Composite Wire Rod Wedge Fixing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing end fixing structures for composite wire rods require costly machinery, skilled labor, and complex procedures, and are not suitable for long-term use due to the need for anti-slipping sheets or resin-based shock-absorbing materials that can deform under continuous stress.
Innovation Solution
A cylindrical wedge body with a conical sleeve that engages with the composite wire rod, providing a high frictional force through microscopic irregularities and a divided structure, eliminating the need for machinery and complex preparations, and allowing for easy attachment without specialized skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-slipping sheets and metallic blades are used with wedge clamping, then the composite wire rod can be fixed under high stress, but the structure becomes complex and requires skilled labor for installation
Solution Approach 1:
The invention extracts and removes the anti-slipping sheet and metallic blade components from the fixing structure, retaining only the essential wedge body that directly contacts and grips the composite wire rod. This simplification maintains the gripping function while eliminating unnecessary complexity.
Solution Approach 2:
Instead of using multiple layers of sheets and blades that间接ly grip the wire rod, the invention inverts the approach by having the wedge body directly contact and grip the wire rod surface, achieving fixation through direct friction and mechanical interlocking.
2Manufacturing precision
If compression processing is performed using a machine apparatus, then the anchor end can be formed, but the cost increases and the process becomes complex
Solution Approach 1:
The wedge body is designed to be self-forming during installation. When the wedge is inserted and driven into position, it automatically deforms and conforms to the composite wire rod shape through its own elastic deformation, eliminating the need for external compression machinery to form the anchor end.
Solution Approach 2:
The wedge body is pre-designed with an elastic structure that allows it to deform during installation. This preliminary design of the elastic structure enables the wedge to automatically adapt to the wire rod shape without requiring post-installation machining or compression processing.
3Object-affected harmful factors
If a halved shock-absorbing sleeve made of zinc is used, then the carbon fiber core is protected from crush damage, but the material cost increases and the structure becomes more complex
Solution Approach 1:
The invention removes the separate shock-absorbing sleeve component entirely. Instead, the wedge body itself is designed with elastic properties that allow it to absorb installation forces and protect the carbon fiber core from crush damage, integrating the protection function into the main fixing component.
Solution Approach 2:
The protective function previously provided by a separate zinc sleeve is merged into the wedge body structure. The elastic material of the wedge body combines both the fixing function and the shock-absorbing protection function in a single integrated component.
4Reliability
If multiple anti-slipping sheets are superposed and precisely positioned, then reliable fixation is achieved, but the installation time increases and skilled labor is required
Solution Approach 1:
The invention segments the fixing function into the wedge body structure itself, which has built-in friction surfaces and gripping features. This eliminates the need for multiple separate anti-slipping sheets, reducing installation steps while maintaining reliable fixation through the integrated design.
Solution Approach 2:
The wedge body is designed to automatically position and grip the composite wire rod through its own geometric features and friction surfaces during insertion. This self-positioning capability eliminates the need for precise manual positioning of multiple sheets and reduces installation time.
