Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sole rotary encoder matches with multiple selective buttons to realize multiple drawing functions, then multiple drawing functions can be controlled, but the user has to remove their hand from the rotary encoder when changing functions, causing troublesome operation
Solution Approach 1:
The rotary encoder is designed to perform multiple functions by detecting different rotating directions (clockwise and counter-clockwise) and combining them with pressing operations. The same rotary encoder component handles zooming, rotating, and brush property changes without requiring additional selective buttons or encoders, thus maintaining versatility while improving ease of operation.
2Adaptability or versatility
If multiple rotary encoders are provided corresponding to multiple drawing functions, then multiple functions can be controlled simultaneously, but the device complexity increases
Solution Approach 1:
Instead of providing multiple separate rotary encoders for different drawing functions, the patent implements a single rotary encoder that can detect multiple rotating directions and combine them with pressing actions. This universal approach allows one component to replace multiple specialized components, reducing device complexity while maintaining the ability to control multiple drawing functions.
3Measurement precision
If keyboard is used to rotate the object at each 45 degrees, then rotating angle can be determined according to pressing time, but such operation is not executed easily
Solution Approach 1:
The patent replaces the keyboard-based mechanical operation with an electronic rotary encoder that directly detects rotating direction and angle. Instead of requiring users to press keyboard keys and time the presses to achieve 45-degree rotations, the rotary encoder electronically detects the rotation and automatically determines the angle, making the operation much easier while maintaining precise angle control.

AI summary
Provided is an input assistance device that generates multiple signals without removal of a hand from a rotating body. This input assistance device 10 is equipped with: an operation unit having a shaft 2 that tilts in multiple directions from a neutral position and a rotating body 3 that rotates with respect to the shaft 2; a first sensor 5 that detects the tilt direction of the shaft 2; a second sensor 6 that detects the rotational angle of the rotating body 3; and a signal generation unit 9 that generates signals using the detection result from the first sensor 5 and the detection result from the second sensor 6. Multiple signals can be generated by means of the signal generation unit 9 by selecting the type of signal on the basis of the tilt direction of the shaft 2 as detected by the first sensor 5 and adjusting the size of the signal on the basis of the rotational angle of the rotating body 3 as detected by the second sensor 6.
