Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screws and screwdrivers are used to mount card modules, then the connection is stable, but the mounting and dismounting process becomes inconvenient and requires tools
Solution Approach 1:
The fixing module is divided into distinct functional components: a base fixed to the case, a sliding element that moves along the base, a resilient portion providing elastic force, and a locking bracket on the card module. This segmentation allows each component to perform its specific function independently, enabling tool-free operation while maintaining connection stability.
Solution Approach 2:
The resilient portion automatically exerts elastic restoring force to push the sliding element against the locking bracket, creating a self-locking mechanism. When the card module is inserted, the sliding element is pushed against the resilient portion, which automatically engages the locking structure without requiring user intervention or tools. The system serves itself by using the insertion force to trigger the locking action.
2Ease of operation
If a simple locking mechanism is used, then the ease of operation improves, but the reliability of the connection may deteriorate
Solution Approach 1:
The resilient portion is designed with an S-shaped curved structure that provides progressive elastic restoring force. This curved geometry allows the resilient portion to exert increasing force as the sliding element moves into the locked position, ensuring reliable engagement while maintaining ease of operation. The curved shape also allows for smooth locking and unlocking actions.
Solution Approach 2:
The resilient portion changes its elastic deformation parameters during the locking process. When the card module is inserted, the resilient portion deforms elastically and stores energy, then releases this energy to push the sliding element into the locked position against the locking bracket. This dynamic parameter change ensures both easy operation and reliable connection.

AI summary
A fixing module for fixing a card module and a case having the fixing module are provided. The fixing module includes a base and a sliding element. The base is disposed on a bracket and includes a carrying portion, a cantilever hook, and a constraining structure. The sliding element includes a resilient portion and a body. The body is movably disposed on the carrying portion of the base. The constraining structure is adapted to contact the body and constrain a movement of the body when the sliding element is in a locked position, and the resilient portion constrains the locking bracket of the card module on the bracket. When a force is exerted on the cantilever hook to disengage the constraining structure from the body, the sliding element is moved to an unlocked position under the influence of an elastic restoring force of the resilient portion.
