Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a mechanical two-stage pressing switch is used for controlling the X-ray source, then the device structure is simple, but the operation complexity increases and functionality is limited
Solution Approach 1:
The patent replaces the traditional mechanical two-stage pressing switch with a wireless remote exposure control device that uses touch sensors, acceleration sensors, and wireless communication modules. This substitution eliminates the need for mechanical contact, reduces operational complexity, and enables multiple control modes including gesture recognition and one-button exposure, directly resolving the contradiction between simple structure and ease of operation.
Solution Approach 2:
The wireless remote exposure control device integrates multiple functions including touch sensing, acceleration sensing, wireless communication, gesture recognition, and environmental monitoring into a single device. This multi-functionality allows the device to serve as both a simple remote control and an intelligent control system, reducing operation complexity while maintaining structural efficiency.
2Ease of operation
If a wireless remote control device with multiple modules is used, then the functionality and ease of operation are improved, but the device complexity increases
Solution Approach 1:
The patent combines power source module, processing module, communication module, sensing module, and audio module into an integrated wireless remote exposure control device. This merging of multiple functional modules into a single unified device improves control efficiency and user experience while managing device complexity through systematic integration rather than separate components.
Solution Approach 2:
The device incorporates environmental sensors (temperature, humidity) that automatically monitor and report device status without user intervention. The acceleration sensor enables automatic gesture recognition and trigger signal generation, reducing the need for complex manual operations and simplifying the user interface despite the presence of multiple internal modules.
3Use of energy by moving object
If the pairing device remains in sleeping or power-off state, then the energy consumption is reduced, but the response time for exposure increases
Solution Approach 1:
The wireless remote exposure control device can send wake-up signals to the pairing device before the actual exposure is needed. This preliminary action allows the pairing device to transition from sleeping or power-off state to active state in advance, ensuring rapid response time when exposure is required while minimizing energy consumption during idle periods.
Solution Approach 2:
The device includes state information output functionality that provides feedback about the pairing device's current state (sleeping, power-off, or active). This feedback mechanism allows the system to intelligently manage power states and response timing, balancing energy consumption with response time requirements based on operational context.
