Solution Overview
Problem
Conventional coordinate locating devices are limited in their ability to locate the coordinates of multiple objects, often requiring multiple image sensors, which increases manufacturing costs and restricts their applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image sensors are used to detect multiple objects, then the ability to locate multiple objects is improved, but the manufacturing cost increases greatly
Solution Approach 1:
The patent merges the functions of multiple image sensors into a single image sensor by combining optical paths using beam splitters and mirrors. This allows one image sensor to capture images from multiple viewing angles simultaneously, enabling multi-object detection without requiring multiple separate sensors, thus reducing manufacturing cost while maintaining the ability to locate multiple objects
Solution Approach 2:
The single image sensor is designed to perform multiple functions by detecting objects from different angles through optical path combination. The system makes one sensor universal by enabling it to capture multiple spatial perspectives, replacing what would traditionally require multiple specialized sensors
2Ease of manufacture
If a single image sensor is used, then the manufacturing cost is reduced, but the ability to locate multiple objects is limited
Solution Approach 1:
The patent adds the dimension of multiple viewing angles to a single image sensor's capability. By using beam splitters and mirrors to create multiple optical paths, the system enables one sensor to detect objects from different spatial dimensions, transforming it from a single-point detector into a multi-perspective detection system
