Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a battery-powered mobile radiographic image capturing apparatus is used, then portability and mobility are improved, but charging time increases and specialized charging facilities are required
Solution Approach 1:
The patent introduces a wireless power transmission system as an intermediary between the mobile radiographic apparatus and power supply infrastructure. The power transmission antenna receives power wirelessly from external transmission antennas, eliminating the need for physical battery charging and specialized charging facilities while maintaining portability.
Solution Approach 2:
The patent replaces the mechanical battery charging system with a wireless electromagnetic power transmission system. Instead of physically connecting to charging facilities or replacing heavy batteries, the system uses electromagnetic fields to transmit power wirelessly to the mobile apparatus, reducing both charging time and infrastructure requirements.
2Ease of operation
If a battery-powered mobile radiographic image capturing apparatus is used, then mobility is improved, but the system requires specialized charging facilities
Solution Approach 1:
The wireless power transmission system enables the mobile radiographic apparatus to draw power from any location with wireless power transmission infrastructure, rather than requiring specialized charging facilities. This universal power access enhances the adaptability and versatility of the system across different operational environments.
Solution Approach 2:
The wireless power transmission antenna acts as an intermediary that decouples the mobile apparatus from location-specific charging infrastructure requirements, enabling power reception from standardized transmission antennas deployed in various settings including outdoor and emergency environments.
3Use of energy by moving object
If wireless power transmission is implemented, then power consumption efficiency is improved, but system complexity increases
Solution Approach 1:
The mobile radiographic apparatus automatically manages its wireless power reception operations without requiring complex user intervention or control systems. The apparatus autonomously activates power reception when needed and manages power distribution to its components, simplifying the user interface while maintaining efficient power consumption.
