Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical measurement devices with fixedly connected irradiation and main elements are less portable and prone to accidental light irradiation to objects other than the subject due to the lack of a secure detachment mechanism.
Innovation Solution
An optical measurement device featuring a detachable light transmitting element and a light block element that blocks stray light when the transmitting element is detached, ensuring safe operation and improved portability by preventing light from being directed outside during attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the irradiation probe and main element are fixedly connected through the optical connector, then the light transmission stability is improved, but the portability and ease of movement of the main element deteriorates
Solution Approach 1:
The device is divided into separable components: the main element can be moved independently from the irradiation probe. The optical connector allows for detachable connection, enabling the main element to be transported separately while maintaining the ability to connect securely when needed.
2Ease of operation
If the irradiation probe is detached from the main element to improve portability, then the ease of movement is improved, but the risk of erroneous light irradiation to other objects increases
Solution Approach 1:
The light blocking element is positioned in advance to prevent erroneous light irradiation before it can occur. When the optical transmitting element is detached, the light blocking element automatically blocks the light emission aperture, preventing light from reaching unintended targets such as human eyes.
Solution Approach 2:
The light blocking element acts as an intermediary safety mechanism between the light source and the external environment. It intercepts and blocks light that would otherwise escape through the detached optical connector, thereby preventing harmful irradiation to surrounding objects.
3Object-affected harmful factors
If a light blocking element is added to prevent erroneous irradiation, then the safety is improved, but the device complexity increases
Solution Approach 1:
The light blocking element is integrated with the existing optical connector structure. By merging the safety function into the connection mechanism itself, the patent avoids adding a completely separate component, thereby minimizing the increase in device complexity while still achieving effective light blocking.
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
The solution effectively prevents accidental light irradiation to objects other than the subject while enhancing the portability and convenience of the device by ensuring the light block element is in place during both attachment and detachment processes.
Implementation Method 1
an optical transmitting element that comprises an optical fiber and is attachable-and-detachable relative to the light emission aperture and transmits the light to the light emission point arranged to the subject
Implementation Method 2
a light block element that blocks the light irradiated from the light emission aperture to outside under the condition in which the optical transmitting element is detached from the light emission aperture
Data Source
AI summary
An optical measurement device that comprises an apparatus main element including a light emission aperture, a light emission probe element that includes the optical fibers and that transmits light through it, and the other end of the optical fibers being detachably attached relative to the light emission aperture, and a light block element that blocks the light irradiated from the light emission aperture under the condition in which the light emission probe element connected to the apparatus main element is detached from the light emission aperture.
