Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If real-time image transmission is performed between multiple information processing devices using wireless communication, then image data can be exchanged without wired connections, but user manipulability deteriorates when multiple sink devices are involved

Engineering Contradiction:
Improvewireless communication capabilityVSAvoiduser manipulability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a control unit as an intermediary that manages multiple sink devices and their corresponding UIBCs. This control unit receives control information from sink devices and performs centralized on-off switching of UIBCs, thereby mediating between the wireless communication capability and user manipulability. The intermediary handles the complexity of managing multiple devices, allowing users to interact with a single control point rather than managing each device individually.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple sink devices are connected for real-time image transmission, then system versatility is improved, but control complexity increases due to multiple UIBCs

Engineering Contradiction:
Improvemulti-device connection capabilityVSAvoidcontrol information management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the control functions for multiple UIBCs into a single control unit. Instead of managing each UIBC independently across multiple sink devices, the control unit consolidates the on-off switching control for all UIBCs, receiving control information from sink devices and performing unified management. This merging reduces control complexity while maintaining multi-device connection capability.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If UIBC is enabled for all sink devices, then user input capability is maximized, but system reliability decreases due to potential conflicts from multiple control channels

Engineering Contradiction:
Improveuser input capabilityVSAvoidcontrol stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements dynamic on-off switching of UIBCs based on received control information. Rather than statically enabling or disabling UIBCs, the system dynamically adjusts which UIBCs are active according to the control information received from sink devices. This dynamic approach allows the system to maximize user input capability when needed while maintaining control stability by selectively activating only necessary control channels.

Inventive Principle:
Principle #15Dynamics
