Solution Overview

Problem

Conventional radiation detecting devices with fixed handle coupling directions face difficulties in rapid and stable attachment, leading to potential device damage during handling due to instability and clearance issues.

Innovation Solution

A handle structure with a shaft rotation latch mechanism that allows detachable coupling in any direction, minimizing clearance and enhancing stability by using first and second latch shafts, connecting shafts, push shafts, and a button for secure latching to the radiation detecting device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handle is slid into a groove on the radiation detecting device, then the handle can be coupled to the device, but the coupling direction is limited to one direction and clearance exists between components

Engineering Contradiction:
Improvecoupling operationVSAvoidcoupling direction
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The latch shafts are designed to rotate around an axis perpendicular to the coupling groove, transforming a linear sliding motion into a rotational latching motion. This dimensional change allows the handle to be coupled from multiple directions while maintaining secure attachment through the rotational locking mechanism.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The coupling mechanism transitions from a static groove-to-handle fit to a dynamic rotational latching system. The latch shafts can rotate to engage with the coupling groove, and the push shafts provide dynamic feedback during the coupling process, enabling adaptive coupling from different orientations.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the handle is slid into a groove on the radiation detecting device, then the handle can be coupled to the device, but clearance exists between components reducing coupling stability

Engineering Contradiction:
Improvecoupling operationVSAvoidcoupling stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The latch shafts act as intermediary elements between the handle and the radiation detecting device. Instead of direct contact between the handle groove and device, the latch shafts mediate the connection by rotating into the coupling groove and locking it, eliminating clearance and enhancing stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The coupling mechanism is divided into separate functional components: the latch shafts for locking, the push shafts for actuation, and the connecting shaft for coordination. This segmentation allows each component to perform its specific function optimally, with the latch shafts providing secure engagement while minimizing clearance.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If a fixed coupling direction is used for the handle, then the structure is simple, but rapid coupling and separation between handle and device cannot be achieved

Engineering Contradiction:
Improvecoupling structureVSAvoidcoupling speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The coupling mechanism is designed to be self-aligning and self-latching. When the handle is brought near the device, the latch shafts automatically rotate into the coupling groove under spring force, and the push shafts automatically engage to lock the connection. This self-service capability enables rapid coupling without complex alignment procedures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The latch shafts are pre-loaded with spring force in a retracted position, ready to rotate into the coupling groove. The push shafts are pre-positioned to apply force to the latch shafts upon contact with the device. This preliminary preparation enables immediate latching upon coupling initiation, significantly increasing coupling speed.

Inventive Principle:
Principle #10Preliminary action

AI summary

A handle structure is detachably coupled to a radiation detecting device. The handle structure includes: a body to be gripped by a user; first and second latch shafts each having one end protruding from the body to be inserted into and coupled to a coupling groove formed on the radiation detecting device; a connecting shaft connecting the other ends of the first and second latch shafts to each other; first and second push shafts brought into contact with the radiation detecting device and vertically moving upwards; a first connecting portion connecting the first push shaft to the first latch shaft; a second connecting portion connecting the second push shaft to the second latch shaft; and a button moved by manipulation of a user to release a coupling state of the first and second latch shafts.
