Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable battery is used in the vehicle-mounted refrigerator, then the convenience of battery installation and removal is improved, but the structure becomes more complex and costly due to the need for springs and locking mechanisms
Solution Approach 1:
The battery system is divided into separate components: a removable battery pack and a refrigerator body with a dedicated battery chamber. This segmentation allows the battery to be easily installed and removed without affecting the overall refrigerator structure, solving the contradiction between ease of operation and structural complexity.
Solution Approach 2:
The battery is extracted as a completely separate, removable component from the refrigerator system. The battery pack can be taken out and replaced independently, eliminating the need for complex internal mounting mechanisms while maintaining ease of installation and removal.
2Ease of operation
If springs are used in the battery structure to enable removal, then the ease of battery installation is improved, but the reliability decreases due to jamming and wear
Solution Approach 1:
The traditional spring-based mechanical retention system is replaced with a simpler friction-fit or snap-fit mechanism. This substitution eliminates the moving parts and elastic elements that cause jamming and wear, thereby improving reliability while maintaining ease of installation.
3Ease of operation
If a telescopic pull rod is provided without a locking mechanism, then the ease of movement is improved, but the reliability decreases due to accidental extension and damage
Solution Approach 1:
The pull rod incorporates an automatic locking mechanism that engages when the rod reaches its extended position. This self-service feature ensures the rod remains locked without requiring user intervention, preventing accidental extension and damage while maintaining ease of movement when needed.
Solution Approach 2:
The locking mechanism is designed to automatically engage and prevent further extension of the pull rod before damage can occur. This preliminary anti-action counteracts the potential harmful effect of over-extension, ensuring reliability while preserving mobility.
4Device complexity
If a single-function refrigerator design is used, then the device complexity is reduced, but the adaptability decreases to meet diverse customer needs
Solution Approach 1:
The refrigerator is designed with multiple functions integrated into a single device: refrigeration, freezing, and a detachable fruit cutting board. This multi-functionality increases adaptability to meet diverse customer needs while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The fruit cutting board is merged with the refrigerator body as a detachable component. This combination allows the refrigerator to serve dual purposes (cooling and food preparation) without significantly increasing structural complexity, as the cutting board can be removed when not needed.

Function Achieved in This Case
The solution provides a convenient, reliable, and versatile refrigeration system with diverse functions, preventing pull rod damage and eliminating the need for additional cutting boards, enhancing user experience and reducing operational complexity.
Implementation Method 1
The buckle plates at both ends are connected together by an elastic piece. The elastic piece is disposed in a limit groove defined in an inner side of the battery cover.
Implementation Method 2
One end of the lock tongue is equipped with a spring, and the other end is inserted into a lock hole defined in the side wall of the pull rod fixing tube.
