Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If heating is applied to enlarge the inner diameter of the braid, then the water permeability is improved, but the temperature becomes unstable due to seasonal and time zone factors, leading to inconsistent physical properties
Solution Approach 1:
The patent employs a temperature sensor to detect the actual temperature of the heating core and feeds this information back to a controller. The controller adjusts the heating power accordingly to maintain a stable target temperature, compensating for seasonal and environmental variations. This closed-loop feedback system ensures consistent heating temperature regardless of external conditions.
Solution Approach 2:
The patent changes the physical state of the heating core from unstable temperature fluctuation to stable controlled temperature by introducing active temperature regulation. The system dynamically adjusts heating parameters (power, duration) based on real-time temperature measurements to maintain optimal heating conditions for enlarging the braid's inner diameter while ensuring consistent physical properties.
2Stability of the object's composition
If heating core is used to maintain uniform temperature, then the physical properties are improved, but heat loss occurs to the clamping nut, creating safety hazards
Solution Approach 1:
The patent introduces a heat shield tube as an intermediary component between the heating core and the clamping nut. This heat shield acts as a thermal barrier that prevents direct heat transfer to the clamping nut, reducing heat loss and eliminating the burn hazard while allowing the heating core to maintain its uniform temperature for consistent braid physical properties.
Solution Approach 2:
The patent converts the potential harmful effect of heat generation into a beneficial controlled heating process. By using the temperature sensor and controller to precisely manage the heating core's temperature, the system ensures that heat is applied uniformly and controllably to improve physical properties, while the heat shield prevents excessive heat from reaching the clamping nut, turning a safety hazard into a controlled and safe process.
