Single-Operator Input with Split LED State Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices cannot easily output multiple control commands using a single operator and provide clear visual indicators for state changes.
Innovation Solution
An input device with a single operator that receives different operation types (short-time and long-time push) and outputs corresponding commands, accompanied by distinct LED displays for each state, allowing users to confirm the state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single operator is used for input operations, then the device structure is simplified and ease of operation is improved, but the ability to output multiple control commands is limited
Solution Approach 1:
The operator detects different operation types by recognizing parameters such as operation duration (short-time vs. long-time push) or operation pattern (single push vs. continuous push). This allows a single operator to generate multiple distinct control commands based on the detected operation parameters, resolving the contradiction between simplicity and versatility.
2Loss of information
If multiple display regions are used to indicate different states, then state indication clarity is improved, but the device complexity increases
Solution Approach 1:
A single display device is designed to perform multiple functions by displaying different visual information in different regions or modes. The display device can show various state indications (first state, second state, etc.) using the same physical display element, thereby achieving clear state indication without increasing device complexity through multiple separate display components.

AI summary
An input device includes an operator, an output unit, and a display device. The output unit is configured to receive a first operation and a second operation. The output unit is configured to output a first command corresponding to the first operation and a second command corresponding to the second operation. The display device is configured to perform a first display corresponding to a first state in which the first command is output and a second display corresponding to a second state in which the second command is output. The display device is disposed in a periphery of the operator. The display device is divided into a first display region and a second display region. The first display includes a state in which the first display region is displayed, and the second display includes a state in which the second display region is displayed.
