Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing devices with separate fixed and retractable coupling portions are used, then the case can be securely attached to the DIN rail, but the coupling and uncoupling operations become cumbersome requiring rotation and ample maneuvering space
Solution Approach 1:
The patent combines the fixed coupling portion and the retractable coupling portion into a single integrated body. The body includes a first coupling portion that remains stationary and a second coupling portion that can retract, both working together to secure the case to the DIN rail. This merging eliminates the need for separate coupling mechanisms and simplifies the overall operation while maintaining secure attachment.
Solution Approach 2:
The patent introduces a retractable second coupling portion that can dynamically change its position between extended and retracted states. This dynamic element allows the device to adapt during coupling and uncoupling operations, enabling simple perpendicular movement without rotation while maintaining secure attachment when engaged.
2Reliability
If conventional fixing devices requiring rotation are used, then secure attachment is achieved, but the maneuvering space required increases and operation time increases
Solution Approach 1:
The retractable second coupling portion enables the device to transition between coupled and uncoupled states through simple perpendicular movement along the DIN rail, eliminating the need for rotational maneuvering and reducing the space required for operation.
3Reliability
If conventional fixing devices with separate coupling portions are used, then the case can be attached to the DIN rail, but the time required for coupling and uncoupling operations increases
Solution Approach 1:
By integrating both coupling portions into a single body with coordinated movement, the patent enables simultaneous engagement and disengagement of both coupling points, significantly reducing the time required for coupling and uncoupling operations while maintaining secure attachment.
Solution Approach 2:
The retractable second coupling portion works in coordination with the first coupling portion to enable rapid simultaneous engagement and disengagement, improving coupling speed and productivity.
4Reliability
If conventional fixing devices are used, then the case can be attached to the DIN rail, but simultaneous coupling of both coupling portions is not possible
Solution Approach 1:
The patent merges the two coupling portions into a single integrated body where their movements are coordinated through the body's structure. This allows both coupling portions to be engaged and disengaged simultaneously in a single perpendicular motion, simplifying the coupling mechanism while maintaining reliable attachment.
