying the overall assembly.
3Adaptability or versatility
If terminal connections are provided for electrical and coolant connections, then connection functionality is improved, but manufacturing complexity deteriorates
Solution Approach 1:
The support bracket is designed with pre-formed apertures and integrated connection features that are incorporated during the bracket manufacturing process itself. Terminal connections and coolant passage openings are built into the bracket structure before final assembly, eliminating the need for post-assembly modification or complex field installation procedures.
Solution Approach 2:
The bracket incorporates multiple types of connections (electrical terminals and coolant passages) within a single universal structure. This multi-functional design allows the same bracket to handle both electrical and fluid connections, reducing the number of separate components needed and simplifying the manufacturing process compared to producing separate specialized brackets for each connection type.
