Banknote Feeding Partition Wall Prevents Misinsertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Banknote processing devices face issues with mistaken insertion into non-holding areas due to the widening gap between the bill press and the front wall, which can lead to device malfunction, and existing solutions like electric shutters increase complexity.
Innovation Solution
A medium processing device design that includes a holding section with a medium press section capable of moving between end walls and an opening-out section that spans into the non-holding area, preventing mistaken insertion without additional mechanisms like electric shutters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bill press is slid toward the rear to approach the pick-up rollers, then the banknotes can be pressed against the pick-up rollers and fed out, but the area between the bill press and the front wall (non-holding area) becomes wider, creating risk of mistaken insertion
Solution Approach 1:
A partition wall is introduced as an intermediary structure between the holding area and the non-holding area. This partition wall physically separates the two regions, preventing mistaken insertion of banknotes into the non-holding area while allowing the bill press to slide freely for its feeding operation. The partition wall acts as a mediator that resolves the conflict between operational movement and prevention of harmful insertion.
Solution Approach 2:
The holding section is segmented into two distinct areas: a holding area where banknotes are inserted and held, and a non-holding area where the bill press operates. The partition wall creates this segmentation, ensuring that banknotes can only be inserted into the holding area while the bill press can move independently in the non-holding area for its feeding function.
2Object-affected harmful factors
If an electric shutter is added to prevent mistaken insertion, then the insertion port can be closed, but the device complexity increases due to additional drive sections and control mechanisms
Solution Approach 1:
The shutter mechanism is extracted and replaced with a simpler partition wall structure. Instead of using a complex electric shutter system with motors and controls, the partition wall provides a static or simply structured barrier that prevents mistaken insertion without requiring additional drive sections or control mechanisms, thus reducing device complexity while maintaining the protective function.
Solution Approach 2:
The partition wall serves as a simple, inexpensive structural element compared to a complex electric shutter system. It provides the necessary protection against mistaken insertion through its physical presence and positioning, eliminating the need for expensive and complex motorized shutter mechanisms.

AI summary
A medium processing device including a holding section that includes an opening forming a medium insertion port, and that holds a medium inserted through the insertion port, a medium press section that is capable of moving between a first end side wall and a second end side wall of the holding section, and that presses the medium inserted through the insertion port against the second end side wall of the holding section, and an opening-out section that spans between the medium press section and the first end side wall of the holding section, and that opens out in a medium non-holding area between the medium press section and the first end side wall of the holding section accompanying movement of the medium press section from the first end side to the second end side of the holding section in order to press the medium inserted into a medium holding area between the medium press section and the second end side wall of the holding section against the second end side wall of the holding section.
