Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual activation and deactivation of wireless chargers is used, then users can control charging operations, but energy waste increases and battery degradation occurs due to user error and lack of precision

Engineering Contradiction:
ImproveManual control of charging operationsVSAvoidEnergy waste from premature or extended charging
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The wireless charging system automatically detects the presence of game devices, determines charging state, and activates or deactivates charging circuits without user intervention. The system monitors battery status and autonomously manages the entire charging process, eliminating user error and precise timing requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors the charging state of batteries in game devices and uses this feedback to automatically control the charging circuits. The system adjusts charging operations based on real-time battery status, ensuring charging stops when batteries are fully charged and preventing energy waste.

Inventive Principle:
Principle #23Feedback

2Productivity

If wireless chargers are left in active transmitting state continuously, then charging availability is maximized, but energy consumption increases and FCC regulation compliance becomes problematic

Engineering Contradiction:
ImproveCharging availability and responsivenessVSAvoidEnergy consumption from continuous transmitting state
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The wireless charging system operates in periodic cycles, alternating between active transmitting state and standby state. The system activates the transmitting circuit only when game devices are detected in proximity, then deactivates it when devices are removed or charging is complete, creating an on-demand operation pattern that reduces energy consumption while maintaining charging availability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts its operating state based on real-time conditions. The transmitting circuit transitions between active and inactive states according to the presence and charging needs of game devices, optimizing the balance between charging availability and energy consumption rather than maintaining a fixed state.

Inventive Principle:
Principle #15Dynamics

3Extent of automation

If mechanical or optical switches are used to detect game device presence, then automatic charging activation is achieved, but manufacturing cost and system complexity increase significantly

Engineering Contradiction:
ImproveAutomatic detection and activation of chargingVSAvoidComplexity of mechanical or optical detection systems
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system replaces mechanical or optical switches with wireless communication-based detection. Game devices and charging pods use radio frequency transceivers to automatically detect each other's presence and exchange charging status information, eliminating the need for complex mechanical or optical sensing mechanisms while achieving reliable automatic charging activation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Loss of energy

If wireless charging operates over short distances without reliable communication, then charging efficiency is maintained, but communication reliability and charging management become problematic

Engineering Contradiction:
ImproveCharging efficiency and energy transferVSAvoidCommunication reliability for charging management
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The system employs a secondary Bluetooth communication channel as an intermediary for reliable data exchange between game devices and charging pods. While the primary wireless charging communication operates over short distances for energy transfer, the Bluetooth channel provides a redundant, reliable communication path for managing charging operations, confirming device presence, and exchanging status information.

Inventive Principle:
Principle #24Intermediary (Mediator)
