Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated into the image-forming medium, then real-time monitoring capability is improved, but the complexity of sensor integration and power supply increases
Solution Approach 1:
The patent extracts the power supply function from the traditional wired connection and implements it as a separate wireless power transmission system. The power transmission antenna is integrated into the image-forming device, while the sensors remain attached to the image-forming medium, allowing independent optimization of each component.
Solution Approach 2:
The image-forming medium serves multiple functions: it carries the image-forming function (paper or plastic), supports sensor attachment for monitoring, and acts as a carrier for wireless power reception. This multi-functionality reduces the need for separate power supply infrastructure.
2Reliability
If wired power supply is used for sensors, then power transmission reliability is improved, but the flexibility and ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical wired power supply system with a wireless electromagnetic power transmission system. The power transmission antenna transmits power wirelessly to the power reception antenna on the image-forming medium, eliminating the need for physical connections and improving operational flexibility.
3Measurement precision
If sensors are attached to the image-forming medium, then measurement accuracy in the image-forming environment is improved, but the risk of sensor damage increases
Solution Approach 1:
The patent implements protective measures by designing the sensor attachment system to accommodate the harsh image-forming environment. The sensors are attached to the image-forming medium in a way that protects them from damage while maintaining measurement accuracy, and the wireless power system is designed to operate reliably in this environment.
4Ease of operation
If wireless power transmission is implemented, then ease of operation and flexibility are improved, but energy loss during transmission increases
Solution Approach 1:
The patent concentrates the wireless power transmission energy locally at the target area where the image-forming medium passes through the image-forming device. The power transmission antenna is positioned to create a focused electromagnetic field that efficiently transfers power to the power reception antenna on the medium, minimizing energy loss in surrounding areas.
