Tyre Device Adhesive Layout for Uniform Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching devices like RFID patches to tyres suffer from unreliable adhesion due to uneven adhesive application, excessive glue use, and time-consuming processes, leading to detachment and loss of functionality.
Innovation Solution
A method involving the application of a uniform adhesive layer to the device, using an inner portion and outer line of adhesive, spread over the device's surface to ensure a secure attachment to the tyre, with specific adhesive amounts and pressures applied to achieve a robust bond.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied to the device surface, then the device can be attached to the tyre, but the adhesive may be unevenly distributed causing unreliable attachment
Solution Approach 1:
The adhesive application process is segmented into two distinct stages: first applying adhesive to the inner portion of the device surface, then applying adhesive to the outer peripheral portion. This segmentation ensures controlled distribution and prevents uneven adhesive layers that would compromise attachment reliability.
Solution Approach 2:
The method performs preliminary adhesive application to the inner portion before applying adhesive to the outer peripheral portion. This sequential preliminary action allows the inner adhesive to begin bonding while the outer adhesive is being applied, ensuring uniform distribution and preventing adhesive overflow or uneven coverage.
2Strength
If more adhesive is used to ensure secure attachment, then bond strength improves, but adhesive waste and discharge increase
Solution Approach 1:
The adhesive application uses local quality by applying different amounts of adhesive to different regions of the device surface. The inner portion receives a controlled amount of adhesive, while the outer peripheral portion receives adhesive in a manner that prevents overflow. This localized control ensures adequate bond strength without excessive adhesive waste or discharge.
3Area of stationary object
If adhesive is applied generously to cover the device, then coverage is improved, but wrinkles and creases form in the device
Solution Approach 1:
The adhesive application is segmented into inner portion and outer peripheral portion applications. This segmentation allows the adhesive to be applied in controlled increments, ensuring complete coverage of the device surface while preventing excessive adhesive accumulation that would cause wrinkles or creases in the device material.
4Device complexity
If manual adhesive application is used to reduce equipment cost, then equipment complexity decreases, but application time increases
Solution Approach 1:
The method employs self-service principles where the adhesive application process is designed to be self-regulating. The adhesive is applied in a manner that allows it to naturally distribute and bond without requiring complex automated equipment or prolonged manual application, thus reducing both equipment complexity and application time.
