Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blocking element forms part of the overall locking configuration with simultaneous displacement and locking, then the system ensures safety, but the freedom of positioning is limited and ease of use deteriorates
Solution Approach 1:
The locking function and positioning function are segmented into separate mechanisms: the gear rack system provides independent positioning freedom, while the blocking element provides separate locking action. This allows the displaceable body to be positioned anywhere along the guiding rail before locking, rather than requiring simultaneous alignment during a single displacement action.
Solution Approach 2:
The system transitions from a static simultaneous locking-positioning mechanism to a dynamic two-stage process where positioning and locking can occur at different times and positions, providing flexibility in operation while maintaining safety.
2Reliability
If the blocking element forms part of the overall locking configuration, then the system ensures safety, but the degree of freedom is limited due to alignment requirements
Solution Approach 1:
The system separates the locking function (blocking element) from the positioning function (gear rack mechanism), allowing independent operation. The displaceable body can be positioned at any location along the guiding rail using the gear racks, then locked separately using the blocking element, providing full adaptability in positioning while maintaining safety through locking.
Solution Approach 2:
The system performs preliminary positioning of the displaceable body to the desired location using the gear rack mechanism before engaging the blocking element for locking. This preliminary positioning action enables freedom of placement while ensuring subsequent safety through separate locking.
3Device complexity
If a single action is used to align the guiding rail, displaceable body and blocking element, then the system is simple, but the ease of use deteriorates and positioning freedom is limited
Solution Approach 1:
The system segments the alignment process into two independent stages: first, positioning the displaceable body along the guiding rail using gear racks; second, locking the position using the blocking element. This segmentation increases operational ease and positioning freedom while maintaining acceptable system complexity through modular design.
Solution Approach 2:
The system employs dynamic, multi-step operation rather than static single-action alignment. The operator can displace the body to any position using the gear rack mechanism, then engage locking separately, providing flexibility and ease of use while keeping the overall system structure relatively simple.
