The wireless transmitting module and wireless receiving module enable cable-free transmission of multimedia data, eliminating the need for physical connectors and cables while maintaining transmission stability through protocol-based error correction and acknowledgment mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If wired transmission methods (D-sub, DVI, HDMI) are used for multimedia data transmission, then transmission stability and reliability are improved, but cost increases

Engineering Contradiction:

Improvetransmission stabilityVSAvoidcost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent substitutes expensive wired transmission interfaces (DVI, HDMI cables and connectors) with a wireless UWB transmission system. This eliminates the need for costly high-speed cables and specialized connectors, reducing material costs while maintaining transmission quality through software-based error handling and protocol optimization.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If wireless transmission is implemented, then convenience and cost are improved, but transmission quality may deteriorate

Engineering Contradiction:

ImproveconvenienceVSAvoidtransmission quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The wireless receiving module sends acknowledgment packets back to the transmitting module to confirm successful data reception. This feedback mechanism enables error detection and retransmission of corrupted or lost data packets, ensuring transmission quality is maintained despite the wireless medium's susceptibility to interference and signal degradation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system implements error correction codes and redundancy mechanisms in advance of potential transmission errors. By preparing correction data and retransmission protocols beforehand, the system can compensate for wireless transmission imperfections and maintain high-quality multimedia data delivery without requiring perfect signal conditions.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
