Solution Overview
Problem
Optical communication modules in portable electronic devices are limited by fixed angles of signal transmission and reception, occupying additional space and compromising communication quality and component arrangement.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical communication module is fixed at a specific angle, then the device structure is simple, but the communication range and quality are limited
Solution Approach 1:
The patent merges the optical communication module with the rotatable component (such as a camera module) into a single integrated unit. This combination allows the optical communication module to inherit the rotatable component's rotational capability, enabling it to change transmission and reception angles without requiring a separate rotating mechanism. The merging resolves the contradiction by achieving angle adaptability through integration rather than adding independent complexity.
Solution Approach 2:
The rotatable component is designed to serve multiple functions: both optical communication (through the integrated light emitter and light receiver) and other functions (such as photography or sensing). By making the component universal, the patent enables the optical communication module to share the rotational mechanism with other functions, thereby improving communication angle range without proportionally increasing device complexity.
2Volume of moving object
If the optical communication module is additionally installed on the periphery of the device, then the module is easily accessible, but it occupies additional space and affects component arrangement
Solution Approach 1:
The patent integrates the optical communication module into the rotatable component's internal structure rather than installing it as an additional peripheral element. This merging eliminates the need for extra peripheral space, allowing the module to share the volume already allocated for the rotatable component. The integration resolves the space occupancy issue while maintaining accessibility through the component's rotational capability.
Solution Approach 2:
The optical communication module is nested within the rotatable component's housing or cavity. The light emitter and light receiver are positioned inside the rotatable component, utilizing its internal volume. This nesting approach allows the optical communication functionality to be embedded within existing structure, significantly reducing overall space requirements compared to peripheral installation.
