Solution Overview
Problem
Conventional input/output devices require a wide space for installation due to the separation of the display unit and input unit, limiting design flexibility and space efficiency.
Innovation Solution
An input/output device with an input unit located above the display surface, featuring a rotatable body with a through-hole for visibility and a signal generation unit that generates control signals based on rotation or pressure, allowing for compact integration and enhanced visibility of control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit and input unit are separated in the width direction or height direction, then the input unit can be positioned away from the display surface, but the installation space required increases
Solution Approach 1:
The input unit is merged with the display surface by positioning the input element directly above the display area. The input element includes a through-hole that allows the display to be visible through it, combining the display function and input function in the same spatial location rather than separating them horizontally or vertically
Solution Approach 2:
Instead of arranging the input unit and display unit side-by-side (width direction) or one above the other (height direction), the invention moves the input unit to a different dimensional relationship - directly above the display surface in the vertical direction, with the display visible through the input element's through-hole, creating a layered three-dimensional arrangement that saves horizontal space
2Area of stationary object
If the input unit is located above the display surface, then the installation space is minimized, but the visibility of control commands through the input unit must be enhanced
Solution Approach 1:
A window is provided in the body through-hole to enlarge the characters or symbols displayed on the projection surface. The window acts as an optical element that enhances the visibility of the display content viewed through the through-hole, compensating for the reduced direct visibility caused by the input element's position

AI summary
Disclosed is an input/output device including an output unit having a display surface, on which characters or symbols are displayed, a body rotatably provided above the display surface, a body through-hole formed in the body to allow the display surface to be visible from an outside of the body, a signal generation unit configured to generate a control signal according to whether the body is rotated, and a controller configured to control the output unit based on the control signal input from the signal generation unit.
