Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate optical components (light pipe, prism component, lens component) are used for guiding light, then light guidance functionality is achieved, but optical structure becomes complicated and assembly tolerance increases
Solution Approach 1:
The patent merges the light pipe, prism component, and lens component into a single integrated optical component. This integration maintains the light guidance functionality while eliminating the complexity of assembling multiple separate components, directly resolving the contradiction between functional reliability and structural complexity.
2Reliability
If separate optical components are used, then light guidance is achieved, but manufacturing cost increases
Solution Approach 1:
By combining multiple separate optical components into a single integrated component, the patent reduces the number of parts that need to be manufactured and assembled. This integration simplifies the manufacturing process and reduces overall manufacturing cost while preserving the essential light guidance function.
3Stability of the object's composition
If additional fixing structure is applied for fixing optical components and light source, then component stability is improved, but structure becomes more complicated
Solution Approach 1:
The patent integrates the optical components and light source into a unified structure, eliminating the need for separate fixing structures. This integration maintains component stability through the inherent structural design while avoiding the added complexity of additional fixing mechanisms.
4Reliability
If transparent component is embedded in housing for light transmission, then light transmission functionality is achieved, but assembly tolerance and manufacturing cost increase
Solution Approach 1:
The patent integrates the transparent light transmission component with the housing structure itself, eliminating the need for separate embedded transparent components. This integration maintains light transmission functionality while simplifying assembly and reducing tolerance requirements, as the housing serves dual purposes as both structural enclosure and optical transmission medium.

AI summary
According to the claimed invention, an optical pointing device includes a cover having a transparent part, and a sensing component installed inside the cover. The sensing component includes a light emitting module for emitting light, and a light sensing module for sensing light transmitted from the transparent part. The optical pointing device further includes a light guiding component installed between the sensing component and the cover. The light guiding component includes a reflecting part for reflecting the light emitted from the light emitting module to the transparent part, and a condensing part integrated with the reflecting part monolithically for condensing light transmitted from the transparent part to the light sensing module. The light emitted from the light emitting module is reflected to the transparent part by the reflecting part and then reflected back to the transparent part and the condensing part by a shelter disposed above the cover.
