Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted electronic devices are bulky due to multiple functional modules and have limited radar beam coverage and imaging capabilities due to the limited number of antenna elements, making it difficult to integrate both imaging and radar sensors effectively.
Innovation Solution
An image sensing device that integrates multiple lens groups, antenna elements, and image sensing elements into a single module, allowing for increased beam directions and scanning areas by sharing the lens group for both sensing beams and reflected light, and using a position adjuster for optical shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple functional modules are used in head-mounted electronic devices, then imaging and radar sensing functions are achieved, but device size becomes large
Solution Approach 1:
The patent combines antenna elements and image sensing elements into a single integrated module, where the antenna elements perform radar sensing functions and the image sensing elements perform imaging functions. This merging of multiple functional modules into one compact unit reduces the overall device size while maintaining both imaging and radar capabilities.
Solution Approach 2:
The integrated module serves multiple functions simultaneously - the antenna elements provide radar beam sensing in various directions, while the image sensing elements capture reflected light for imaging. This multi-functional design allows a single module to replace what would traditionally require separate radar and imaging components.
2Device complexity
If the number of antenna elements is limited, then device complexity is reduced, but radar beam coverage and diversity characteristics are limited
Solution Approach 1:
The patent arranges antenna elements at different relative positions and orientations within the integrated module, creating three-dimensional spatial distribution of sensing beams. This spatial arrangement in multiple dimensions allows the system to achieve comprehensive radar beam coverage and diversity characteristics without requiring a large number of antenna elements.
3Volume of moving object
If antenna elements and image sensing elements are integrated into a single module, then device size is reduced, but integration complexity increases
Solution Approach 1:
The integrated module is designed with distinct functional regions - antenna elements are positioned separately from image sensing elements, with each component maintaining its independent function. This segmentation within integration allows for manageable complexity by organizing components in a structured manner while achieving compact size.
