Vehicle Wheel Sensor Housing Segmented Breaking Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire-mounted sensor systems face challenges in easy and reproducible dismounting without tool usage and risk improper reuse due to lack of standardization and damage during removal with undefined tools.
Innovation Solution
A sensor housing with a recess featuring a predetermined breaking point allows tool-less release and secure destruction, ensuring the sensor can be easily removed and reused or securely destroyed, using a material narrowing or a strap at the breaking point for easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensors are removed with knives or unsuitable tools, then the sensor can be separated from the tire, but the sensor housing may be damaged and improper reuse may occur
Solution Approach 1:
The receiving area is segmented into two parts: a first part that holds the sensor and a second part that can be separated. The predetermined breaking point is located at the interface between these parts, allowing controlled separation that releases the sensor while preserving the housing structure for potential reuse.
Solution Approach 2:
The predetermined breaking point is pre-formed in the receiving area during manufacturing, preparing the structure for future controlled separation. This preliminary action ensures that when separation is needed, it occurs at the intended location without damaging the sensor housing or enabling improper reuse.
2Reliability
If sensors are secured firmly in the tire contact area, then tire information can be relayed reliably, but dismounting becomes difficult and non-reproducible
Solution Approach 1:
The receiving area is divided into a first part (secured to the tire) and a second part (containing the sensor). The predetermined breaking point between these parts allows the second part to be separated cleanly, enabling easy and reproducible sensor dismounting while maintaining firm initial mounting.
Solution Approach 2:
The second part of the receiving area is designed to be extractable from the first part through the predetermined breaking point. This extraction mechanism allows the sensor to be released without affecting the first part that remains secured in the tire, solving the contradiction between firm mounting and easy dismounting.
3Adaptability or versatility
If the sensor housing is designed for reuse, then resource efficiency improves, but improper reuse may occur without standardized destruction
Solution Approach 1:
The predetermined breaking point is pre-formed during manufacturing, creating a controlled separation path. This allows the housing to be cleanly separated into reusable parts when needed, while also enabling standardized destruction procedures by eliminating the need for ad-hoc tool-based removal that causes damage and variability.

AI summary
A sensor housing for mounting in a vehicle wheel, preferably a motor vehicle wheel and preferably on an inside of a tire of the wheel, is provided. The sensor housing includes a base surface for securing the sensor housing in the inner chamber of a wheel, a receiving area having a recess for receiving a sensor, and a predetermined breaking point for breaking open the receiving area and thus for releasing the sensor from the receiving area, preferably in a manner that prevents reuse of the sensor housing. A sensor arrangement including the sensor housing and a sensor received therein is also provided.
