Solution Overview

Problem

Conventional X-ray imaging systems face challenges in allowing technicians to effectively interact with and monitor the status of the system and patient due to distance and the limitations of cord-based handswitches, which can interfere with equipment and become damaged.

Innovation Solution

A handheld interface device that communicates wirelessly with the X-ray system, enabling technicians to control exposure, receive operational data, and display patient information, while eliminating the need for a physical cord by using wireless communication protocols like IEEE 802.15.4, UWB, or Bluetooth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cord-based handswitch is used to allow the technician to trigger the X-ray exposure from a distance, then the technician's safety is improved by reducing radiation exposure, but the cord may interfere with or disrupt other equipment within the room and may become damaged over time due to repeated stretching

Engineering Contradiction:
Improvetechnician safetyVSAvoidcord interference and damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent removes the cord from the handswitch system, extracting the harmful element that causes interference with equipment and potential damage. The wireless handswitch eliminates the physical cord while maintaining the ability to trigger X-ray exposure from a distance, thereby preserving technician safety without the associated hazards.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical cord-based connection with a wireless communication system. The handswitch communicates with the X-ray system through wireless signals (such as radio frequency communication), substituting the mechanical cord with an electromagnetic field-based transmission medium, thereby eliminating cord-related interference and damage issues.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the technician is positioned away from the X-ray system behind a shielded barrier, then radiation exposure is reduced, but it becomes difficult for the technician to know the status of and interact with the X-ray system and patient

Engineering Contradiction:
Improveradiation protectionVSAvoidsystem interaction
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent incorporates feedback mechanisms in the wireless handswitch system, including visual indicators (such as LEDs) that provide real-time status information about the X-ray system's operational state. The handswitch displays information such as whether the system is ready for exposure, currently exposing, or in error states, enabling the technician to monitor system status without being physically close to the equipment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The wireless handswitch acts as an intermediary device between the technician and the X-ray system. It transmits control commands wirelessly to trigger exposures and receives status information from the system, mediating the interaction so the technician can control and monitor the system from a safe distance without direct physical contact or proximity to radiation sources.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a cord is extended to allow remote operation of the handswitch, then the technician can operate the system from a greater distance, but the extended cord may interfere with other equipment and become damaged due to repeated stretching

Engineering Contradiction:
Improveoperating distanceVSAvoidcord durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical cord extension with a wireless communication system. The handswitch communicates with the X-ray system through wireless signals, eliminating the need for any physical cord connection. This allows the technician to operate the system from any distance within the wireless signal range without the cord becoming stretched or damaged.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
