Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated mounting mechanisms are used to secure the battery unit reliably and provide anti-theft protection, then the reliability and security are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The mounting mechanism is divided into separate functional modules: guiding means for positional control and locking means for security. This segmentation allows each module to perform its specific function efficiently without requiring a complex integrated system, thereby reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The patent replaces complex mechanical locking mechanisms with an electrically driven locking element that can be controlled electronically. This substitution reduces mechanical complexity and enables remote monitoring and control of the battery mounting status, improving reliability without increasing device complexity.
2Reliability
If sophisticated mounting mechanisms are used to ensure secure electrical connection and anti-theft protection, then the security and connection reliability are improved, but the manufacturing cost increases
Solution Approach 1:
The guiding means serves multiple functions: it guides the battery unit during installation, provides positional control, and works in conjunction with the locking means to ensure secure mounting. This multi-functionality reduces the need for separate components, thereby lowering manufacturing costs while maintaining connection security and reliability.
Solution Approach 2:
The electrically driven locking element replaces complex mechanical locking and electrical connection mechanisms with a single integrated electrical actuation system. This reduces the number of parts that need to be manufactured and assembled, lowering manufacturing costs while ensuring secure electrical connection and anti-theft protection.
3Device complexity
If manual locking mechanisms are used, then the device complexity is reduced, but the ease of operation and theft protection capability deteriorate
Solution Approach 1:
The patent replaces manual mechanical locking operations with an electrically driven locking element that can be actuated through electrical signals. This improves ease of operation by eliminating manual manipulation of locking components while maintaining simplicity in the overall device architecture. The electrical actuation enables remote or automated locking, enhancing theft protection without significantly increasing device complexity.
4Ease of operation
If the battery unit is movable between positions for easy installation, then the ease of operation is improved, but the security and anti-theft protection deteriorate
Solution Approach 1:
The patent implements a dynamic mounting system where the battery unit can be freely moved along the guiding means during installation, but the electrically driven locking element can be activated to securely fix the battery in its final position. This dynamic behavior allows the system to adapt to different operational requirements: movable during installation for ease of operation, and fixed during use for security and anti-theft protection.
