Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices, such as those described in Japanese Patent No. 5477308, require complex key pressing operations, making it difficult for users in environments like factories or construction sites to perform input tasks effectively due to the need for fine fingertip control.
Innovation Solution
A motion detection sensor-equipped input device that detects movements in a three-dimensional space, allowing users to input data through simple motions, with a control unit associating detected motions with control commands and a printing unit that prints based on these commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If key pressing operations are used for input, then input functionality is achieved, but operation complexity increases and ease of use deteriorates
Solution Approach 1:
The patent replaces the mechanical key pressing system with a motion detection sensor system that detects three-dimensional movements. This substitution eliminates the need for fine fingertip control and complex key operations, allowing users to input data through simple natural motions while maintaining input functionality.
Solution Approach 2:
The patent introduces three-dimensional motion detection as a new dimension for input interaction. Instead of limited two-dimensional key pressing on a keyboard, the system detects movements in three-dimensional space, providing more intuitive and easier input methods that natural human motion.
2Ease of operation
If fine key pressing operations are required, then input precision is maintained, but usability in field environments deteriorates
Solution Approach 1:
The patent replaces the mechanical key pressing system with a motion detection sensor system that detects three-dimensional movements. This substitution eliminates the need for fine fingertip control and complex key operations, allowing users to input data through simple natural motions while maintaining input functionality.
3Ease of operation
If motion detection is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The motion detection sensor serves multiple functions: it detects input motions, determines operation types based on motion patterns, and works across different environments. This multi-functionality justifies the added device complexity by providing significant improvements in ease of operation and usability.

AI summary
There is provided an input device which accepts input with a simple operation. A printing device 100 is an input device which accepts the input of input data, including a motion detection section 100a, a determination section, and an acquisition section 100d. The motion detection section 100a detects the motion of the input device. The determination section determines whether an input condition is met. When the determination section determines that the input condition is met, the acquisition section 100d acquires a trajectory of the input device based on the motion of the input device detected by the motion detection section 100a to acquire, as input data, the layout of a pattern corresponding to the trajectory.
