Optical Sensor Sleeve for Light Guidance and Interference Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with optical sensors face challenges in effectively guiding and isolating light to prevent interference between optical components, leading to inefficient light utilization and potential cross-talk between sensors and emitters.
Innovation Solution
The electronic device incorporates a sleeve with an optical element and glue beads to create a controlled light path to the sensor, while using a cap with partitions to isolate the light emitter from the sensor, ensuring that light reaches the sensor only through the sleeve and preventing direct illumination from the emitter.

1Use of energy by moving object
If a sleeve with traversing passage is mounted on the chip to guide light to the optical component, then light guidance efficiency is improved, but light interference and cross-talk between optical components may occur
Solution Approach 1:
The device is segmented into distinct functional zones using the sleeve structure with its traversing passage. The sleeve creates separate light paths for different optical components, allowing light to be guided efficiently to the intended optical component while preventing cross-talk and interference between adjacent components on the chip.
Solution Approach 2:
The sleeve provides localized light guidance properties through its traversing passage, creating a controlled optical environment at specific locations on the chip. This local optimization ensures that light reaches the intended optical component with high efficiency while maintaining isolation from other optical components, thus preventing interference.
2Area of stationary object
If optical components are placed close together on the chip to reduce device size, then device compactness is improved, but light isolation between components becomes difficult
Solution Approach 1:
The sleeve structure segments the optical path into distinct traversing passages that can accommodate multiple optical components in close proximity. Each passage acts as an independent light guide, enabling compact arrangement of components while maintaining optical isolation through the segmented light paths within the sleeve.
Solution Approach 2:
Multiple optical components are nested within the same chip area, with the sleeve providing a containing structure that houses multiple traversing passages. This nesting arrangement allows compact integration of components while the sleeve's internal structure maintains light isolation between the nested components.
