Wireless X-Ray Controller with Mount Detection and Loss Alerts

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless remote controllers for devices, including X-ray imaging devices, often get lost or left behind due to lack of notifications for battery depletion or device abnormalities, and no existing solutions provide alerts for this issue.

Innovation Solution

An operation device with a control unit that wirelessly operates a main unit and is held in a removable manner, providing notifications via a notification unit when removed for a predetermined time, using a detection unit to sense mounting status and disable operations to prevent loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless operation device is used, then ease of operation is improved, but reliability deteriorates due to loss or misplacement

Engineering Contradiction:

Improvewireless operationVSAvoiddevice loss prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements feedback by detecting whether the operation device is mounted on the holder and providing notifications based on this state. The detection unit monitors the mounting status and triggers notifications when the device is unmounted for extended periods, creating a closed-loop feedback system that addresses the reliability issue while maintaining wireless operation benefits

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary action by providing advance notifications before the device is actually lost or misused. The notification is triggered after a predetermined time period of unmounted state, allowing the user to retrieve the device before it causes problems, thus preventing loss in advance

Inventive Principle:

Principle #10Preliminary action

2Reliability

If notification functionality is added, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improvedevice loss preventionVSAvoidnotification system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The notification unit serves multiple functions: it notifies users about device unmounting status, alerts about potential loss, and can provide guidance for retrieval. This multi-functionality justifies the added complexity by consolidating multiple notification purposes into a single integrated system rather than requiring separate mechanisms for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An operation device (200) for wirelessly operating an X-ray imaging device (1) is held in a removable manner in a holder (100) included in the X-ray imaging device (1). The operation device (200) includes a control unit (211) that provides a notification when detecting that a predetermined condition is satisfied while the operation device (200) remains removed from the holder (100). This structure provides various notifications including a notification for preventing the operation device from being left or lost.
