Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellulose-based films are exposed to various conditions for application use, then the films can perform their intended functions, but the films suffer adverse effects from environmental conditions that go undetected
Solution Approach 1:
The patent incorporates an optical sensor system that proactively monitors the cellulose-based film for modifications before they compromise product quality. The sensor detects changes in the film's optical properties caused by environmental exposure, enabling early intervention and maintaining reliability while the film performs its application functions.
Solution Approach 2:
The patent implements a feedback mechanism where the optical sensor continuously monitors the film's condition and provides information about environmental exposure effects. This feedback loop enables real-time quality assurance, allowing the system to detect and respond to adverse conditions while the film is in use, thus maintaining both versatility and reliability.
2Object-affected harmful factors
If the cellulose-based film is made transparent and biodegradable for environmental benefits, then the film is eco-friendly, but the film cannot detect environmental conditions that affect it
Solution Approach 1:
The patent introduces an optical sensor as an intermediary element that detects environmental effects on the cellulose-based film. The sensor acts as a mediator between the film and the monitoring system, enabling detection of modifications without compromising the film's transparency and biodegradability. The sensor converts physical/chemical changes in the film into detectable optical signals.
3Measurement precision
If an optical sensor system is implemented to detect film modifications, then product quality can be monitored, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with an optical sensor-based detection system. By using optical properties to detect film modifications, the system achieves high measurement precision while avoiding the complexity of mechanical sensors, moving parts, and associated control mechanisms.
