Adjustable Sensor Band for Universal Rim Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire information acquisition devices face challenges in being cost-effective and easily installable across various rim sizes, as existing band structures are not universally applicable and require dedicated valves for different tire types, leading to increased costs and limited versatility.
Innovation Solution
A tire information acquisition device featuring a sensor unit with an adjustable first band for fixing to the rim and a second band for integral fastening, allowing for adjustable length and breathability, and using non-metal materials to prevent rust, with a base for thermal conductivity control and slippage prevention, enabling wide applicability across various rim sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a band of specific length is used to fix the sensor unit to the rim, then the installation is simplified, but the applicability to various rim sizes is limited
Solution Approach 1:
The band is designed with a dynamic length adjustment mechanism featuring multiple holes at one end and a fastening portion at the other end. The holes allow the band length to be adjusted by selecting different insertion positions, enabling the same band to fit various rim sizes while maintaining simple installation through the reversible fastening mechanism.
2Reliability
If dedicated valves are used for different tire types, then the fixation reliability is improved, but the product management complexity and cost increase
Solution Approach 1:
The band structure is designed as a universal component that can be applied to various tire types including passenger vehicle tires and truck tires. The adjustable length mechanism allows a single band design to serve multiple functions across different rim sizes, eliminating the need for dedicated valves for different tire types while maintaining fixation reliability.
3Reliability
If the first band width is increased to prevent defects during rim mounting, then the mounting reliability is improved, but the material consumption and cost increase
Solution Approach 1:
The band width is optimized to a specific range (5-50mm) that provides sufficient strength and reliability for rim mounting while controlling material consumption. This parameter optimization ensures the band is wide enough to prevent defects during mounting but not excessively wide to waste materials, achieving a balance between reliability and cost-effectiveness.
