Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional supplemental lighting is used, then lighting is provided, but shadows are cast and illumination is uneven
Solution Approach 1:
The lighting device is divided into multiple independent LED modules arranged in a circular pattern around the core body, with each module containing multiple LEDs positioned at different heights and angles. This segmentation allows each module to illuminate different portions of the target area, eliminating shadows and ensuring uniform illumination across the entire field of view.
Solution Approach 2:
The lighting device transitions from conventional single-point or linear lighting to a three-dimensional circular arrangement of LED modules around the core body. This multi-dimensional configuration enables 360-degree illumination coverage, casting light from multiple directions simultaneously to eliminate shadows and improve illumination uniformity.
2Manufacturing precision
If conventional lighting is used, then area illumination is provided, but details are not fully captured
Solution Approach 1:
Each LED module is positioned and oriented to provide localized illumination to specific portions of the target area. The modular design with multiple LEDs per module allows precise control over light distribution patterns, ensuring that every detail within the field of view receives appropriate illumination intensity and angle for high-quality capture.
3Illumination intensity
If supplemental lighting is added, then illumination is improved, but the lighting equipment becomes more complex
Solution Approach 1:
Multiple LED modules are merged into a single integrated lighting device that attaches to the camera or scanning equipment. The modular LED components are combined within a unified housing structure that includes mounting mechanisms, power supply, and control circuitry, simplifying the overall system while maintaining high illumination quality.
4Adaptability or versatility
If existing lighting technologies are used, then basic illumination is provided, but 360-degree capture is compromised
Solution Approach 1:
The lighting device is designed with universal compatibility for various camera types and scanning equipment. The circular arrangement of LED modules provides omnidirectional illumination that works with 360-degree cameras, LiDAR systems, and other imaging devices, making the lighting solution adaptable to multiple applications and platforms.

AI summary
A lighting device is disclosed. The lighting device includes a core body that is shaped such that a light emitting diode sheet may be wrapped around the surface of the core body. A groove of a bottom housing of the lighting device is secured to a bottom portion of the core body and a groove of a top housing is secured to a top portion of the core body. The lighting device includes a hollow cavity extending from the bottom housing into the core body. The hollow cavity may be positioned over a portion of a tripod or mount, and a clamp is utilized to secure the lighting device to the tripod or mount. The lighting device may be activated, thereby causing a plurality of light emitting diodes of the light emitting diode sheet to emit light 360 degrees outwards from the core body of the lighting device.
