Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional single lens configuration is used, then device complexity is low, but image clarity and energy efficiency cannot be simultaneously optimized
Solution Approach 1:
The patent divides the imaging function into two separate lens sets: a first lens set for optical imaging and a second lens set for energy imaging. This segmentation allows each lens set to be optimized for its specific function, achieving both clear images and energy efficiency without compromising the other.
Solution Approach 2:
The dual lens set configuration enables the projecting system to perform multiple functions simultaneously - optical imaging for picture quality and energy imaging for light source positioning and efficiency. This multi-functionality resolves the contradiction by making the system capable of achieving both image clarity and energy optimization.
2Illumination intensity
If lens aperture is increased to improve image brightness, then illumination intensity improves, but space volume required increases
Solution Approach 1:
The patent introduces a new dimensional approach by adding a second lens set that operates independently in the optical path. This allows the system to achieve high illumination intensity through the first lens set while the second lens set manages energy distribution, effectively decoupling brightness requirements from space volume constraints.
3Volume of moving object
If lens-apex distance is reduced to compact the system, then volume decreases, but optical imaging quality deteriorates
Solution Approach 1:
By segmenting the imaging function into two separate lens sets with different focal lengths, the patent allows the first lens set to maintain optimal optical imaging quality while the second lens set handles energy imaging. This segmentation enables compact overall system volume while preserving optical quality through specialized optimization of each lens set.

AI summary
The invention discloses a projecting system. The projecting system includes two sets of lens. The first set of lens has a first focal length for focusing an incident ray of light to form a first image. The second set of lens has a second focal length for projecting the first image to form a second image. The two sets of lens are separated by a lens-apex distance relative to the light path between the two sets of lens. The second focal length is smaller than or equal to the lens-apex distance. A difference between the second focal length and the lens-apex distance is smaller than or equal to a half of the first focal length.
