Remote Control Device Distance Verification Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems fail to allow remote control of electronic devices from a distance and often result in erroneous device selection due to distance limitations and multiple devices of the same kind being available for control.
Innovation Solution
A remote control device and system that includes an operation instruction inputting part, a control instruction transmitting part, a same kind device determining part, a distance determining part, and a confirmation information notifying part to ensure accurate selection and control of electronic devices by verifying the presence and proximity of devices before transmitting control instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distance threshold limitation is applied to prevent erroneous control, then reliability is improved, but ease of operation deteriorates as users cannot remotely control devices from distant locations
Solution Approach 1:
The system displays feedback information showing the relationship between the selected device and other devices of the same kind, allowing users to verify they have selected the correct device before execution. This feedback mechanism enables accurate remote control selection even when multiple devices exist, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The system introduces an intermediary verification step that displays device relationship information between the selected device and other devices. This intermediary information acts as a mediator that helps users confirm correct device selection without requiring physical proximity, thus maintaining both reliability and ease of operation.
2Adaptability or versatility
If multiple devices of the same kind are allowed to be registered, then adaptability is improved, but reliability deteriorates due to erroneous device selection
Solution Approach 1:
The system provides feedback information that displays the relationship between the selected device and other devices of the same kind. This feedback allows users to verify device selection accuracy even when multiple devices are registered, thus maintaining both adaptability and reliability.
Solution Approach 2:
The system uses visual display differentiation to show the relationship between selected device and other devices of the same kind. By presenting device relationship information in a distinguishable visual format, users can easily identify the correct device among multiple registered devices, maintaining reliability while allowing multiple device registration.
3Reliability
If confirmation display is provided before control transmission, then reliability is improved, but loss of time increases due to additional verification steps
Solution Approach 1:
The system displays only the necessary relationship information between the selected device and other devices of the same kind, providing partial confirmation that is sufficient for user verification without excessive detail. This partial action approach maintains reliability while minimizing time loss.

AI summary
In a remote control device, a confirmation information notifying part notifies confirmation information for transmission of a control instruction before the transmission of the control instruction by a control instruction transmitting part, in a case where when an operation instruction to a selected electronic device is input by an operation instruction inputting part, a same kind device determining part determines that a plurality of the electronic devices of the same kind as the selected electronic device exist, and the distance determining part determines that the distance between the selected electronic device and the remote control device is equal to or larger than the distance threshold value.
