Locking Steel Plate Elastic Hook Anti-Loosening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional locking steel plates used in fracture treatment can become loose due to blood supply and periosteum growth, requiring additional assemblies that complicate operations and potentially harm tissue recovery.
Innovation Solution
A locking steel plate design featuring an elastic block hook and limiting groove within a mounting hole, which secures screws to the plate and prevents loosening without additional assemblies, ensuring stability and minimizing operational inconvenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional assembly is added to prevent the locking steel plate from getting loose, then the reliability of the fixation is improved, but the device complexity and operational convenience deteriorate
Solution Approach 1:
The patent merges the anti-loosening function into the original locking steel plate structure by adding an elastic block hook and limiting groove. These components are integrated with the plate body and mounting hole, eliminating the need for separate additional assemblies while maintaining the reliability of fixation.
Solution Approach 2:
The elastic block hook automatically engages with the screw head and is retained by the limiting groove, creating a self-locking mechanism. This self-service feature prevents loosening through the elastic deformation and geometric constraint of the hook-groove interface without requiring external additional assemblies or complex operational procedures.
2Reliability
If an additional assembly is added to prevent the locking steel plate from getting loose, then the reliability of the fixation is improved, but the ease of operation deteriorates
Solution Approach 1:
The anti-loosening components (elastic block hook and limiting groove) are merged into the original plate structure, maintaining the simplicity of the surgical procedure. The hook engages automatically with the screw head during standard installation, and the limiting groove prevents withdrawal, providing reliability without adding operational steps.
Solution Approach 2:
The elastic block hook performs self-service by automatically deforming to engage the screw head and being retained by the limiting groove. This eliminates the need for additional operational steps or complex manipulation during surgery, preserving ease of operation while ensuring fixation stability.
3Reliability
If an additional assembly is added to prevent the locking steel plate from getting loose, then the reliability of the fixation is improved, but the harm to tissue recovery increases
Solution Approach 1:
The anti-loosening mechanism is merged into the original plate structure, avoiding the introduction of additional foreign bodies that could harm surrounding soft tissue. The elastic block hook and limiting groove are positioned within the mounting hole structure, minimizing interference with adjacent tissue and reducing the risk of infection or irritation.
Solution Approach 2:
The self-locking mechanism through elastic deformation and geometric constraint provides reliability without requiring additional assemblies that could potentially harm tissue. The compact integrated design reduces the number of foreign objects in contact with surrounding soft tissue, thereby reducing harmful effects on tissue recovery.
