Innovation Solution
An audio system with wireless communication units using NFC or infrared technology allows adjustment parameters to be set remotely via a portable device, eliminating the need for physical access and expert intervention, and includes memory units for parameter storage and control units for automated setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diffusers are positioned vertically in line (line array configuration), then sound diffusion coverage is improved, but accessibility for configuration becomes difficult requiring ladders
Solution Approach 1:
The patent replaces the mechanical approach of physical access via ladders with a wireless communication system. The control unit communicates adjustment parameters wirelessly to the diffusers, eliminating the need for technicians to physically reach suspended diffusers while maintaining full configuration capability.
Solution Approach 2:
The patent introduces a wireless communication unit as an intermediary between the technician and the suspended diffusers. This intermediary transmits control signals and receives status information without requiring direct physical contact, solving the accessibility problem while preserving adaptability.
2Ease of operation
If panels are exposed to outdoor environments, then ease of access is improved, but reliability decreases due to weather exposure
Solution Approach 1:
The patent replaces physical panel access with wireless communication, allowing configuration without exposing control panels to outdoor weather. The wireless system can operate from protected locations while still controlling suspended diffusers, maintaining both accessibility and reliability.
3Ease of operation
If centralized control system is implemented, then ease of operation is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces wired centralized control with wireless communication technology. This eliminates complex wiring infrastructure while maintaining the ease of operation benefit, as the wireless system provides similar control capabilities without the mechanical complexity of extensive cable routing.
Solution Approach 2:
The patent extracts the communication function from the physical wiring infrastructure. By using wireless technology, the control system operates independently of complex cable connections, reducing device complexity while preserving operational ease.
4Reliability
If expert personnel are required for configuration, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables the audio system to be configured by end-users through wireless communication interfaces. The system provides user-friendly interaction methods that do not require expert knowledge, while maintaining reliable configuration through automated parameter transmission and wireless control capabilities.
