Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray devices face challenges in securely and efficiently establishing electrical connections between the X-ray detector and power terminals, particularly when the device is being inserted into an X-ray table, which can lead to malfunctions and user safety issues due to exposed power contacts.
Innovation Solution
The X-ray device incorporates a power contactor that protrudes from the detector due to a push pin pressure, forming a secure electrical connection with the power terminal through a tapered portion and guide mechanisms, preventing forward or backward movement and ensuring stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power contactor is exposed outside the detector for easy electrical connection, then electrical connection is improved, but user safety deteriorates due to risk of shock from leakage currents
Solution Approach 1:
The power contactor is nested inside the detector housing during transport and storage, then protrudes outward only when needed for electrical connection. This nesting approach allows the contactor to be protected from user exposure during non-operational states while still enabling easy electrical connection during operational states, thus resolving the contradiction between ease of operation and user safety.
Solution Approach 2:
The detector is pre-equipped with a protrusion structure that automatically exposes the power contactor when inserted into the X-ray table. This preliminary preparation eliminates the need for users to manually expose the contactor, ensuring safety by default while maintaining ease of connection through automatic engagement.
2Reliability
If the power contactor protrudes from the detector for electrical connection, then electrical connection reliability is improved, but device complexity increases due to additional protrusion mechanisms
Solution Approach 1:
The protrusion mechanism is merged with the detector housing structure itself, rather than being a separate independent mechanism. The housing is designed with an integrated protrusion that naturally exposes the power contactor during insertion, combining the protective housing function with the protrusion mechanism to reduce overall device complexity while maintaining connection reliability.
Solution Approach 2:
The detector automatically performs the protrusion action through its own insertion motion into the X-ray table, without requiring external actuators or complex control systems. The insertion force itself drives the power contactor outward, making the system self-servicing and reducing mechanical complexity while ensuring reliable electrical connection.
3Object-affected harmful factors
If the power contactor is retracted inside the detector during transport, then user safety is improved, but ease of operation deteriorates due to additional insertion steps
Solution Approach 1:
The detector is pre-configured with the power contactor in a retracted position during transport, and the insertion process itself is designed to automatically trigger the protrusion. Users only need to perform the simple action of inserting the detector, and the system automatically completes the electrical connection sequence, maintaining safety without adding operational complexity.
Solution Approach 2:
The detector automatically manages the power contactor's position based on its insertion state. During transport, the contactor remains retracted for safety; during insertion, the detector self-activates the protrusion mechanism through its own motion, eliminating the need for separate user actions and maintaining ease of operation while ensuring safety.

AI summary
An X-ray device is disclosed. In one embodiment, the device includes an X-ray detector and a power contactor which includes a contact terminal. The device may further include an X-ray table that provides a space into which the X-ray detector is inserted and that includes a push pin pressing the power contactor, wherein the power contactor selectively protrudes from the inside to the outside of the X-ray detector due to a pressure applied by the push pin, and the contact terminal is electrically connected to a power terminal of the X-ray table. The X-ray detector prevents exposure of the power contactor to the outside thereof when the X-ray detector is carried or transported and thus prevents a malfunction of the X-ray detector.
