Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvepower supply capabilityVSAvoidrisk of tampering and electrical shorts
Core Design Contradiction:
Use of energy by moving objectVSReliability

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvereduction of tampering riskVSAvoidcharging time between customers
Core Design Contradiction:
ReliabilityVSLoss of time

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

Inventive Principle:
Principle #20Continuity of useful action

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

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveconvenience of arrangementVSAvoidenergy transmission area
Core Design Contradiction:
Ease of operationVSArea of stationary object

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvecharging speed and power storageVSAvoidnumber of wireless energy components
Core Design Contradiction:
ProductivityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)
