Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a replaceable power supply is used in the fuel dispensing nozzle, then the electronic device can be powered, but the risk of tampering and internal damage increases, introducing additional risk of electrical shorts and sparks
Solution Approach 1:
The fuel dispensing nozzle charges its own electronic device battery through wireless energy transfer from the fuel nozzle housing, eliminating the need for external power sources or user intervention. The system automatically detects when the nozzle is docked and initiates charging without user action, making the power supply process self-service and eliminating tampering risks associated with replaceable batteries
2Reliability
If a rechargeable power supply is used to avoid replacement, then tampering risk is reduced, but charging time becomes a critical factor that must be sufficiently quick for peak usage periods
Solution Approach 1:
The wireless charging system operates continuously whenever the fuel dispensing nozzle is docked in the fuel nozzle housing, maximizing charging time utilization. The charging process is not interrupted by usage patterns and occurs automatically during all docking periods, including off-peak times, ensuring the battery is continuously recharged without wasting available charging opportunities
Solution Approach 2:
The system performs charging actions in advance during off-peak periods and between uses, ensuring the battery is fully charged before the next customer arrival. By charging continuously during all available docking time, the system prepares the power supply in advance for peak usage periods, eliminating charging delays during critical service times
3Ease of operation
If the wireless energy transmitting component is arranged inside the cradle, then the arrangement is convenient, but the energy transmission area is restricted to a point-source
Solution Approach 1:
The wireless energy transmitting component is moved from a two-dimensional plane inside the cradle to a three-dimensional protruding wall structure that extends outward. This dimensional change allows the transmitting component to occupy a larger spatial volume and provide energy transmission over a broader area, transforming the point-source limitation into a distributed energy field that covers the entire docking surface
4Productivity
If a larger energy transmission area is obtained, then charge times are shortened and power storage is increased, but the device complexity increases with multiple components
Solution Approach 1:
Multiple wireless energy transmitting components are integrated into a single unified fuel nozzle housing structure, merging separate charging elements into one cohesive system. The protruding wall design consolidates the transmitting components and their support structures into a single architectural feature, reducing overall device complexity while maintaining the benefits of distributed energy transmission across multiple contact points
