UV Light Treatment Housing Structure for Thermal Deflection Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The housing of light treatment devices experiences thermal expansion due to heat emitted by the light source, leading to deflection and potential interference with internal members, particularly around the opening for object conveyance.
Innovation Solution
Incorporating a heat deflection reducer, such as a band region with a separate member that allows thermal expansion in one direction while preventing shift in orthogonal directions, or using a cooler or light shield to manage heat distribution and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light source emits ultraviolet light for treatment, then the treatment function is achieved, but heat is generated causing housing deflection
Solution Approach 1:
The housing is divided into multiple regions including a band region surrounding the opening and other regions. The band region is specifically designed with thermal expansion release functionality to handle the heat concentration problem locally, while other regions maintain structural integrity.
Solution Approach 2:
Different regions of the housing are given different thermal properties. The band region is designed to release thermal expansion, while other regions maintain rigid structural support. This local differentiation allows the housing to accommodate heat from the light source without overall deflection.
2Strength
If the housing is made rigid to maintain structure, then structural integrity is improved, but thermal expansion causes deflection around the opening
Solution Approach 1:
The housing structure is segmented into a rigid main body and a flexible band region. The band region surrounding the opening is designed to move independently to accommodate thermal expansion, while the rest of the housing maintains its rigid structural integrity for support.
Solution Approach 2:
The housing has non-uniform thermal properties: the band region is designed with thermal expansion release capability while other regions maintain rigid structural properties. This allows localized adaptation to heat without compromising overall structural strength.
3Use of energy by moving object
If heat is concentrated in a local region, then energy efficiency is improved, but temperature difference causes differential thermal expansion and deflection
Solution Approach 1:
The patent converts the harmful effect of localized heat concentration into a beneficial design feature by creating a band region specifically designed to handle thermal expansion. The heat concentration that would normally cause deflection is now managed by the flexible band region, allowing energy-efficient localized heating without structural damage.
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 heat deflection reducer effectively reduces housing deflection around the opening, preventing interference with internal components and maintaining the integrity of the light treatment process.
Implementation Method 1
a light source that irradiates a treatment object conveyed along a conveyance path with ultraviolet light
Implementation Method 2
The heat deflection of the housing is caused by heat generated by the light source or the like disposed in the housing being transferred to the housing
Implementation Method 3
When the housing is heated, the housing expands
Implementation Method 4
The engagement mechanism may allow the band member to release thermal expansion in an extending direction of the band member with respect to the main body, that is, may restrict shift in a direction orthogonal to the extending direction while allowing elongation of the band member
