Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple appliances are connected to wireless power pads simultaneously, then power demand increases to meet user needs, but power distribution becomes inefficient and uncontrollable when demand exceeds supply

Engineering Contradiction:

Improveability to support multiple appliancesVSAvoidpower distribution efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments power distribution by creating isolated power zones for each pad-appliance pair. Control logic independently manages power delivery to each receiver coil based on its specific demand and priority level, preventing interference between multiple appliances and optimizing overall power distribution efficiency

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts power distribution in real-time based on changing conditions. Priority levels, power availability, and appliance states are continuously monitored and used to modify power allocation decisions, allowing the system to adapt to varying power demands while maintaining efficiency

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If power is distributed without priority management, then all appliances can operate, but user frustration increases due to lack of control over power distribution

Engineering Contradiction:

Improveuser control over power distributionVSAvoidconsistent appliance operation

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements feedback loops where appliance performance, power consumption, and priority levels are continuously monitored. This feedback enables the control logic to make informed power distribution decisions that maintain reliable operation while respecting user-defined priorities and preferences

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Each appliance autonomously communicates its power needs and operational status to the control system. The system automatically adjusts power allocation based on this self-reported information, eliminating the need for manual user intervention while maintaining user-defined priority structures

Inventive Principle:

Principle #25Self-service

3Ease of operation

If wireless power transmission is used to eliminate cords and batteries, then appliance convenience increases, but power management complexity increases when multiple devices are used simultaneously

Engineering Contradiction:

Improvewireless operation without cords or batteriesVSAvoidpower management system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system merges multiple power management functions into a unified control architecture. Priority assignment, power allocation, appliance monitoring, and communication protocols are integrated into a single coordinated system that manages all wireless appliances through centralized logic, reducing overall system complexity despite supporting multiple devices

Inventive Principle:

Principle #5Merging (Combining)
