Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection device is provided between the control device and the image display device to enable control of various image display devices, then the control device can control various image display devices, but an extra device is necessary which increases device complexity
Solution Approach 1:
The patent extracts the control form specifications from the image display device and stores them in a separate storage unit within the control device. This eliminates the need for a connection device by having the control device independently acquire and store individual information (control forms) for multiple image display devices, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The control device is designed with multi-functionality to control different types of image display devices (head-mounted displays, projection displays, navigation displays) by storing and switching between multiple control forms. The single control device can adapt to various devices without requiring additional connection devices, achieving universality without increasing complexity
2Adaptability or versatility
If connection control is performed for control devices and image display devices to handle different models, then various image display devices can be controlled, but the configurations and control become complicated
Solution Approach 1:
The control device acquires and stores control forms for multiple image display devices in advance in its storage unit. When a user wants to control a specific device, the control device simply switches to the pre-stored control form corresponding to that device, eliminating the need for complex real-time connection control and configuration adjustments
Solution Approach 2:
The storage unit acts as an intermediary between the control device and multiple image display devices. It stores the control forms that mediate the communication between the control device and different device types, simplifying the control process by providing pre-configured parameters without requiring complex real-time negotiation
3Ease of operation
If users select arbitrary sets of control devices and image display devices to improve convenience, then user flexibility is improved, but control deficiencies occur when image display control conditions differ between models
Solution Approach 1:
The control device stores different control forms with varying parameters (resolution, frame rate, pixel arrangement, scan direction, gamma value) for different image display device models. When controlling a specific device, the control device changes its operating parameters to match the stored control form for that device type, ensuring reliable control while allowing users flexible device selection
Solution Approach 2:
The control forms for different device models are prepared in advance and stored in the control device. This preliminary preparation ensures that when users connect any image display device, the control device already has the appropriate control parameters ready, preventing control deficiencies and ensuring reliability across all device combinations

AI summary
A control device that controls an image display device that forms an image on the basis of an image signal includes: an acquiring unit that acquires, from the image display device, individual information for specifying a control form of the image display device connected to the control device; and a control unit that controls the image display device on the basis of the acquired individual information.
