Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing mechanisms for electronic device covers require complex operations and are prone to mechanical abrasion, leading to decreased repair efficiency and quality over time due to repeated assembly and disassembly.
Innovation Solution
A quick-releasing fixing mechanism featuring a buckling component with a hooking and pushing portion, actuated by a rotatable shaft body, which alternately engages and disengages the cover from the base using a resilient component to maintain stability without abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw or bolt fixing mechanisms are used to assemble the cover with the frame, then the fixing mechanism provides reliable connection, but the operating process becomes complicated and the fixing component is abraded by repeated operation
Solution Approach 1:
The fixing mechanism is segmented into distinct functional components: a buckling component with hooking portion for engagement, a pushing portion for actuation, and an actuating component with shaft body. This segmentation allows each part to perform its specific function efficiently, enabling simple snap-fit assembly without complex screw operations while maintaining reliable connection through the hooking portion's engagement with the cover's constraining portion.
Solution Approach 2:
The invention inverts the traditional fixing approach by using a snap-fit mechanism where the buckling component's hooking portion engages with the cover's constraining portion, rather than using screws that require threading and tightening. The pushing portion acts to disengage the hooking portion from the constraining portion, creating a simple push-to-release mechanism that eliminates complicated assembly operations while maintaining secure connection during normal use.
2Reliability
If conventional screw or bolt fixing mechanisms are used to assemble the cover with the frame, then the fixing mechanism provides secure connection, but the fixing component is abraded by repeated operation decreasing operational period
Solution Approach 1:
The invention extracts the problematic threaded connection element (screw/bolt) from the fixing mechanism and replaces it with a snap-fit system. The buckling component's hooking portion engages with the cover's constraining portion through a simple insertion motion, eliminating the threaded structure that is prone to abrasion. This extraction of the threading mechanism removes the source of mechanical wear while maintaining secure connection through the geometric interlocking of the hooking and constraining portions.
Solution Approach 2:
The buckling component and cover are designed as disposable or replaceable units with simple geometric features rather than durable threaded components. The snap-fit mechanism uses basic plastic deformation and geometric interlocking that can be manufactured economically and replaced easily if worn, rather than attempting to create indefinitely reusable threaded connections that are susceptible to abrasion and thread stripping over repeated operations.
3Reliability
If conventional screw or bolt fixing mechanisms are used to assemble the cover with the frame, then the connection is tightly secured, but the operating process is complicated reducing repair efficiency
Solution Approach 1:
The buckling component is pre-formed with the hooking portion and pushing portion integrated into its structure. The hooking portion is pre-configured to engage with the cover's constraining portion during a single insertion motion, eliminating the need for separate threading and tightening operations. This preliminary configuration of the fixing geometry enables rapid assembly and disassembly, significantly improving repair efficiency while maintaining secure connection through the pre-designed engagement features.
Solution Approach 2:
The fixing mechanism incorporates dynamic characteristics through the pushing portion that can actively disengage the hooking portion from the constraining portion. This dynamic actuation allows the cover to be quickly released by simply pushing the buckling component, rather than requiring time-consuming unscrewing operations. The dynamic push-to-release mechanism maintains tight connection during normal use while enabling rapid disassembly for repairs, thereby improving productivity without sacrificing connection reliability.

Function Achieved in This Case
The mechanism simplifies assembly and disassembly processes, maintaining engagement stability and increasing operational efficiency by allowing easy and repeated use without mechanical deterioration.
Implementation Method 1
The first wedging portion is formed on an inner wall of the hole. The second wedging portion is formed on the shaft body and wedged with the first wedging portion. The shaft body is adapted to revolve on a structural axial direction of the shaft body to switch the buckling component between a first position and a second position.

AI summary
A fixing mechanism with quick-releasing function for assembling a cover with a base includes a buckling component and an actuating component. The buckling component includes a main body, a first wedging portion, a hooking portion and a pushing portion. The first wedging portion is disposed on a hole on the main body. The hooking portion and the pushing portion are disposed on the main body and respectively protrude from the main body at different directions. The actuating component includes a shaft body and a second wedging portion. The hooking portion is engaged with a constraining portion of the base to constrain a movement between the base and the cover while the buckling component is in the first position. The pushing portion pushes the constraining portion to separate the base and the cover while the buckling component is in the second position.
