Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used to connect multiple microphones to a host, then reliable signal transmission is achieved, but difficulties in wiring and inflexibility in movement occur
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The microphones transmit audio signals to the host through wireless communication modules using electromagnetic waves, eliminating the need for physical cables. This substitution maintains signal transmission reliability while dramatically improving ease of operation and movement flexibility.
Solution Approach 2:
The patent introduces wireless communication modules as intermediaries between the microphones and the host. These modules include Bluetooth transceivers or Wi-Fi communication units that facilitate wireless data transmission, serving as a mediator that enables reliable communication without direct physical connections.
2Area of stationary object
If multiple extended microphones are connected to increase pick-up distance, then coverage area is improved, but wiring complexity and installation difficulty increase
Solution Approach 1:
The patent replaces the mechanical wiring system with wireless communication to extend audio coverage. Multiple microphones can be positioned throughout the conference room without being constrained by cable routing, allowing flexible placement to maximize coverage area while eliminating the complexity of managing multiple wired connections.
Solution Approach 2:
The patent enables dynamic positioning of microphones throughout the conference space. Since wireless microphones are not fixed by cables, they can be freely moved and repositioned to optimize coverage for different meeting configurations, making the system adaptable to various spatial arrangements.
