Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking system with multiple protrusions is used to secure the drive battery, then the reliability of battery attachment is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The locking system is segmented into two functional parts: a mounting projection with head and shaft sections that provides positioning, and a separate locking lever with locking element that provides securation. This segmentation allows each component to perform its specific function efficiently without the complexity of an integrated multi-protrusion system.
Solution Approach 2:
The mounting projection with its head section performs preliminary positioning and alignment of the drive battery before the locking lever engages. This preliminary action guides the battery into the correct position, making the subsequent locking action simpler and more reliable.
2Reliability
If a complex locking system with multiple protrusions is used, then the reliability of battery attachment is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The locking lever is designed as a dynamic element that can be easily actuated to engage and disengage the locking element with the locking recess. This dynamic design allows quick one-handed operation for assembly and disassembly, contrasting with static multi-protrusion systems that require manual manipulation of multiple components.
Solution Approach 2:
The locking function is extracted as a separate operable lever rather than being integrated into the mounting structure itself. This extraction allows the user to operate the locking mechanism independently and easily, improving assembly and disassembly ease while maintaining secure attachment.
3Reliability
If multiple protrusions are used for mounting, then the reliability of drive battery positioning is improved, but the device complexity increases
Solution Approach 1:
Different sections of the mounting projection have different local qualities: the head section provides lateral positioning with its larger dimensions, while the shaft section provides vertical positioning and engagement. This localized functional differentiation achieves reliable positioning without requiring multiple separate protrusions.
Solution Approach 2:
The mounting projection serves multiple functions: positioning the drive battery laterally, positioning it vertically, and providing a pivot point for the locking lever. This multi-functionality reduces the need for multiple separate mounting features, simplifying the overall structure while maintaining positioning reliability.
