Flat Panel Placement Mechanism with Rotating Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat panel placement mechanisms for digital X-ray imaging are unreliable and unsatisfactory in terms of ergonomics, as they fail to prevent the flat panel from jumping out in seismic environments and are difficult to operate safely, often resulting in damage to the panel during placement or removal.
Innovation Solution
A placement mechanism with a limiting assembly comprising first and second limiting blocks and a locking portion, which includes a locking member that can be adjusted for friction force, allowing for secure locking and unlocking of the flat panel along the height direction without requiring both hands, and a drag reducing portion to minimize wear and enhance ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed plate and card holders are used to limit three corners of the flat panel, then the flat panel is fixed in position, but the mechanism cannot effectively prevent the flat panel from jumping out in a seismic environment
Solution Approach 1:
The limiting assembly is divided into multiple independent limiting blocks (first limiting block and second limiting block) that separately constrain different sides of the flat panel. Each limiting block can independently provide limiting force, ensuring reliable fixation while maintaining modular structure that avoids excessive complexity.
Solution Approach 2:
The locking member acts as a counterbalancing element that applies opposing force to prevent the flat panel from jumping out during seismic conditions. The locking member can be rotated to engage with the limiting blocks, creating a counteracting mechanical constraint that balances the disruptive seismic forces.
2Reliability
If the flat panel is fixed by a locking structure requiring manual operation, then the flat panel can be securely locked, but the appearance of the flat panel is easily scratched and both hands are required to unlock
Solution Approach 1:
The locking member is designed to be rotatable and can be operated with a single hand. The rotation mechanism allows the locking member to engage or disengage from the limiting blocks automatically through rotational motion, eliminating the need for two-handed operation and reducing the risk of scratching the flat panel surface during manipulation.
Solution Approach 2:
The locking member transitions from a static fixed position to a dynamic rotatable state, allowing it to switch between locked and unlocked positions through rotation. This dynamic capability enables single-handed operation while maintaining secure locking when engaged, resolving the contradiction between reliability and ease of operation.
3Reliability
If the flat panel must be parallel to the fixed plate for placement, then the limiting structure works effectively, but the operation is not easy to perform
Solution Approach 1:
The limiting blocks are positioned at different spatial locations (first limiting block at first end, second limiting block at second end) to create a three-dimensional limiting structure. This spatial distribution allows the flat panel to be constrained effectively while accommodating easier placement operations, as the limiting forces are distributed across multiple dimensions rather than requiring precise parallel alignment.
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 mechanism effectively secures the flat panel against displacement in seismic environments, improves operational convenience by allowing single-handed operation, and reduces the risk of damage during placement and removal, while maintaining stability and reliability.
