Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless transmission is implemented, then cable-free interconnection and flexibility are improved, but transmission quality and stability deteriorate due to interference

Engineering Contradiction:
Improvecable-free interconnectionVSAvoidtransmission stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses RF shields and filters as intermediary components to block electromagnetic interference from reaching the wireless transmission path. These shields act as mediators between the interference sources and the transmission system, preventing harmful signals from degrading the wireless connection quality while maintaining cable-free operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful effect of electromagnetic interference into a beneficial filtering mechanism. By strategically placing RF shields and filters, the system uses the presence of interference to drive the development of more effective shielding and filtering solutions, ultimately improving transmission reliability through these protective measures.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Adaptability or versatility

If integrated transmitters and receivers are added to devices, then interconnection capability is improved, but device complexity increases

Engineering Contradiction:
Improveinterconnection capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universal RF transmitter and receiver modules that can be integrated into multiple types of consumer electronics devices. These multi-functional modules enable different devices (televisions, audio equipment, computing devices) to interconnect wirelessly using the same standardized interface, reducing the need for device-specific customization and managing complexity through standardization.

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

Solution Approach 2:

The patent combines the RF transmitter and receiver functionality into integrated modules that can be added to existing devices without requiring complete redesign. By merging these wireless communication capabilities with standard device architectures and using common power and signal interfaces, the system reduces overall complexity compared to implementing separate wireless systems for each device type.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If RF shields and filters are installed, then interference resistance is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveinterference resistanceVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent divides the interference protection system into separate, modular RF shields and filters that can be manufactured independently and then assembled into the final device. This segmentation allows each component to be optimized and manufactured using specialized processes, then integrated into the device through standardized mounting procedures, reducing overall manufacturing complexity despite adding protection capabilities.

Inventive Principle:
Principle #1Segmentation
