Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting devices for phototherapy often suffer from reduced breathability and skin irritation due to their design, which can impede the natural breathing and sweating processes when in contact with the skin.
Innovation Solution
A light-emitting device featuring a flexible pad with a three-dimensional structure comprising protrusions and recesses that allow for ventilation and air flow, along with apertures for light-emitting elements, ensuring a skin-friendly interface that maintains breathability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flexible pad uses a flat surface design, then the device can maintain structural simplicity and ease of manufacture, but the breathability of the skin is reduced and skin irritation occurs
Solution Approach 1:
The flexible pad incorporates a three-dimensional structure with numerous protrusions and recesses, creating a porous surface topology. This porous design allows air and sweat to pass through, maintaining skin breathability while preserving the integrity and simplicity of the flexible pad structure.
Solution Approach 2:
The invention transitions from a two-dimensional flat surface to a three-dimensional structure with protrusions and recesses. This dimensional change creates ventilation channels and air pockets that enable skin breathability without compromising the overall structural simplicity or manufacturing complexity of the flexible pad.
2Ease of operation
If the flexible pad conforms closely to the skin surface, then the ergonomic fit and light delivery efficiency are improved, but the natural breathing and sweating processes are impeded
Solution Approach 1:
The flexible pad employs a porous three-dimensional structure with protrusions and recesses that create ventilation channels. This porous design allows the pad to conform closely to the skin for ergonomic fit and efficient light delivery, while simultaneously permitting air circulation and sweat evaporation to maintain natural skin breathing processes.
Solution Approach 2:
The surface of the flexible pad is segmented into numerous protrusions and recesses, creating a micro-structured topology. This segmentation maintains close skin contact for ergonomic fit while the interspersed recesses create air pockets and ventilation channels that preserve skin breathability and sweating functions.
3Ease of manufacture
If the flexible pad uses a flat contact surface, then the manufacturing process is simpler, but skin irritation occurs due to reduced breathability
Solution Approach 1:
The flexible pad incorporates a porous three-dimensional structure with protrusions and recesses that can be integrated into the manufacturing process. This porous design prevents skin irritation by maintaining breathability and reducing moisture buildup, while the manufacturing process remains relatively simple through techniques like molding or embossing the three-dimensional pattern into the flexible material.
