Flexible Receptacle for Tire-Mounted Electronic Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for fixing electronic boxes with sensors inside vehicle tires are prone to shock, temperature changes, and centrifugal forces, leading to reduced service life and potential ejection from the tire.
Innovation Solution
A device comprising a flexible receptacle fixed to the tire's internal wall with an adhesion mechanism, creating a compartment that houses the electronic box with a preformed orifice, providing a space between the box and the tire wall to isolate it from direct contact and shocks, and featuring projections and holes for reduced contact points and air passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic box is fixed directly to the internal wall of the tyre, then the fixing is simple and secure, but the box is subjected to shocks, temperature changes, and centrifugal forces that reduce its service life
Solution Approach 1:
A flexible receptacle is introduced as an intermediary element between the electronic box and the tyre internal wall. This receptacle absorbs shocks and thermal stresses, protecting the electronic box while maintaining secure fixation. The receptacle deforms elastically under centrifugal forces and impacts, preventing direct transmission of harmful factors to the box.
Solution Approach 2:
The flexible receptacle serves as a pre-established cushioning element that absorbs and dissipates shock energy before it can reach the electronic box. The material properties of the receptacle are designed to provide inherent shock absorption and thermal insulation, protecting the box from harmful factors before they cause damage.
2Reliability
If the box is fixed securely to prevent ejection, then the box remains in position under centrifugal force, but the orifices may be obstructed by material projected by centrifugal force
Solution Approach 1:
The receptacle creates a three-dimensional compartment that positions the electronic box in a specific orientation relative to the tyre wall. The orifices are oriented toward the center of the tyre rather than directly toward the tread, utilizing spatial arrangement to prevent material obstruction while maintaining secure fixation under centrifugal force.
Solution Approach 2:
The receptacle is pre-formed with a compartment that automatically orients the electronic box in the correct position during installation. This preliminary positioning ensures that the orifices face away from the tread area, preventing obstruction by centrifugally projected material while the box remains securely held in place.
3Reliability
If the box is isolated from the tyre wall to reduce thermal stress, then the service life is improved, but the fixing complexity increases
Solution Approach 1:
The receptacle is constructed from a flexible material that forms a thin-walled compartment, providing thermal and shock isolation while maintaining structural integrity. The flexibility of the shell allows it to deform with tyre movements without compromising the protection it provides to the electronic box, achieving isolation without excessive complexity.
Solution Approach 2:
The flexible receptacle serves multiple functions simultaneously: it provides shock absorption, thermal insulation, secure fixation, and proper orientation of the electronic box. By combining these functions into a single component, the solution achieves isolation from thermal stress without significantly increasing overall fixing complexity.

Function Achieved in This Case
The solution effectively prevents box rejection, reduces thermal and physical stress, and ensures accurate measurement by maintaining the box's orientation and preventing material obstruction, while allowing air and fluid discharge, thus enhancing the durability and functionality of tire parameter measurement systems.
