Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting methods are used, then the storage device can be securely fixed, but the mounting and dismounting process becomes cumbersome and requires separate tools
Solution Approach 1:
The patent combines the mounting and dismounting functions into a single integrated latch assembly. The latch assembly includes a latch body with a latch arm that can engage with the storage device, and a actuator that controls the latch arm movement. This integration eliminates the need for separate mounting tools and simplifies the overall mounting process while maintaining secure fixation.
Solution Approach 2:
The latch assembly is designed to be self-operating through the elastic member (spring) that automatically returns the latch arm to the engaged position after actuation. The elastic member stores mechanical energy during the disengagement process and releases it to automatically reset the latch, eliminating the need for additional tools or complex resetting mechanisms.
2Ease of operation
If a simple attachment mechanism is used, then mounting and dismounting becomes easy, but the coupling force and reliability decrease
Solution Approach 1:
The latch arm features a curved engagement surface that mates with a corresponding curved surface on the storage device. This curved geometry provides progressive engagement and disengagement, allowing the latch to smoothly transition between states while maintaining consistent contact pressure. The curved surfaces distribute mechanical stresses more evenly, enhancing both the ease of operation and the reliability of the coupling.
Solution Approach 2:
The latch assembly incorporates an elastic member (spring) that provides dynamic response to mounting and dismounting forces. The spring allows the latch arm to flex during engagement, absorbing shock and maintaining optimal contact pressure. This dynamic element ensures reliable coupling while requiring minimal force for operation, resolving the contradiction between ease of use and coupling strength.

AI summary
An extension kit includes a case, a locking lever, and a first elastic member. The case has an interior space which extends in a first direction. The locking lever includes a lever portion which is rotatable about a first rotation axis extending in a second direction intersecting the first direction, a plate portion which extends from the lever portion and which is exposed at the case, an arm portion which extends in the second direction from the plate portion, and a first locking portion which protrudes from the arm portion. The first elastic member is provided in the interior space of the case and elastically connects the case and the locking lever in the interior space of the case.
