Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If whole-body photon therapy devices are designed to provide therapeutic irradiance levels across the body, then treatment effectiveness is improved, but device weight and size increase making it non-portable
Solution Approach 1:
The device is divided into a main chassis containing electronic components and power supply, a removable therapy head containing LED arrays, and foldable support legs. This segmentation allows the heavy components to be separated from the therapy delivery portion, enabling portability while maintaining therapeutic irradiance levels when assembled.
Solution Approach 2:
The therapy head with LED arrays can be nested within or attached to the main chassis, and the foldable legs can be collapsed into the chassis structure. This nesting approach minimizes the device footprint and weight during transport while maintaining full functionality when deployed.
2Area of stationary object
If photon therapy devices are designed to cover the entire body surface area, then treatment coverage is improved, but device volume and complexity increase
Solution Approach 1:
The device incorporates foldable legs that can be adjusted to different positions and angles, allowing the same device structure to accommodate different body sizes and positions. The collapsible design transforms a potentially complex fixed structure into a dynamic, adaptable one that maintains simplicity.
Solution Approach 2:
The main chassis serves multiple functions: it houses the power supply, controls the LED arrays, provides structural support when legs are attached, and can store or protect the therapy head when not in use. This multi-functionality reduces overall device complexity by eliminating the need for separate components.
3Productivity
If photon therapy devices use high-power LED arrays to deliver therapeutic doses quickly, then treatment speed is improved, but heat generation and power requirements increase
Solution Approach 1:
The patent introduces thermal management components as intermediaries between the high-power LED arrays and the surrounding environment. Heat sinks, thermal pads, and cooling channels act as mediators to efficiently transfer and dissipate heat, allowing high-power LEDs to operate at therapeutic irradiance levels without excessive temperature rise.
Solution Approach 2:
The device replaces traditional mechanical cooling systems (fans, pumps) with passive thermal management solutions integrated into the chassis design. Thermal conduction paths and heat dissipation structures are built into the housing, eliminating moving parts while maintaining effective heat removal from high-power LED arrays.

AI summary
A portable photon therapy system is disclosed herein comprising a chassis, legs, headrest and footrest. When not in use, the legs can be folded, and the headrest and footrest detached and stored inside the chassis, which can be contained within a travel case. The device with case will comply with airline checked baggage requirements for size and weight. The chassis houses arrays of light-emitting diodes (LEDs) on printed circuit boards (PCBs) beneath an acrylic surface (device bed), which emit a plurality of light wavelengths at therapeutic irradiance levels. After device setup and upon selection of the desired light wavelengths (e.g. red or infrared or both) and mode (pulsed or continuous wave) via the control panel, one lays down on the device bed to undergo photon therapy. The present invention comprises a foldable 2-piece chassis for consumer photon therapy, and a single-piece chassis for patient photon therapy by medical professionals.
