Dual-Axle Linkage Detection Structure for Multi-Sensor Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-purpose scanning devices with multiple sensors result in high costs, necessitating a detection structure that reduces the number of sensors while maintaining functionality.
Innovation Solution
A dual-axle linkage detection structure comprising a first object, a second object, a sensor body, and a shielding element, where the sensor body is disposed on the first object and the shielding element is on the second object, allowing a single sensor to detect actions by positioning the shielding element at different detecting positions as the objects move relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are disposed on the flatbed scanner and automatic document feeder to detect actions, then the detection functionality is improved, but the total cost increases
Solution Approach 1:
The patent combines the detection functions for the flatbed scanner and automatic document feeder into a single sensor system. The sensor body with detecting positions and shielding element works together to detect actions of both the first object (flatbed scanner) and second object (automatic document feeder), eliminating the need for separate sensors on each component.
Solution Approach 2:
The single sensor body is designed with multiple detecting positions that can detect actions of different objects. The sensor serves multiple functions by detecting both the flatbed scanner actions and automatic document feeder actions through its multiple detecting positions, making it a universal detection device.
2Reliability
If sensors are disposed on multiple components to detect actions, then the detection coverage is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple detection functions into a single integrated sensor system. The sensor body with multiple detecting positions and the shielding element work together to provide comprehensive detection coverage for both the flatbed scanner and automatic document feeder, reducing the overall complexity of the sensor configuration.
Solution Approach 2:
The sensor body utilizes multiple detecting positions arranged in different spatial dimensions to detect actions of different objects. By organizing detecting positions in a multi-dimensional arrangement, the single sensor achieves comprehensive detection coverage that would otherwise require multiple separate sensors.

AI summary
A dual-axle linkage detection structure includes a first object, a second object, a sensor body, and a shielding element. The first object is movably connected to a base. The second object is movably connected to the first object. The sensor body is disposed on the first object and includes detecting positions. The shielding element includes a shielding part. When the second object covers the first object and the first object covers the base, the shielding part moves into the detecting position. When the second object moves away from the first object, or when the first object moves away from the base and drives the shielding element to rotate, the shielding part moves out of the detecting position.
