Detector Grid Handle Auto-Locking for Secure Mobile X-Ray Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grid handles for mobile x-ray devices suffer from inadequate locking mechanisms, leading to potential detector displacement during use, and require disengagement for charging, while the lightweight plastic material used for the handle results in a slippery grip, making handling difficult.
Innovation Solution
A grid handle with an auto-locking mechanism featuring a latch and lock system, biased by springs, ensures secure retention of detectors, and a design that allows charging without removing the detector from the handle, combined with grip enhancements to prevent slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a lightweight plastic material is used for the grid handle, then the handle weight is reduced, but the grip becomes slippery and handling becomes difficult
Solution Approach 1:
The grid handle combines lightweight plastic material with textured grip surfaces or grip-enhancing coatings to maintain low weight while improving grip security. The composite structure integrates the bulk plastic body with surface treatments that provide friction and prevent slippage during handling.
2Device complexity
If a simple locking mechanism is used, then the device complexity is reduced, but the detector may become inadvertently displaced during use
Solution Approach 1:
The locking mechanism is designed to automatically engage and lock when the detector is inserted into the grid handle, eliminating the need for manual locking operations. The self-locking feature ensures reliable detector retention while maintaining simplicity through automatic operation based on the insertion action itself.
Solution Approach 2:
The locking mechanism transitions from a static simple latch to a dynamic system that automatically engages based on the insertion motion. The mechanism uses the act of inserting the detector to trigger the locking action, providing reliable retention without adding complex manual control systems.
3Ease of manufacture
If the grid handle requires disengagement to charge the detector, then the charging process can be simplified, but the time required for charging increases due to repeated engagement and disengagement
Solution Approach 1:
The grid handle design integrates the charging function within the existing encasement structure, allowing the detector to be charged while remaining secured in the handle. This multi-functional design combines retention and charging capabilities, eliminating the need to remove the detector for charging and reducing time loss from repeated engagement and disengagement.

AI summary
A grid handle for a detector utilized with a mobile x-ray device includes an encasement for releasably receiving and retaining the detector therein. The encasement has a body including an interior adapted to receive the detector therein, a handgrip extending along a top edge of the body and an auto-locking mechanism disposed on the body and operable to secure the detector within the interior of the body. The auto-locking mechanism includes a latch moveably mounted to the body, a first biasing member engaged between the latch and the body, a lock moveably mounted to the latch and the body, and a second biasing member engaged between the lock and the body. The auto-locking mechanism does not require addition components for assembly on the encasement, and the encasement can include a grip enhancement structure disposed on the handgrip and a securing tab opposite the auto-locking mechanism to define a connector space.
