Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If only one charging method (wired or wireless) is supported, then device complexity is reduced, but charging time increases and productivity decreases

Engineering Contradiction:
Improvecharging speedVSAvoidcharging path control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic charging path control where the controller automatically switches between wired charging path, wireless charging path, and simultaneous dual charging path based on real-time detection of charging cable connection status and power source availability. This dynamic adaptation allows the system to optimize charging speed by utilizing both charging methods simultaneously when conditions permit, while simplifying to single method operation when necessary, thereby resolving the contradiction between charging productivity and device complexity.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If simultaneous wired and wireless charging is implemented, then charging time is reduced, but device complexity and control difficulty increase

Engineering Contradiction:
Improvecharging timeVSAvoidcharging path control structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent employs feedback-based control where the controller continuously monitors the connection status of charging cables and the availability of power sources, then automatically adjusts the charging path configuration. When both wired and wireless power sources are detected as available, the system activates simultaneous dual charging path operation to minimize charging time. The feedback mechanism ensures that the system transitions smoothly between different charging modes without requiring complex manual intervention, thus reducing charging time while managing control complexity through automated decision-making.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple charging paths are available, then adaptability and versatility improve, but control difficulty and system complexity increase

Engineering Contradiction:
Improvecharging method flexibilityVSAvoidcharging path control ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements self-service charging path control where the system automatically detects the user's charging needs based on cable connection status and power source availability, then autonomously selects and configures the appropriate charging path. Users simply need to connect their preferred charging method (wired or wireless), and the controller automatically determines whether to activate single or dual charging paths without requiring users to manually configure complex settings. This self-service approach enhances adaptability to different charging scenarios while maintaining ease of operation by eliminating the need for users to understand or control the underlying path selection logic.

Inventive Principle:
Principle #25Self-service
