Solution Overview

Problem

Character input operations in existing input devices are complex and cumbersome, making them inefficient for quick command entry.

Innovation Solution

An input device with variable operation units, including lever portions equipped with magnetic sensors, that select and switch command groups based on the operation amount, allowing for simplified command input by varying the operation position within defined ranges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple switches and operating elements are used to identify character groups and characters, then character input capability is achieved, but the operation becomes complicated

Engineering Contradiction:
Improvecharacter input capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the operation range of a single operating element into multiple regions, where each region corresponds to a different command group. This allows the system to handle multiple commands through one element rather than requiring multiple separate switches, thereby maintaining versatility while reducing operational complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension by utilizing the continuous operation range of the operating element (e.g., rotation angle or pressing depth) rather than discrete switch positions. By mapping different operation amounts to different command groups, the system expands the command space without adding more physical components, simplifying the interface while maintaining adaptability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a single operating element with variable operation amount is used, then operation is simplified, but the number of selectable commands is limited

Engineering Contradiction:
Improveoperation simplicityVSAvoidcommand selection range
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent makes the system dynamic by allowing the function of the operating element to change based on the selected command group. When the operation amount falls within a specific range, the system switches to a different command group, enabling the same physical element to access a wide variety of commands through dynamic reconfiguration rather than static assignment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter (operation amount) to control which command group is active. By monitoring whether the operation amount is within a prescribed range, the system switches between different command sets, effectively expanding the command selection range while maintaining simple operation through a single element.

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided is an input device capable of facilitating an operation for inputting, a command such as characters. The input device includes an operation unit of which an operation amount is variable and a control unit. The control unit selects one command group among a plurality of command groups and decides on a command on the basis of the command group selected and the operation amount of the operation unit. The control unit switches the command group selected when the operation amount of the operation unit is in a prescribed range.
