Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional power outlets and cables are used to power electronic devices, then power transfer is reliable and efficient, but cable clutter increases and mobility is limited

Engineering Contradiction:
Improvepower transfer efficiencyVSAvoidcable clutter
Core Design Contradiction:
Loss of energyVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical cable connection system with an electromagnetic field-based wireless power transfer system. The furniture component includes a power transmitter that generates an electromagnetic field to transfer power to electronic devices without physical cable connections, thereby eliminating cable clutter while maintaining power transfer capability

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

Solution Approach 2:

The patent introduces an electromagnetic field as an intermediary medium to transfer power between the furniture component and electronic devices. The power transmitter generates an electromagnetic field that acts as a mediator to convey energy wirelessly, replacing the direct mechanical cable connection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If power outlets are positioned close to furniture to avoid cable clutter, then cable management is improved, but accessibility to power is limited

Engineering Contradiction:
Improvecable managementVSAvoidpower accessibility
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The furniture component is designed with integrated wireless power transmission capability, making the furniture itself a universal power source. The power transmitter can provide power to multiple different electronic devices without requiring proximity to traditional wall outlets, enhancing both cable management and power accessibility simultaneously

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-generated harmful factors

If wireless power technology is integrated into furniture, then cable clutter is eliminated and mobility is enhanced, but device complexity increases

Engineering Contradiction:
Improvecable clutterVSAvoidfurniture component complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the power transmission functionality with the furniture structure itself. The power transmitter, control circuitry, and power source are integrated into the furniture component, merging multiple functions into a single unified system that provides wireless power without requiring separate external equipment

Inventive Principle:
Principle #5Merging (Combining)
