Instruction Device Space Detection for Target Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control devices cannot operate target devices in spaces without ultrasonic detection means, limiting their functionality to specific rooms where detection means are arranged.
Innovation Solution
An instruction device with a detection unit, storage unit, and output unit that detects its own space, specifies associated target devices using stored association information, and outputs instruction signals accordingly, allowing operation of target devices across multiple spaces.

Engineering Contradiction Analysis
1Ease of operation
If ultrasonic detection means are arranged in each space to enable automatic target device specification, then the convenience of operation is improved, but the device complexity and cost increase due to requiring multiple detection means deployed throughout the environment
Solution Approach 1:
The instruction device detects its own position using its built-in detection unit without requiring external detection means to be arranged in each space. The device serves itself by utilizing its own detection capabilities to automatically identify the space and specify the target device, eliminating the need for complex external detection infrastructure.
Solution Approach 2:
The detection unit integrated into the instruction device serves multiple functions: it detects the space where the instruction device exists, enables automatic target device specification, and eliminates the need for separate external detection means. This multi-functionality reduces overall system complexity while maintaining ease of operation.
2Device complexity
If the instruction device uses its own detection unit to identify space and target device, then the device complexity is reduced by eliminating external detection means, but the measurement precision of space detection may be compromised
Solution Approach 1:
The instruction device uses its own integrated detection unit to detect its position and identify the space, eliminating the need for external detection means. This self-service approach reduces system complexity while providing sufficient precision for automatic target device specification in practical applications.

AI summary
An instruction device includes: a detection unit that detects a space in which the instruction device exists; a storage unit that stores association information including information indicating that the space and a target device are associated with each other; a specifying unit that specifies the target device associated with the detected space by referring to the association information; and an output unit that outputs an instruction signal corresponding to the specified target device in accordance with an operation by an operator.
