Transponder Fixation in Blind Bore via Sealing Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing a transponder in a blind hole are complex and costly, often requiring multiple parts and assembly steps, which complicates the process and increases material usage.
Innovation Solution
A transponder is encased in a shell made of elastomer, silicone, or plastic, with a circumferential projection at the blind hole's mouth that is bent to securely fix the transponder in a form-fitting manner, eliminating the need for additional parts and complex assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping elements and sealing elements are used to fix the transponder in the blind hole, then the transponder is securely fixed, but the device becomes complicated and expensive due to the large number of parts required
Solution Approach 1:
The patent integrates the fixation function and sealing function into a single integrated sealing cap that closes the blind hole. This eliminates the need for separate clamping elements and sealing elements, reducing the number of parts while maintaining secure fixation and sealing of the transponder in the blind hole
2Reliability
If multiple parts and assembly steps are used to fix the transponder, then reliable fixation is achieved, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The sealing cap is pre-formed with an integrated sealing structure and fixation features. The transponder is inserted into the blind hole and the sealing cap is then closed in a single operation, eliminating the need for multiple assembly steps. The preliminary design of the integrated cap structure simplifies the manufacturing process while ensuring reliable fixation
3Reliability
If additional parts are used for transponder fixation, then secure mounting is achieved, but material usage and cost increase
Solution Approach 1:
The sealing cap combines multiple functions (sealing, fixation, and protection) into a single component made from a single material structure. This eliminates the need for additional clamping elements and separate sealing elements, reducing material usage and overall cost while maintaining secure mounting of the transponder

AI summary
Proposed is a device (100), for example a field instrument or valve, having a blind bore for the introduction of a transponder (110), wherein the transponder (110) is surrounded by a casing (120) composed for example of a thermoplastic synthetic material, and wherein the casing (120) is designed to be suitable for fixing the transponder (110) in the blind bore. The fixing of the transponder (110) in the blind bore is in this case particularly easy, without the need for additional parts or cumbersome installation steps.
