Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with optical modules lack independent operation of light-emitting and light-receiving elements, leading to inefficiencies in various photographing environments.
Innovation Solution
Incorporating a substrate with both light-emitting and light-receiving elements, where the light-emitting elements operate independently from the light-receiving elements, allowing for simultaneous and independent control of their states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If light-emitting elements and light-receiving elements are integrated on the same substrate, then the device complexity is reduced and space is saved, but the operational independence between the two elements is compromised
Solution Approach 1:
The optical module is segmented into distinct light-emitting element regions and light-receiving element regions on the same substrate. Each region can be independently controlled through separate control circuitry, allowing the light-emitting elements and light-receiving elements to operate independently while maintaining integrated packaging.
2Adaptability or versatility
If light-emitting elements and light-receiving elements operate independently, then the functionality and flexibility are enhanced, but the device complexity increases due to separate control circuitry
Solution Approach 1:
The substrate serves multiple functions: it provides mechanical support for both light-emitting and light-receiving elements, enables electrical connection through separate control circuitry, and facilitates optical interaction between the elements. This multi-functionality reduces the need for additional separate structures.
3Ease of manufacture
If both light-emitting and light-receiving elements are disposed on the same substrate, then the manufacturing process is simplified, but the operational independence and control precision are reduced
Solution Approach 1:
Different regions of the substrate are designed with specific local qualities: the light-emitting element region has properties optimized for light emission (e.g., electrode patterns, doping concentrations), while the light-receiving element region has properties optimized for light detection. This allows both elements to be manufactured on the same substrate with high precision for their respective functions.
