Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw-based fasteners are used to fix the ceiling lamp bottom panel, then the fastening connection is reliable, but the mounting and dismounting process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the fastening function from the screw-based system and implements it through a dedicated fastener component with elastic hooks that engage with fixing members. This separate fastener design eliminates the need for screws while maintaining reliable connection, allowing quick snap-in installation without tools.
Solution Approach 2:
The fastener incorporates an elastic member that automatically provides the force needed for engagement and disengagement. The elastic hooks naturally snap into the fixing members during installation and can be easily released by applying force to the position limit column, making the fastening system self-servicing without requiring external tools or complex operations.
2Strength
If conventional screw-based fasteners are used, then the fastening strength is sufficient, but the structure becomes complicated and requires professional tools
Solution Approach 1:
The patent extracts the fastening function from the screw-based system and implements it through a dedicated fastener component with elastic hooks that engage with fixing members. This separate fastener design eliminates the need for screws while maintaining reliable connection, allowing quick snap-in installation without tools.
Solution Approach 2:
The patent changes the fastening mechanism from mechanical screw threads to elastic deformation-based engagement. The elastic member deforms during installation to allow the hooks to engage with the fixing members, then returns to its original shape to provide secure holding force, replacing complex threaded structures with simple elastic geometry.
3Reliability
If multiple screws are used to fix the fastener to the bottom panel, then the connection is secure, but the mounting process requires professional tools and skilled operators
Solution Approach 1:
The fastener incorporates an elastic member that automatically provides the force needed for engagement and disengagement. The elastic hooks naturally snap into the fixing members during installation and can be easily released by applying force to the position limit column, making the fastening system self-servicing without requiring external tools or complex operations.
Solution Approach 2:
The patent extracts the fastening function from the screw-based system and implements it through a dedicated fastener component with elastic hooks that engage with fixing members. This separate fastener design eliminates the need for screws while maintaining reliable connection, allowing quick snap-in installation without tools.

AI summary
The present disclosure provides a fastener and a fastener assembly. The fastener includes a position limit column, an elastic member, and at least one fastening hook. The elastic member is disposed at a bottom portion of the position limit column, the first fixing member includes a fastening hole disposed at a portion corresponding to the fastening hook, and the first fixing member includes a position limit hole disposed at a portion corresponding to the position limit column. When the fastener moves to a predetermined position, the position limit column falls into the position limit hole and the fastening hook engages with the fastening hole, thus, the fastener is fixedly connected with the first fixing member. This kind of fastener has a simple structure and does not need screws for mounting. Mounting and dismounting do not need professional tools, and are convenient and efficient. Thus, this fastener can reduce manpower cost and time cost.
