Flexible Cord Protector for Power Winch Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent collisions between the hook head and the discharging seat or four-way roller set in power winches lead to damage, noise, and safety issues, affecting the operational reliability and user safety.
Innovation Solution
A cord protector composed of two protection seats made of flexible material, designed to absorb impact and prevent direct contact between the hook head and the discharging seat or four-way roller set, using an arc cone shape with recessed openings and grooves to securely clamp the cord and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hook head is made of rigid metal material to ensure strength for hoisting heavyweights, then the strength is improved, but collision damage and noise occur during cord retraction
Solution Approach 1:
A cord protector made of flexible material is introduced as an intermediary component between the hook head and the discharging seat/roller set. This protector absorbs impact forces during cord retraction, preventing direct collision between rigid metal parts while maintaining the hook head's structural integrity and strength for heavyweight hoisting.
Solution Approach 2:
The cord protector is constructed from flexible material that can deform to absorb impact energy. This flexible component wraps around or positions between rigid parts, providing cushioning during cord retraction without compromising the structural strength of the metal hook head when under load.
2Stability of the object's composition
If the discharging seat or four-way roller set is made of rigid metal material to provide structural support, then the structural stability is improved, but collision damage and noise occur during cord retraction
Solution Approach 1:
The flexible cord protector serves as a mediator between the rigid discharging seat/roller set and the moving cord assembly. It absorbs impact forces during retraction, protecting the rigid structural components from damage and reducing noise while the discharging seat maintains its structural stability for supporting the mechanism.
3Object-affected harmful factors
If the cord protector is made of flexible material to absorb impact, then collision damage is prevented, but the material must resist pull forces during cord operation
Solution Approach 1:
The cord protector is made from composite or specially formulated flexible material that combines high tensile strength with impact absorption capabilities. This allows the protector to withstand pull forces during cord operation while simultaneously absorbing impact energy during retraction to prevent collision damage.
Solution Approach 2:
The flexible material's mechanical properties are optimized to exhibit different characteristics under different loading conditions: high elasticity and energy absorption during impact, and high tensile strength during pull operations. This parameter optimization allows the single material to satisfy both contradictory requirements.

AI summary
A cord protector is combined with a cord to protect the cord. An outermost end head of the cord would revolve and is fixedly connected to the cord through a collar. The cord protector is assembled by a first protection seat and a second protection seat. The first protection seat and the second protection seat are made of flexible material resisting impact. Openings at the bottom of the first protection seat and the second protection seat co-clamp the cord. A top portion of the first protection seat is divided into two through grooves by a cross bar. Two side cord bodies of a revolving combination place of the cord respectively enter the two through grooves of the first protection seat and are joined by joining members. With the composition, it prevents collision between combined rigid components to protect the combined rigid components and operating users, thereby increasing use safety.
