Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the injector unit is pressed onto the repair area with high contact pressure to ensure proper sealing and agent application, then the sealing quality improves, but the risk of causing further damage to the glass pane increases
Solution Approach 1:
The patent employs a sensor device that provides real-time feedback on the contact pressure applied by the injector unit to the repair area. This feedback mechanism allows the system to monitor and adjust the pressure dynamically, ensuring optimal sealing quality while preventing excessive pressure that could cause further glass damage. The control unit processes sensor signals to maintain pressure within safe and effective ranges.
2Reliability
If the contact pressure is increased to prevent resin leakage, then the sealing improves, but the filling efficiency and bubble removal capability decrease
Solution Approach 1:
The patent incorporates a vibration device that applies mechanical vibrations to the injector unit or repair area during the resin filling process. These vibrations enhance the filling efficiency by promoting complete penetration of repair agent into the damaged spot and facilitating bubble removal, while the feedback-controlled pressure system maintains adequate sealing to prevent leakage. The combination of controlled pressure and vibration resolves the contradiction between sealing quality and filling efficiency.
3Device complexity
If manual application of repair agent is used, then the device complexity is low, but the measurement precision of contact pressure and repair quality are insufficient
Solution Approach 1:
The patent replaces manual mechanical application with an automated system that uses sensor devices to measure contact pressure and a control unit to regulate the injection process. This substitution of manual operation with sensor-based feedback and automated control enables precise measurement and regulation of contact pressure, significantly improving measurement precision while maintaining manageable device complexity through integrated electronic control.
