Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a button-type input sheet is used on a touch panel, then a click feeling is obtained and input accuracy is improved, but continuous operations such as rotational input cannot be performed
Solution Approach 1:
The input device is segmented into a stationary attachment mechanism (suction cup) and a movable rotational component. This allows the device to provide both stable attachment for precision and rotational freedom for continuous operations, resolving the contradiction between input accuracy and continuous operation capability
Solution Approach 2:
A rotational support body with suction cup attachment acts as an intermediary between the touch panel and the user's finger. This intermediary provides the click feeling through its structure while enabling rotational input, thus maintaining input accuracy while adding continuous operation capability
2Adaptability or versatility
If direct input on touch panel without button sheet is used, then continuous operations are possible, but input accuracy through necessary operation path deteriorates
Solution Approach 1:
The rotational support body with suction cup serves as an intermediary device that guides the user's finger along a precise rotational path while maintaining contact with the touch panel. This ensures both continuous operation capability and input accuracy through the necessary operation path
3Adaptability or versatility
If attachment mechanism is added to enable removable attachment at arbitrary positions, then adaptability is improved, but device complexity increases
Solution Approach 1:
A suction cup attachment mechanism is used to enable removable attachment at arbitrary positions on the panel surface. This pneumatic-based solution provides simple yet effective adhesion without requiring complex mechanical fastening systems, thus improving adaptability while minimizing device complexity
Solution Approach 2:
The suction cup attachment mechanism serves multiple functions: it enables removable attachment, allows positioning at arbitrary locations, and provides a stable base for rotational input. This multi-functionality improves adaptability without proportionally increasing device complexity

AI summary
[Object] To provide an input assistance device with which an input can be accurately made through a necessary path when an input involving a continuous operation such as a rotational input is necessary and that can be detachably attached at an arbitrary position on a panel surface, and to provide an input system. [Solution] The input assistance device has a rotation support body having a central axis, an attachment mechanism that removably attaches the rotation support body to the panel surface of a sensor panel so that the central axis is along a direction perpendicular to the panel surface, and a rotational part supported by the rotation support body so as to be rotatable around the central axis; at least the side surface of the rotational part is formed from a conductive material, and conductive areas electrically connected to the side surface are allocated in part of a surface of the rotational part, the surface facing the panel surface.
