Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple light sources with different wavelengths are used to illuminate surrounding objects, then object identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the illumination function into multiple light sources emitting at different wavelengths, with each wavelength component selectively reflected by corresponding optical elements to different image sensor regions. This segmentation enables spectral discrimination for improved object identification while maintaining manageable system complexity through functional decomposition.
Solution Approach 2:
The patent extends the imaging capability from spatial dimensions to spectral dimensions by incorporating multiple wavelengths. The optical element separates light by wavelength and directs different spectral components to different image sensor areas, adding a spectral dimension to the identification process without requiring complete system redesign.
2Adaptability or versatility
If an optical element with wavelength-selective reflection is introduced, then multi-wavelength light guidance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes optical elements with specific reflective parameters tuned to particular wavelengths. By changing the optical parameters (reflective wavelengths) of the elements, the system achieves multi-wavelength guidance capability. These parameterized optical components can be manufactured using standard techniques with controlled spectral properties.
Solution Approach 2:
The optical element acts as an intermediary between the multiple light sources and the image sensor. It mediates the interaction by selectively reflecting specific wavelengths to designated sensor regions, simplifying the overall system architecture compared to direct multi-wavelength imaging approaches.
3Adaptability or versatility
If sequential activation of light sources is implemented, then light guidance to multiple objects is improved, but time consumption increases
Solution Approach 1:
The patent employs sequential or periodic activation of light sources at different wavelengths, with each source activated in turn to illuminate specific objects. The image sensor captures reflected light from each wavelength during its active period. This periodic action enables multi-object illumination and identification while managing temporal resources efficiently.

AI summary
The disclosure is related to a sensor module, a sensor unit and a system for recognizing surrounding objects and defining an environment. The sensor module is installed in a sensor unit. The sensor module includes an optical element guiding the lights from the objects surrounding the sensor unit and to an image sensor, and the image sensor is used to sense the lights from the objects. The light can be directly from a light source inside the surrounding object or reflected by the object surface. The objects can be identified according to optical features obtained by the image sensor from surfaces of the objects. When the image sensor receives the two lights, guided by the optical element, and reads optical features being regarded as the unique IDs to identify the objects respectively. Therefore, an environment around the sensor unit can be defined.
