Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for assembling and disassembling interface cards in electronic devices require extra tools and can damage thread structures, leading to inferior assembly strength and inconvenience.
Innovation Solution
A quick releasing mechanism with movable and rotatable constraining components that securely hold the interface card in place without the need for additional tools, allowing for easy assembly and disassembly by manually shifting and rotating components to constrain the card on multiple sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fixing components (screws or bolts) are used to fix the circuit board, then assembly strength is achieved, but assembly/disassembly requires extra tools and thread structures may be damaged after repeated operation
Solution Approach 1:
The patent extracts the threaded connection structure from the fixing mechanism and replaces it with a snap-fit structure consisting of a fixing component with a clamping arm and a corresponding groove on the circuit board. This eliminates the need for threaded holes and screwdrivers, achieving tool-free assembly and disassembly while maintaining assembly strength.
Solution Approach 2:
The fixing component is designed with a resilient clamping arm that can be manually pressed to release the circuit board without external tools. The spring-loaded structure automatically engages with the groove to secure the board, enabling self-servicing assembly and disassembly operations.
2Strength
If conventional fixing components (screws or bolts) are used to fix the circuit board, then assembly strength is achieved, but thread structures may be damaged after repeated operation
Solution Approach 1:
The patent removes the threaded connection structure entirely and replaces it with a snap-fit mechanism where a resilient clamping arm engages with a groove on the circuit board. This eliminates thread damage risks while maintaining secure fixation through elastic deformation and geometric interlocking.
Solution Approach 2:
The fixing mechanism transitions from permanent threaded connections to reversible elastic deformation. The clamping arm's resilient material properties enable repeated engagement and release cycles without structural damage, changing the fixation parameter from plastic deformation (threading) to elastic deformation (spring loading).
3Stability of the object's composition
If a cover is pressed over the circuit board to ensure stable disposal, then stability is achieved, but assembly complexity increases
Solution Approach 1:
The patent merges the fixing function and the cover structure into a single integrated component. The fixing component with its clamping arm is incorporated directly into the cover assembly, eliminating the need for separate fixing hardware and reducing overall assembly complexity while maintaining stability.

AI summary
An electronic device with quick releasing function for an interface card includes a base, a connector and a quick releasing mechanism. The base is adapted to hold the interface card. The connector is disposed on the base to electrically connect with the interface card. The quick releasing mechanism is disposed on the base and includes a first constraining component and a second constraining component. The first constraining component is movably disposed on the base and can be shifted between a releasing position and a constraining position. The first constraining component moves to the constraining position to contact against a side of the interface card opposite to the connector. The second constraining component is disposed on the base and located on another side of the first constraining component to contact against the interface card corresponding to the connector.
