Tire Electronics Attachment Carriage with Locking Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching electronics packages to the interior of a tire lack a secure and removable solution, particularly for applications involving RFID tags or pressure/temperature-sensing devices, as they often rely on unreliable fasteners or adhesives that may fail under operational stresses.
Innovation Solution
The development of a carriage-based assembly system with a locking mechanism, including a locking clip and ring, and mushroom-like clips, which securely attach an electronics package to the tire interior using a combination of through holes, pins, and elastic flanges or ramps, ensuring a stable and removable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fasteners or adhesives are used to attach electronics packages to the tire interior, then the attachment method is simple to implement, but the reliability of the attachment fails under operational stresses
Solution Approach 1:
The attachment system is divided into separate functional components: a mounting device with attachment points permanently affixed to the tire interior, a carriage with electronics package, and a locking mechanism. This segmentation allows each component to be optimized independently while working together to provide reliable attachment that can withstand operational stresses.
Solution Approach 2:
The locking mechanism incorporates dynamic elements such as elastic flanges or ramps that can deform under load and then return to their original position, allowing the attachment to accommodate operational stresses while maintaining secure connection. The locking clip can engage and disengage dynamically to secure or release the carriage.
2Reliability
If a secure locking mechanism is implemented to withstand operational stresses, then the attachment reliability improves, but the ease of operation for installation and removal decreases
Solution Approach 1:
The locking mechanism uses elastic flanges or ramps that naturally deform under insertion force and then lock automatically when the carriage is properly positioned. For removal, the locking clip can be actuated to release the engagement, allowing the carriage to be pulled off without complex tools or procedures, thus maintaining ease of operation while ensuring secure attachment during use.
Solution Approach 2:
The locking mechanism is designed to self-lock when the carriage is inserted into the mounting device, eliminating the need for additional fastening steps. The elastic elements automatically engage with the locking features, and removal is achieved by simply actuating the locking clip to release the engagement, making the system self-servicing for both installation and removal operations.
3Stability of the object's composition
If a permanent affixing method is used for the attaching device to the tire interior, then the stability of the attachment improves, but the adaptability for removing and repositioning the electronics package decreases
Solution Approach 1:
The system separates the permanently affixed mounting device from the removable carriage containing the electronics package. The mounting device with its attachment points remains stably fixed to the tire interior, while the carriage can be independently removed and repositioned by actuating the locking mechanism, thus providing both stability and adaptability through functional segmentation.
Solution Approach 2:
The locking mechanism enables dynamic transition between locked and unlocked states, allowing the carriage to be securely held in position during operation and then easily removed or repositioned when needed. This dynamic capability provides adaptability for repositioning while the permanently affixed mounting device maintains stability during the attached state.
