Test System Light-Receiving Unit Segmentation for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test systems face difficulties in easily replacing light-receiving units, as they are often integrated with optical transmission cables or fibers, making it hard to swap or adjust them according to the type of test object or when units fail.
Innovation Solution
A test system design that separates the light-receiving unit from the optical path forming unit, allowing for easy detachment and replacement, with a holding unit and optical path forming unit arranged to efficiently gather light emitted from the test object, and incorporating features like space adjustment and a mirror to optimize light path alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light-receiving unit is integrated with the optical transmission cable or optical fiber, then the system structure is simplified, but the ease of replacing the light-receiving unit deteriorates
Solution Approach 1:
The patent divides the system into separate functional modules: the light-receiving unit (lens) and the optical transmission path (optical fiber/cable). The light-receiving unit is mounted on a holding unit that can be detached from the optical path forming unit, allowing the light-receiving unit to be replaced independently without replacing the entire optical system. This segmentation resolves the contradiction by maintaining structural simplicity while enabling easy replacement.
2Volume of moving object
If the light-receiving unit is integrated with the optical path forming unit, then the system is more compact, but the adaptability to different test objects and failure replacement deteriorates
Solution Approach 1:
The holding unit serves as an intermediate carrier that maintains a compact arrangement while enabling the light-receiving unit to be detached and replaced. The holding unit can be quickly exchanged on the optical path forming unit, allowing different light-receiving units to be used for different test objects without redesigning the entire system. This resolves the contradiction between compactness and adaptability.
Solution Approach 2:
The holding unit and optical path forming unit are designed with universal interfaces that allow different types of light-receiving units to be mounted and exchanged. The optical path forming unit can accommodate multiple holding units, enabling the system to test different types of test objects by simply changing the light-receiving unit, thus achieving multi-functionality and adaptability.
3Ease of manufacture
If the light-receiving unit is integrated with the optical transmission cable, then the assembly is simpler, but the ease of repair deteriorates
Solution Approach 1:
The patent segments the light-receiving unit from the optical transmission cable by introducing the holding unit as an intermediate carrier. The light-receiving unit is mounted on the holding unit, which can be detached from the optical path forming unit. This segmentation allows the light-receiving unit to be replaced independently for repair purposes without disturbing the optical transmission cable or other system components, thus improving ease of repair while maintaining assembly simplicity through modular design.
Solution Approach 2:
The light-receiving unit is extracted as a separable component from the integrated system. By mounting it on a detachable holding unit, the light-receiving unit can be easily removed and replaced when failed, without needing to disassemble the entire system or handle the optical transmission cable. This extraction approach significantly improves ease of repair while keeping the overall assembly process simple through standardized interfaces.
Applied Scientific Principles

Function Achieved in This Case
Enables straightforward replacement of light-receiving units, improving test system flexibility and efficiency by allowing for easy attachment and detachment, and ensuring reliable light gathering near the focus point.
Implementation Method 1
an optical transmission path as a path of light received by the light-receiving unit (17)
Implementation Method 2
the light-receiving unit (17) is a lens to which light emitted from the test object (4) converges
Implementation Method 3
the optical path forming unit (15) has a mirror at a position where light emitted from the test object (4) is converged by the lens (17c), and the mirror changes an advancing direction of light

AI summary
A test system is characterized by a holding unit that holds a light-receiving unit receiving light emitted from a test object and an optical path forming unit that is formed with an optical transmission path as a path of the light received by the light-receiving unit, in which the optical transmission path is formed of a different member from the light-receiving unit. Since the test system has such a configuration, replacement of the light-receiving unit that receives the light emitted from the test object can be facilitated.
