Monobloc Elastomer Profile for Precise Electronic Module Encapsulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for coating electronic devices in semi-finished articles, such as tires, require precise alignment and synchronization of rubber strips to ensure proper coverage, which can be cumbersome and inefficient.
Innovation Solution
A one-piece profiled strip made of elastomeric material with a reception area and a deformable flap is used to coat electronic devices, allowing for precise positioning and complete coverage without the need for complex alignment, using an application force to plastically deform the flap and embed the device in the rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple rubber strips are used to coat the electronic device, then complete coverage is achieved, but alignment and synchronization complexity increases
Solution Approach 1:
The patent merges multiple rubber strips into a single monobloc profile that integrates multiple coating functions. The monobloc profile includes a first rubber strip portion and a second rubber strip portion that are structurally integrated rather than separate, eliminating the need for alignment and synchronization between multiple strips while maintaining complete coverage of the electronic device.
2Strength
If rubber strips are used with high dielectric constant, then mechanical strength is improved, but signal transmission quality deteriorates
Solution Approach 1:
The patent applies local quality by creating a pre-coating layer with different material properties than the main rubber structure. The pre-coating layer has low dielectric constant to protect signal transmission, while the main monobloc profile provides mechanical strength. This allows different regions of the rubber structure to have optimized properties for their specific functions.

Function Achieved in This Case
This method simplifies the coating process by ensuring complete coverage of electronic devices with minimal manual intervention, improving efficiency and reducing the risk of misalignment while maintaining a low dielectric constant for effective signal transmission.
Implementation Method 1
capable of being plastically deformed by application of an application force in a predetermined direction so as to enclose the electronic device
Implementation Method 2
the higher the dielectric constant of the rubber coating the electronic device, the more the electrical signal received and transmitted by the device is attenuated
