Coin Dispenser Step Section Shaft Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin dispensing apparatuses face difficulties in easily adjusting the distance between the base plate and the rotating disk to accommodate coins of varying thickness, often requiring cumbersome spacer changes or limited adjusting ranges, which complicates the operation and stability of coin dispensing.
Innovation Solution
A coin dispensing apparatus featuring a step section with multiple steps around an inserting hole for the rotating shaft member, allowing for adjustable attachment to adapt to different coin thicknesses, with a spiral staircase design enabling easy adjustment and stable coin dispensing without the need for additional intervening members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spacer is added around the rotating shaft to adjust the distance between the base plate and the rotating disk, then the apparatus can adapt to different coin thicknesses, but the operation becomes troublesome and the device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the rotating shaft itself adjustable in position along its axis. The shaft can be moved to different heights to accommodate various coin thicknesses, transforming a static structure into a dynamic one. This allows the distance between the base plate and rotating disk to be adjusted simply by repositioning the shaft, eliminating the need for separate spacers and reducing operational complexity.
Solution Approach 2:
The rotating shaft is designed to serve multiple functions: it supports the rotating disk, transmits rotational motion, and simultaneously acts as the adjustment mechanism for adapting to different coin thicknesses. By integrating the adjustment function into the shaft itself rather than requiring separate spacers, the device achieves multi-functionality and reduces the number of components needed.
2Reliability
If the conical section is used to prevent removal of the rotating shaft, then the shaft can be secured, but the adjusting range of the rotating disk is limited by the diameter of the rotating shaft and the angle of the conical section
Solution Approach 1:
The patent segments the rotating shaft into functionally distinct sections: an upper portion with a conical section for securement and prevention of removal, and a lower portion that serves as the adjustment mechanism for the rotating disk position. This segmentation allows the shaft to simultaneously provide both security through the conical section and extensive adjustment range through the adjustable lower portion, resolving the contradiction between reliability and adaptability.

AI summary
A coin dispensing apparatus is provided that has features to easily adjust the distance between the base plate and the rotating disk and to adapt to the thickness of the coins. The coin dispensing apparatus includes a disk (102) which separates coins one by one. A coin base (104) supports the coins which are moved by the disk. A body (100) includes the base and a step section (149) which provides different distances to the base to adapt to the thickness of the coins. A rotating shaft member (160) is selectively attached to the step section and can be adjusted to the body. The rotating shaft member for rotating the disk is selectively attached at the step section in stages. Therefore the distance between the disk and the base is adjusted to adapt the thickness of coin.
