Tamper Seal Assembly With Destructive Form-Fit Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tamper protection systems for objects like pulse generators in commercial vehicles are complex to install and maintain, and they often require force-fitting connections that are difficult to manufacture and may not provide secure protection against manipulation or unauthorized removal.
Innovation Solution
A tamper protection device with a positive connection between two cylindrical parts that can only be separated by destroying the connection, featuring a form-fitting design with radially deflectable spring elements and anti-twist mechanisms, allowing easy assembly and secure attachment to cylindrical objects, while preventing axial movement and rotation of the object to be protected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire-bound seal is used to prevent tampering with the pulse generator, then manipulation protection is provided, but the installation becomes complex and time-consuming due to threading wire through multiple openings and connecting wire ends
Solution Approach 1:
The tamper protection device is divided into two separate parts: a first part that receives the object to be protected and a second part that connects to the object. This segmentation eliminates the need for complex wire threading through multiple openings, as the form-fit connection is established simply by bringing the two parts together in their final positions.
2Reliability
If a wire-bound seal is used to prevent unauthorized removal, then security is improved, but the installation process becomes more difficult and requires precise threading and connection
Solution Approach 1:
The form-fit connection elements are pre-formed and integrated into the two parts of the tamper protection device during manufacturing. This preliminary preparation eliminates the need for complex field assembly operations such as threading wire through openings and making precise connections, allowing installers to simply position and connect the two parts.
3Reliability
If a non-detachable form-fit connection is used, then tamper protection reliability is enhanced, but the ability to detach and reuse the device is reduced
Solution Approach 1:
The tamper protection device is designed as a disposable security element where the form-fit connection is intentionally made non-detachable without destruction. The device fulfills its security function and is then discarded, eliminating the need for complex detachable mechanisms while maintaining high reliability for tamper protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, easy-to-install tamper protection system that prevents manipulation and unauthorized removal of objects by ensuring the connection can only be broken by destruction, simplifying assembly and maintaining the object's integrity through rotatability and electromagnetic shielding.
Implementation Method 1
The connection is essentially made by inserting the second part into the first part or screwing the second part into the first part
