Cash Box Sensor Merging for Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cash boxes for deposit and withdrawal machines have high purchase costs and occupy large spaces, making them unsuitable for miniaturization due to the need for multiple sensors to detect the positions of the guiding plate and pickup roller.
Innovation Solution
A cash box design that uses a single sensor to detect the positions of the guiding plate and pickup roller, with the sensor outputting different signals based on the plate's feeding and pickup positions, allowing for reduced complexity and space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are used to detect the positions of the guiding plate and pickup roller, then the detection reliability is improved, but the device complexity and occupied space increase
Solution Approach 1:
The patent combines multiple detection functions into a single sensor by integrating the guiding plate and pickup roller positions onto one detection component. This merging approach maintains detection reliability while reducing device complexity and occupied space, directly resolving the technical contradiction between using multiple sensors versus minimizing system complexity.
Solution Approach 2:
The single sensor is designed to perform multiple detection functions simultaneously - detecting both the guiding plate position and the pickup roller position. This multi-functionality allows one sensor to replace what would traditionally require multiple sensors, thereby reducing device complexity while maintaining comprehensive detection capability.
2Measurement precision
If multiple sensors are used to detect the positions of the guiding plate and pickup roller, then the detection precision is improved, but the occupied space increases
Solution Approach 1:
The patent merges multiple detection functions into a single sensor assembly, reducing the total occupied space while maintaining detection precision. By consolidating the detection of guiding plate and pickup roller positions into one sensor, the spatial footprint is minimized without sacrificing measurement accuracy.
Solution Approach 2:
The detection system utilizes spatial arrangement in different dimensions - the sensor is positioned to detect both components through strategic geometric configuration. This dimensional approach allows one sensor to capture multiple position data points without requiring additional linear space, effectively resolving the contradiction between detection precision and occupied area.

AI summary
Disclosed are a cash box and a banknote processing device using the same. The cash box includes: a guiding plate, configured to guide a banknote to enter a banknote storage chamber; a pickup roller, configured to output the banknote; and a sensor, configured to detect a position of the guiding plate and a position of the pickup roller. When the guiding plate is in a banknote feeding position or the pickup roller is in a banknote pickup position, the sensor outputs a first signal. When the guiding plate deviates from the banknote feeding position and the pickup roller deviates from the banknote pickup position, the sensor outputs a second signal, wherein the first signal is different from the second signal.
