Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pre-Opened Pre-Positioned (POPP) clamps used in automotive applications often fail to release successfully, leading to inadequate clamping and potential leaks, and manual recording of clamp releases is time-consuming and prone to errors, affecting production line efficiency and quality control.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual recording of clamp releases is used, then traceability is achieved, but production line efficiency deteriorates due to time-consuming operations
Solution Approach 1:
The patent replaces manual recording operations with an automated electronic detection system. The tool head incorporates sensors and processing electronics that automatically detect clamp release events and record data, eliminating the need for manual observation and recording by operators. This substitution of mechanical/manual processes with electronic automation resolves the contradiction by maintaining traceability while dramatically improving production line efficiency.
Solution Approach 2:
The clamp release detection system is self-activating and self-recording. When a clamp release event occurs, the system automatically detects the characteristic movement pattern, triggers data recording, and stores the information without requiring operator intervention. This self-service capability ensures reliable traceability while freeing operators to focus on other value-added tasks, thereby improving overall productivity.
2Reliability
If manual checking of clamp releases is performed, then detection of unsuccessful releases is improved, but operator time and productivity deteriorate
Solution Approach 1:
The system provides immediate feedback on clamp release success by automatically detecting the characteristic movement pattern that occurs when a clamp successfully releases. The processing electronics analyze the detected movements in real-time and can provide instant confirmation or alert operators to unsuccessful releases, eliminating the need for manual checking and ensuring no leaks are missed.
Solution Approach 2:
Manual visual inspection and physical checking of clamp releases is replaced with automated electronic detection. The tool head sensors continuously monitor for the specific movement patterns associated with successful clamp release, providing reliable detection without requiring operator time for manual verification of each clamp.
3Measurement precision
If frequency content analysis is used to determine clamp closure, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent employs electronic signal processing to analyze the frequency content of detected movements. The processing electronics perform spectral analysis on the movement signals to identify characteristic frequency patterns that indicate successful clamp release. This electronic approach provides high measurement precision while keeping the device relatively simple by using standard signal processing techniques rather than complex mechanical measurement systems.
Solution Approach 2:
The system transforms the physical movement of the clamp release tool into electrical signals and then analyzes the frequency domain characteristics of these signals. By changing from direct mechanical measurement to electronic signal analysis in the frequency domain, the system achieves high detection accuracy while maintaining manageable device complexity through the use of standard electronic processing components.

AI summary
A method of operating a pre-opened pre-positioned clamp, the clamp being operable between an open and a closed position. The method comprises releasing the clamp from the open position using a tool head (201), making measurements of a movement of the tool head resulting from the releasing, recording data relating to the measurements, determining a frequency content of the data, and, on the basis of the determined frequency content, determining whether the clamp has moved to the closed position.
