Climbing Rope Induction Fusing for Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing ropes used in net or rope climbing game groups result in braided strings deteriorating and wearing out due to twisting, pulling, and pressing, leading to a reduced product life, as the braid on the steel wire opens and deteriorates over time.
Innovation Solution
A method involving the braiding of conductive wires, preferably steel, with petrol-derivative materials like polyamide or polypropylene, which are then wound around a core rope and processed in an induction machine to fuse with the conductive wire, forming a durable structure resistant to melting, unwinding, and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If polyamide, polypropylene, polyester derivative strings are directly braided over steel wire or chemical adhesive is used, then the ropes can be produced with basic climbing functionality, but the braid opens, deteriorates, and wears out due to twisting, pulling, pressing, reducing product life
Solution Approach 1:
The patent applies induction heating to melt the petrol-derivative material, transforming it from solid to liquid state, allowing it to fuse with the steel wire core. This phase transition creates a strong bond that prevents the braid from opening and deteriorating, directly resolving the contradiction between product life and braid stability
Solution Approach 2:
The patent creates a composite structure by fusing petrol-derivative material (polyamide, polypropylene, or polyester) with steel wire through induction heating. This composite construction combines the strength of steel with the durability of synthetic fibers, preventing wear and deterioration while extending product life
2Reliability
If traditional braiding methods are used without induction processing, then the production process is simpler, but the ropes suffer from opening, deterioration, and wearing out under use conditions
Solution Approach 1:
The patent replaces traditional mechanical braiding and chemical adhesive methods with induction heating technology. The electromagnetic induction process automatically melts and fuses the material to the wire, eliminating the need for complex mechanical braiding systems or chemical adhesives, thus improving reliability while managing production complexity
Solution Approach 2:
The patent changes the physical state of the petrol-derivative material through induction heating, transforming it from solid to molten state temporarily during processing. This parameter change enables the material to flow and fuse with the steel wire, creating a durable bond that resists wear and tear without requiring complex production equipment
