Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple conductive plate structure is used, then the device complexity is reduced, but the connection stability under external vibrations deteriorates
Solution Approach 1:
The conductive plate is segmented into functionally distinct regions: a connection unit for electrical connection and an extension unit with damping portions for vibration absorption. This segmentation allows each part to perform its specific function optimally while maintaining overall structural integrity and connection stability under vibration.
Solution Approach 2:
The damping portions extend in multiple directions (first direction from one side, second direction from the other side) perpendicular to the main plate plane, adding dimensional complexity to absorb vibrations from different directions. This multi-directional extension provides comprehensive vibration damping while maintaining a relatively simple overall structure.
2Reliability
If damping portions are added to absorb vibrations, then the connection stability is improved, but the device complexity increases
Solution Approach 1:
The damping portions are merged with the conductive plate as an integrated structure rather than separate components. The extension unit with damping portions is formed as a continuous piece with the connection unit, eliminating the need for additional fasteners or mounting hardware while providing vibration damping functionality.
Solution Approach 2:
The conductive plate serves multiple functions: it provides electrical connection through the connection unit and simultaneously absorbs vibrations through the damping portions. This multi-functionality reduces the need for separate vibration damping components, maintaining structural simplicity while improving connection stability.
3Ease of manufacture
If the conductive plate structure is simplified, then the ease of manufacture is improved, but the ability to resist external vibrations deteriorates
Solution Approach 1:
The damping portions are designed with bent configurations that allow dynamic deformation under vibration loads. The bent shapes can flex and absorb vibrational energy through elastic deformation, providing vibration resistance while maintaining a relatively simple manufactured structure that can be formed through standard bending processes.
