Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strain relief devices for cables are either complex to manufacture or limited in their ability to withstand high tensile forces, making them unsuitable for a wide range of applications.
Innovation Solution
A strain relief device comprising two identically configured halves with clamping portions and an attachment portion, allowing for easy assembly and secure clamping of cables, using identical parts to simplify manufacturing and accommodate high tensile forces through latching connections and flexible connecting portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an elastic ring pressed by a threaded union is used for strain relief, then the device is simple to manufacture, but it cannot withstand high tensile forces
Solution Approach 1:
The strain relief device is divided into two separate halves that can be assembled around the cable, allowing each half to be简单地 manufactured while together providing high tensile strength through the clamping mechanism
Solution Approach 2:
The device transitions from a single continuous ring to two separable halves with clamping portions, changing the structural parameter to enable both ease of manufacture and high strength performance
2Strength
If two pieces pivotally connected by hinges with internal threading are used, then high tensile forces can be resisted, but the device becomes complex to manufacture
Solution Approach 1:
The complex hinge connection and internal threading are extracted and replaced with a simpler clamping mechanism using clamping portions and retaining members that can be easily assembled without complex fastening systems
Solution Approach 2:
Instead of using hinges to connect pieces that then clamp the cable, the invention inverts the approach by having two halves with clamping portions that directly clamp the cable, eliminating the need for complex hinge mechanisms
3Strength
If cable binders are tightly mounted to withstand high tensile forces, then the device can resist higher forces, but it becomes prone to failure in use
Solution Approach 1:
The clamping portions are pre-configured with retaining members and attachment portions that are spaced apart, allowing the cable to be securely clamped before tensile forces are applied, preventing premature failure
Solution Approach 2:
The attachment portion is specifically positioned spaced apart from the clamping portions, creating a local structural feature that distributes forces and prevents concentration of stress that would lead to failure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the device to securely retain cables under high tensile forces, with the ability to withstand forces over 667 N for 1 minute with minimal displacement, while being simple to manufacture and versatile in application.
Implementation Method 1
