Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external speakers are connected to television by wires, then sound quality and surround sound system are improved, but installation complexity and interior design degradation increase
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless transmission system. The television outputs audio signals wirelessly to external speakers, eliminating the need for physical cables while maintaining surround sound quality. This substitution resolves the contradiction by removing installation complexity and interior design degradation while preserving sound quality.
Solution Approach 2:
The patent introduces a wireless transmission mechanism as an intermediary between the television and external speakers. This intermediary enables audio signal transmission without direct physical connection, allowing flexible installation while maintaining sound quality. The wireless transmission acts as the mediator that resolves the contradiction between connection reliability and installation simplicity.
2Reliability
If wired connections are used for external speakers, then audio signal transmission is stable, but flexibility and ease of reconfiguration are reduced
Solution Approach 1:
The patent replaces the rigid mechanical cable connection with wireless signal transmission. This allows external speakers to be positioned flexibly without cable constraints while maintaining stable audio signal transmission through wireless protocols. The substitution enables reconfiguration and movement of speakers without physical connection limitations.
Solution Approach 2:
The patent implements a dynamic wireless connection system that allows flexible positioning and reconfiguration of external speakers. Unlike static wired connections, the wireless system enables dynamic adjustment of speaker locations and system configuration while maintaining stable audio transmission through continuous wireless signal communication.
3Adaptability or versatility
If multiple connectors are installed in television for external speakers, then surround sound output capability is improved, but device complexity and design limitation increase
Solution Approach 1:
The patent replaces multiple physical connectors with a wireless transmission interface. Instead of requiring multiple connector ports for different speaker configurations, the system uses wireless communication to provide versatile surround sound output capabilities. This eliminates connector complexity while maintaining the ability to support various speaker setups.
Solution Approach 2:
The patent implements a universal wireless transmission interface that can support multiple types of external speakers and surround sound configurations through a single interface type. This multi-functional wireless connection replaces the need for multiple dedicated connectors, reducing device complexity while maintaining versatility for different audio setups.
4Reliability
If cable connections are made for audio systems, then signal transmission is reliable, but ease of installation and modification is reduced
Solution Approach 1:
The patent substitutes mechanical cable connections with wireless signal transmission. This eliminates the need for physical cable installation and modification while maintaining reliable audio signal transmission through wireless protocols. The substitution dramatically improves installation ease while preserving signal transmission reliability.
Solution Approach 2:
The patent introduces wireless transmission as an intermediary mechanism that enables reliable signal transmission without direct physical connection. This intermediary approach allows for easy installation and modification of audio systems while maintaining signal reliability through robust wireless communication protocols.
