Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the shredding body is made rotatable to switch between working position and storage position, then the compactness and ease of storage are improved, but the device complexity increases due to addition of locking mechanism and rotation joint
Solution Approach 1:
The shredding body is designed to be rotatable about a first axis, allowing it to dynamically switch between a working position (extending outward for operation) and a storage position (retracted for compact storage). This dynamic configuration enables the device to adapt its volume based on operational needs while maintaining structural integrity through the rotation joint and locking mechanism.
2Reliability
If safety interfaces and safety components are added to prevent unauthorized operation, then the safety is improved, but the device complexity increases
Solution Approach 1:
A safety interface is provided that requires a safety component to be properly engaged before the device can operate. This preliminary safety check prevents unauthorized or unsafe operation by blocking the control signal path unless the safety component is in the correct position, thereby ensuring operator protection without requiring complex continuous monitoring systems.
Solution Approach 2:
The safety component acts as an intermediary element between the operator and the shredding body. It mediates the control signal flow, allowing power transmission only when properly engaged, thus providing a simple yet effective safety mechanism that prevents accidental activation while maintaining system simplicity.
3Duration of action of moving object
If the power supply device accommodates large battery packs for extended operation, then the duration of action is improved, but the weight and volume of the device increase
Solution Approach 1:
The power supply device is segmented into a modular battery pack that can be independently accommodated in the power supply chamber. This segmentation allows for flexible configuration where large battery packs can be used for extended operating duration when needed, while the modular design enables easy removal or replacement, effectively managing the weight-tradoff based on specific operational requirements.
