Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing wireless input devices are used to control audiovisual functions, then the device can be operated wirelessly, but the switches lack sufficient visual and tactile differentiation leading to user errors
Solution Approach 1:
The patent applies local quality by giving each switch unique visual and tactile characteristics. The first switch has a first visual indicator and first tactile feature, while the second switch has a second visual indicator and second tactile feature. This differentiation ensures users can easily distinguish between switches without confusion, preventing accidental wrong activations while maintaining wireless operation convenience.
Solution Approach 2:
The patent utilizes color changes as visual indicators to differentiate between switches. Each switch is associated with a distinct color that provides immediate visual feedback to users, enabling quick and accurate identification of the correct switch for microphone or video control, thereby eliminating user errors in wireless operation.
2Reliability
If specialized physical input devices with switches are used to control microphone and camera functions, then user feedback is improved, but software installation or device drivers are required which many users cannot install due to security policies
Solution Approach 1:
The patent implements self-service by designing a system where the audiovisual application itself provides the feedback mechanism. When the application detects a control signal from the wireless input device, it automatically changes its graphical user interface to reflect the new audio/video status. This eliminates the need for separate driver software or system administrator intervention, as the application serves its own feedback needs.
Solution Approach 2:
The patent applies universality by making the wireless input device compatible with any audiovisual application that responds to standard control signals. The device uses conventional signaling methods that can be interpreted by multiple applications, allowing it to provide reliable user feedback across different software platforms without requiring application-specific drivers or configuration.
3Stability of the object's composition
If existing devices with wired interfaces are used to communicate with computers, then connection stability is ensured, but the convenience and advantages of cable-free operation are lost
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The wireless input device transmits control signals and receives feedback through wireless communication protocols, eliminating the need for physical cables. This substitution maintains connection stability through reliable wireless protocols while providing the operational convenience of cable-free movement and positioning.

AI summary
An audiovisual controller adapted to transmit control signals to a computing device for controlling microphone and video functions of an audiovisual application executed on the computing device. The audiovisual controller has a housing with a first portion having a first switch and a second portion having a second switch. The first switch and the second switch are each associated with either the microphone or video function of the audiovisual application. The first portion and the first switch are enlarged compared to the second portion and the second switch, and provide visual and tactile differentiation to prevent a user from misidentifying or unintentionally activating the incorrect switch. Each switch further has an illumination element which emits light in accordance with a plurality of illumination states, and activation of the switch causes the illumination element to alternate between the illumination states.
