Flexible Band Module Fixing for Tire Inner Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for fixing electronic modules to the internal wall of tires, particularly those with large dimensions, fail to ensure durability under high stress conditions such as significant deflections and load increases, which can lead to detachment and damage.
Innovation Solution
A device comprising a base fixed to the tire with a flexible band that has independent attachment means at its ends, allowing for stress absorption and distribution, ensuring the module remains securely attached during tire deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid fixing system is used to secure the module firmly, then the attachment strength is improved, but the system becomes unable to withstand tire deflections and deformations
Solution Approach 1:
The patent employs a flexible band made of elastic material that wraps around the module and attaches to the tire wall. This flexible band can deform with the tire during deflection and deformation cycles while maintaining attachment strength, resolving the contradiction between rigid fixation and flexibility requirements.
Solution Approach 2:
The fixing system utilizes materials with specific elastic properties that allow the band to stretch and deform elastically under tire stress. The elastic modulus and tensile strength parameters of the band material are selected to accommodate tire deflections of 30% while maintaining sufficient attachment force.
2Reliability
If the module is firmly attached to withstand high stresses, then the reliability is improved, but the complexity of the fixing device increases
Solution Approach 1:
The fixing device is segmented into three main components: a base attached to the tire wall, a flexible band that wraps around the module, and independent attachment means at the ends of the band. This segmentation allows each component to perform its specific function simply, achieving high reliability without excessive overall complexity.
Solution Approach 2:
The flexible band's elastic properties provide self-adjusting tension that automatically adapts to tire deflections and module positioning variations. The elastic deformation of the band itself provides the necessary attachment force, eliminating the need for additional active components or complex control mechanisms.
3Ease of manufacture
If a simple attachment system is used, then the ease of manufacture is improved, but the attachment cannot withstand significant deflections and load increases
Solution Approach 1:
The flexible band serves as both the structural element and the attachment mechanism, combining simplicity of form with effectiveness in stress resistance. The elastic material properties provide the necessary strength to withstand deflections and load increases without requiring complex reinforcement or additional components.
Solution Approach 2:
The fixing device combines different materials with complementary properties: the base material for attachment to the tire wall, and the elastic flexible band material for wrapping and securing the module. This composite approach achieves high stress resistance through material selection rather than structural complexity.
