Contact-Free Cable Tie Retainer for Heat-Safe Material Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for cable ties are inadequate for securely binding materials with varying diameters and temperatures exceeding 100°C, often requiring multiple components and risking damage or heat transfer to the material.
Innovation Solution
A fastening system comprising a holding device with guide grooves and a cable tie that accommodates different diameters, allowing the cable tie to be inserted and secured without direct contact, maintaining a distance from the material, and using a combination of hard and soft components for enhanced stability and thermal protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid clamp is used to secure binding material, then the binding material is securely held, but the clamp can only accommodate a narrow range of diameters requiring multiple different embodiments
Solution Approach 1:
The holding device incorporates a flexible membrane element that can dynamically adapt its shape and size to accommodate binding materials of different diameters. The membrane can be deformed elastically to match various circumferences, transforming a static rigid structure into a dynamic adaptive one, thereby eliminating the need for multiple fixed-diameter clamps.
Solution Approach 2:
The holding device allows change in the geometric parameters of the binding material accommodation space through elastic deformation of the membrane. By adjusting the membrane's degree of expansion or contraction, the same device can securely hold binding materials ranging from small to large diameters, effectively changing the device's functional parameters without requiring physical replacement.
2Reliability
If the holding device directly contacts the binding material, then secure binding is achieved, but mechanical and thermal stress is applied to the material
Solution Approach 1:
A cable tie serves as an intermediary element between the holding device and the binding material. The cable tie is tightened around the binding material to provide secure mechanical binding, while the holding device secures the cable tie rather than directly gripping the binding material. This intermediary arrangement reduces direct mechanical stress and thermal contact on the binding material.
Solution Approach 2:
The holding device uses a flexible membrane that can conform to the shape of the cable tie and binding material without applying excessive localized stress. The flexible nature of the membrane allows it to distribute forces more evenly, reducing mechanical stress concentrations and minimizing thermal contact area with the binding material.
3Adaptability or versatility
If multiple components are used to secure binding material with varying diameters and temperatures, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The holding device is designed as a universal multi-functional component that can accommodate binding materials of various diameters and temperatures through its flexible membrane and cable tie mechanism. Rather than requiring separate specialized clamps for different diameter ranges or temperature conditions, this single device performs multiple functions by adjusting the membrane deformation and cable tie tension, thereby reducing overall system complexity and component count.
