Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat therapy devices using lamp modules face issues with reduced durability due to internal air expansion and ambient moisture penetration, leading to malfunctions.
Innovation Solution
A lamp module design featuring a cover glass with a communication portion that allows internal air expansion and includes a sloped opening and closing portion with a slit to discharge heated air externally, coupled with a bracket system for electrode terminals and a cap member for sliding movement, along with a cleaning part for maintaining the cover glass's cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a lamp module is used for heat therapy, then heating function is provided, but internal air expansion applies external force to the cover glass reducing durability
Solution Approach 1:
The patent introduces a communication portion that segments the sealed space into internal and external portions, allowing controlled air exchange. This prevents complete sealing while maintaining structural integrity, resolving the contradiction between heat therapy function and cover glass durability by accommodating thermal expansion without compromising the overall structure.
Solution Approach 2:
The communication portion is designed with a movable opening and closing portion that dynamically adjusts to internal air pressure changes. When internal air expands due to heating, the opening and closing portion moves to open the communication channel, releasing excess pressure. This dynamic adjustment prevents excessive external force on the cover glass while maintaining the heating function.
2Reliability
If the lamp module is sealed, then moisture-proof performance is improved, but ambient moisture penetration causes malfunctions
Solution Approach 1:
The communication portion is strategically positioned and designed with specific local characteristics - it remains closed during normal operation to maintain moisture-proof performance, but opens locally when internal air pressure increases. This localized quality change allows the system to maintain overall sealing while providing a controlled release mechanism, preventing moisture ingress while accommodating thermal expansion.
Solution Approach 2:
The opening and closing portion acts as an intermediary element between the internal sealed space and the external environment. It mediates the conflict between maintaining sealing (for moisture-proof performance) and allowing pressure release (to prevent moisture penetration). The intermediary opens only when necessary, controlled by internal air pressure, thus maintaining reliability while preventing harmful moisture ingress.
3Strength
If the cover glass is completely sealed, then durability is improved, but internal air expansion creates harmful external force
Solution Approach 1:
The communication portion segments the internal space from the external environment while maintaining overall structural integrity. This segmentation allows the cover glass to remain durable and sealed for most of its surface area, while the segmented communication channel provides a controlled pathway for pressure equalization, preventing harmful external forces.
Solution Approach 2:
The system transitions from a static completely sealed structure to a dynamic structure with a movable opening and closing portion. This dynamic element allows the system to maintain durability through near-complete sealing while automatically adjusting to release internal pressure when necessary, preventing harmful external forces on the cover glass.
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 design enhances the durability and moisture-proof performance of the lamp module by reducing external forces on the cover glass and preventing moisture ingress, thereby improving the overall reliability and longevity of the heat therapy device.
Implementation Method 1
internal air expands due to an increase in an internal temperature of a lamp module
Implementation Method 2
internal air expands due to an increase in an internal temperature of a lamp module to repeatedly apply an external force to a cover glass
Implementation Method 3
The opening and closing portion may be sloped such that an internal sectional area decreases toward one side of the first bracket from a lower portion of the side wall portion
