Board Card Fixing Device with Automatic Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for board cards are cumbersome, as they require manual removal and reinsertion of fixing components, which can lead to the card falling out due to shaking or user forgetfulness, and the fixing process is complicated and inconvenient.
Innovation Solution
A fixing device with a base, fastening assembly, and recovery members that automatically secure and release the board card during insertion and ejection, using a sliding and rotation mechanism with abutting and latch ends, and elastic recovery members to maintain the card's position and facilitate easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed component is used to secure the board card, then the card stability is improved, but the operation complexity increases and the card ejection becomes inconvenient
Solution Approach 1:
The fixing component is designed to be movable rather than fixed, allowing it to automatically adjust between locked and unlocked states. The component can swing between positions to clamp or release the board card, eliminating the need for manual removal and reinsertion while maintaining stable fixation during operation.
Solution Approach 2:
The fixing component is equipped with automatic locking and unlocking mechanisms that activate based on card insertion or ejection actions. The system self-regulates the fixing state without requiring user intervention, thereby maintaining card stability while simplifying operations.
2Ease of operation
If the fixing device is shaken, then the card can be accessed, but the fixing component may fall off causing the card to fall out
Solution Approach 1:
The fixing component is designed with a constrained movement path guided by rails or slots in the base, preventing it from falling off during shaking or vibration. The component can still perform its clamping function while its movement is limited to a controlled trajectory, ensuring reliability during dynamic conditions.
3Stability of the object's composition
If the fixed component blocks the insertion path, then the card can be secured, but the insertion process becomes complicated
Solution Approach 1:
The fixing component automatically moves out of the insertion path during card insertion and then swings into position to clamp the card after insertion. This dynamic movement eliminates the need for manual component removal, simplifying the insertion process while ensuring proper card fixation.
Solution Approach 2:
The fixing component is pre-positioned to automatically retract or swing away from the insertion path before the card arrives, and then automatically engages to secure the card. This preliminary positioning action eliminates the need for manual intervention and reduces insertion complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device automatically secures and releases the board card, preventing it from falling out and simplifying the insertion and ejection process, ensuring stability and convenience for users.
Implementation Method 1
a first recovery member configured to move the fastening assembly from the fixed position toward an entrance of the rail when the locked status is released
Implementation Method 2
a second recovery member connected to the base and configured to apply a force to the rotation member to move the abutting end toward the rail and move the latch end away from the rail

AI summary
A fixing device includes a base, a fastening assembly, a fixing assembly and a first recovery member. The base has a rail be inserted by a board card. The fastening assembly is movably coupled to the base and detachably secures the board card. The fastening assembly includes a sliding member and a rotation member. The sliding member is slidably connected to the base. The rotation member is pivotally connected to the sliding member and includes an abutting end and a latch end. The rotation member selectively causes the abutting end and the latch end to be inserted into the rail. The fixing assembly is connected to the base and the fastening assembly, and secures the fastening assembly in a locked status. The first recovery member moves the fastening assembly from the fixed position toward an entrance of the rail when the locked status is released.
