Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stationary charging locations with AC power outlets are used, then reliable charging is ensured, but accessibility and convenience deteriorate because outlets are not always available

Engineering Contradiction:

Improvecharging reliabilityVSAvoidcharging accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent transforms the static charging infrastructure into a dynamic system where any mobile device can become a charging station. Donor devices dynamically register their charging capabilities with the network, and requesting devices can dynamically discover and connect to available charging sources anywhere in the network, eliminating the constraint of fixed charging locations.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables mobile devices to serve multiple functions: they can be both power consumers and power donors. Any battery-operated radio equipment can register as a charging station when its battery charge level exceeds a threshold, allowing devices to universally provide charging services throughout the network.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If wireless charging is implemented without a structured system, then convenience is improved, but system complexity and management difficulty increase

Engineering Contradiction:

Improvecharging convenienceVSAvoidsystem management complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a network controller as an intermediary that manages the wireless charging system. The controller receives registration messages from donor devices, processes charging requests from requesting devices, matches donors with requesters, and handles payment transactions, thereby simplifying the overall system management.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms where donor devices report their battery charge levels to the network controller, and the controller provides feedback about charging requests and system status. This feedback loop enables automated decision-making for charge level thresholds, donor selection, and payment processing.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If multiple donor nodes are registered, then charging availability is improved, but selection and coordination difficulty increases

Engineering Contradiction:

Improvecharging availabilityVSAvoiddonor selection difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent replaces manual or heuristic donor selection with an automated electronic system. The network controller automatically receives registration messages from multiple donor devices, stores their capabilities and locations, and algorithmically selects appropriate donors based on request parameters, eliminating the need for manual selection or complex device-to-device negotiation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
