Segmented Coin Changer Funnel for Quick Acceptor Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin changer designs require technicians to move or disassemble the coin chute to remove the acceptor portion while installed in a vending machine, increasing the time and complexity of maintenance.
Innovation Solution
A coin changer design with a rear funnel portion attached to the coin changer body and a front funnel portion attached to the acceptor, allowing the acceptor to be easily removed by rotating and lifting it without needing to move the coin chute, as the rear funnel portion does not interfere with the chute's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the chute extends into the funnel to prevent jams, then coin routing reliability is improved, but acceptor removal complexity increases
Solution Approach 1:
The funnel is divided into two separate portions: a rear funnel portion attached to the coin changer body and a front funnel portion attached to the acceptor. This segmentation allows the front funnel portion to extend into the chute path for reliable coin routing while the acceptor can be easily removed by detaching only the front funnel portion, without requiring chute disassembly.
2Ease of repair
If the chute is moved or disassembled to remove the acceptor, then acceptor replacement is enabled, but maintenance time increases
Solution Approach 1:
The funnel is segmented into rear and front portions with different attachment configurations. The front funnel portion is attached to the acceptor and can be easily detached, while the rear funnel portion remains attached to the coin changer body. This allows technicians to remove and replace the acceptor quickly without moving or disassembling the chute, significantly reducing maintenance time.
