Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a fixed built-in light plate is used, then the device structure is simple, but the light coverage angle is limited and cannot illuminate the entire shooting range
Solution Approach 1:
The single fixed light plate is divided into multiple separate light-emitting components (first light-emitting component and second light-emitting component) with different optical axis directions. This segmentation allows each component to cover specific angular ranges, collectively achieving full 360-degree coverage while keeping individual components relatively simple in structure.
Solution Approach 2:
The light-emitting components are made rotatable relative to the base, transforming the fixed illumination system into a dynamic one. The camera lens module and light-emitting components can rotate together to change shooting positions, enabling the illumination angle to adapt to different viewing directions and cover the entire shooting range without requiring complex independent adjustment mechanisms for each light source.
2Illumination intensity
If a fixed light plate is used, then the manufacturing cost is low, but dark areas appear around the edges of the video due to insufficient light projection
Solution Approach 1:
Different light-emitting components are positioned and oriented to provide targeted illumination for different spatial zones. The first light-emitting component with optical axis along the first direction illuminates one set of edges, while the second light-emitting component with optical axis along the second direction (perpendicular to the first) illuminates the opposite edges, ensuring uniform lighting across the entire field of view without creating dark areas.
Solution Approach 2:
The illumination system transitions from a single-direction light source to a multi-dimensional arrangement. By positioning light-emitting components along different axes (first direction and second direction perpendicular to the first) and making them rotatable, the system achieves three-dimensional spatial coverage, eliminating edge dark areas that would occur with a single fixed light plate.
3Adaptability or versatility
If the light plate is fixed inside the machine, then the structure is stable, but the light plate cannot be rotated or tilted to adjust to different viewing angles
Solution Approach 1:
The light-emitting components are mounted on the base in a rotatable manner, allowing them to change orientation dynamically. When the camera lens module rotates to different shooting positions, the light-emitting components rotate together, maintaining stable relative positioning while adapting to various viewing angles. This dynamic design enables the system to cover the entire shooting range without compromising the stability of the overall structure.
4Length of stationary object
If a single light-emitting component is used, then the device is simple, but the effective light projection length is insufficient at certain viewing angles
Solution Approach 1:
The illumination function is segmented into multiple light-emitting components positioned at different locations and orientations. The first light-emitting component projects light along the first direction while the second light-emitting component projects light along the second direction (perpendicular to the first). This segmentation ensures that at any viewing angle, at least one light-emitting component is optimally positioned to provide sufficient light projection length, eliminating the insufficiency that would occur with a single component.
