Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED therapy beds face issues with ineffective light penetration due to LEDs being spaced too far from the body, distortion of light energy by acrylic covers, and uneven temperature distribution across the body, leading to reduced therapeutic benefits.
Innovation Solution
A LED therapy bed with separately controlled LED modules, thermal sensors, and fans to maintain optimal skin temperature, placed very close to the body, and an acrylic polymer cover that minimizes distortion and ensures uniform energy delivery across the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LEDs are spaced several inches from the user in a retrofitted tanning bed design, then the device structure is simpler and easier to manufacture, but light penetration effectiveness is reduced and therapeutic energy delivery is insufficient
Solution Approach 1:
The therapy bed is divided into separate modular sections (head section, torso section, leg sections) that can be independently adjusted. This allows the LED arrays in each section to be positioned at optimal distances from the user's body, ensuring effective light penetration while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The bed incorporates adjustable positioning mechanisms that allow dynamic adjustment of LED array distances from the user's body. The sections can be raised or lowered to optimize the proximity of LEDs to different body parts, ensuring therapeutic effectiveness while maintaining a simple retrofitted tanning bed structure.
2Strength
If an acrylic cover is used in the LED therapy bed, then the structural integrity and safety are improved, but the preset angle of emitted light is distorted and power output is reduced
Solution Approach 1:
The acrylic cover is designed with locally optimized properties - specific regions have varying thicknesses or refractive index characteristics to minimize light distortion in critical areas while maintaining overall structural integrity. This allows the cover to protect the LED arrays without significantly compromising light output or angle precision.
3Ease of manufacture
If a retrofitted tanning bed design is used, then manufacturing cost is reduced, but simultaneous temperature control of all body parts becomes impractical and uneven heating occurs
Solution Approach 1:
The temperature control system is segmented into independent zones corresponding to different body parts (head, torso, legs). Each zone has its own heating and cooling control, allowing simultaneous and independent temperature regulation of all body parts while maintaining the cost-effective retrofitted tanning bed structure.
Solution Approach 2:
The bed incorporates dynamic temperature control capabilities with independent thermal regulation for each section. Heating and cooling elements can be activated simultaneously in different zones, allowing the system to adapt temperature distribution to match the user's body contours and thermal needs, ensuring uniform therapeutic temperature across all body parts.
4Reliability
If LEDs are positioned at optimal close proximity to the body, then light penetration and therapeutic energy delivery are maximized, but the device complexity and control requirements increase
Solution Approach 1:
The control system is organized into independent modules for each LED array section. Each module can be controlled individually, allowing precise positioning and activation of LEDs at optimal proximity to different body parts without requiring complex centralized control. This modular approach maximizes therapeutic energy delivery while keeping the control system manageable.
