Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual remote controls are used for each HDMI device without CEC synchronization, then each device can be controlled independently, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The patent merges volume control functionality across multiple HDMI devices into a unified control system. The volume controller integrates with the audio generator and HDMI interface to create a centralized control mechanism that manages audio output for multiple devices simultaneously, eliminating the need for separate remote controls for each device.
Solution Approach 2:
The volume controller is designed with multi-functionality to handle volume specifications from different devices. It can acquire volume specifications from multiple sources, compute conversion ratios between different volume standards, and adjust audio signals accordingly, making a single controller universal for controlling multiple diverse devices.
2Adaptability or versatility
If volume synchronization is implemented across multiple HDMI devices, then user convenience improves, but system complexity and computational requirements increase
Solution Approach 1:
The system changes volume parameters dynamically by computing conversion ratios between different volume specifications. The volume controller adjusts audio signal parameters based on the relationship between first and second volume specifications, enabling adaptation to different device requirements while maintaining synchronization.
Solution Approach 2:
The volume controller acts as an intermediary between the audio generator and peripheral devices. It receives audio signals, applies volume adjustments based on computed conversion ratios, and transmits the adjusted signals to peripheral devices, mediating the interaction between devices with different volume specifications.
3Reliability
If volume specifications are converted between different devices, then volume synchronization is achieved, but computational overhead and processing time increase
Solution Approach 1:
The system performs preliminary actions by pre-computing and storing volume specifications and conversion ratios. The memory module stores first and second volume specifications, allowing the volume controller to quickly retrieve and apply conversion ratios without performing complex calculations in real-time, thus reducing processing delays.
