Detector Cover Light Guide for Visible Test Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detectors face challenges in identifying test information when partially covered by test jigs during testing, as indicator lights can be obscured, making it difficult for users to verify test results.
Innovation Solution
A disaster prevention apparatus with an outer cover and integrated indicators that protrude from the side portion, allowing light to be refracted, dispersed, or reflected and exposed even when partially covered by test equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a test jig covers at least a part of the detector to perform heat application testing, then the testing function is achieved, but the indicator light becomes hidden and test information becomes invisible
Solution Approach 1:
The indicator is extended from the front surface to the side surface of the detector, changing its spatial dimension. This allows the indicator to be viewed from the side direction even when the front surface is covered by the test jig during heat application testing, resolving the contradiction between maintaining testing function and ensuring information visibility.
2Device complexity
If the indicator is integrated into the outer cover as a thin portion, then the device complexity is reduced, but the light transmission capability must be sufficient
Solution Approach 1:
The outer cover is designed with a thin portion specifically at the indicator location, while other portions maintain their original thickness. This localized thinning provides sufficient light transmission capability for the indicator function without compromising the overall structural integrity and protection function of the outer cover, resolving the contradiction between simplified structure and adequate light transmission.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures that test information is visible and identifiable even when the apparatus is partially covered, reducing the need for additional components and lowering costs.
Implementation Method 1
a spectroscopic portion that refracts, disperses, or reflects light output from a light emitter and that guides the light to the entirety of the thin portion and the entirety of the detection element protector
Implementation Method 2
a spectroscopic portion that refracts, disperses, or reflects light output from a light emitter and that guides the light to the entirety of the thin portion and the entirety of the detection element protector
Implementation Method 3
a spectroscopic portion that refracts, disperses, or reflects light output from a light emitter and that guides the light to the entirety of the thin portion and the entirety of the detection element protector
Implementation Method 4
the thin portion is thin enough to be able to transmit at least some light

AI summary
There is provided a disaster prevention apparatus that allows information about a test to be identified even in a state where at least a part of the disaster prevention apparatus is covered with a test apparatus. A detector 100 includes: an outer cover 11; and an indicator that outputs at least information about a test of a disaster prevention apparatus by emitting light, and that is provided in the outer cover 11. When at least a part of the outer cover 11 is covered with a test apparatus in order to perform the test of the detector 100, at least a part of an indication surface of the indicator is exposed to an outside of the test apparatus. The indicator is formed in a side portion of the outer cover 11, the indicator is formed in an edge portion of a front portion of the outer cover 11, and the indicator is a part of a light guide portion 111 that is formed in the outer cover 11, and that guides light from a light emitter.
