Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wires are connected to transmit various signals to the control device, then the control device can receive all necessary signals, but the wiring becomes complicated and difficult to manage
Solution Approach 1:
The patent combines multiple signal transmission functions into a single cable. The cable includes multiple conductors that can transmit command signals, video signals, and switch signals simultaneously, replacing what would traditionally require multiple separate cables. This merging approach reduces wiring complexity while maintaining full signal transmission capability.
Solution Approach 2:
The single cable is designed with multi-functionality to handle various types of signals. It can transmit command signals from the display input device, video signals from the control device, and switch signals from switches, all through the same physical medium. This universal cable design eliminates the need for separate dedicated cables for each signal type.
2Reliability
If multiple cables are used to transmit different signals, then signal transmission is reliable and dedicated, but the number of cables increases and wiring becomes complex
Solution Approach 1:
Multiple signal transmission functions are merged into a single cable with multiple conductors. Each conductor can be dedicated to specific signal types while being physically integrated in one cable, maintaining signal transmission reliability while improving wiring management ease.
Solution Approach 2:
The cable is segmented into multiple conductors or regions, where different regions can transmit different signal types. This segmentation within the unified cable structure allows for reliable dedicated signal paths while keeping the overall wiring simple and manageable.
3Ease of manufacture
If display input device and switch are disposed separately, then each component can be optimized independently, but the overall device size increases
Solution Approach 1:
The display input device and switch are disposed adjacent to each other in an integrated arrangement. They share common components such as the cable connection and housing space, reducing the overall device volume while allowing each component to maintain its functional independence and optimization.
Solution Approach 2:
The switch is disposed within or adjacent to the display input device structure, utilizing the same spatial envelope. This nested or closely integrated arrangement allows both components to coexist in a compact configuration without interfering with each other's independent optimization.

AI summary
A technique capable of reducing wiring is provided. The mounting apparatus includes a display input device capable of displaying an image of multiple selection items for controlling the operation of the mounting apparatus and for inputting commands for selecting any selection item from the multiple displayed selection items, a control device, and a single cable connecting the display input device and the control device. When a command for selecting the selection item is inputted, the display input device transmits a command signal corresponding to the inputted command to the control device via the cable. In addition to transmitting a video signal for displaying the multiple selection items to the display input device via the cable, the control device updates the video signal based on the command signal received from the display input device and transmits the updated video signal to the display input device.
