Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coin conveyance devices face issues with durability and assembly complexity due to the wear of resin-made pushing bodies and the need for different rotating bodies based on conveyance passage curvature, leading to increased components and potential assembly errors.
Innovation Solution
A coin conveyance device with rotating bodies featuring pins and support protrusions, where pins have large and small diameter portions, and are fitted into pin holes, allowing for easy assembly and improved durability by reducing wear and enabling universal rotation direction compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resin-made pushing bodies are used, then the device is easy to manufacture, but the pushing bodies wear by coming into contact with coins
Solution Approach 1:
The pushing body is constructed as a composite structure combining resin material with a metallic round bar. The resin provides ease of manufacture and cost-effectiveness, while the metallic round bar embedded in the resin provides wear resistance and durability when contacting coins, thus resolving the contradiction between ease of manufacture and reliability.
2Reliability
If different kinds of rotating bodies are prepared for right-handed and left-handed rotations and for curved and flat conveyance passages, then the pushing bodies can be optimized for each position, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The pushing body design with the metallic round bar embedded in resin creates a universal component that can be used across different rotating bodies regardless of their rotation direction (right-handed or left-handed) or conveyance passage type (curved or flat). This multi-functional design eliminates the need for different kinds of rotating bodies, reducing component variety and simplifying assembly while maintaining optimized performance.
3Stability of the object's composition
If the metallic round bar or sheet metal is secured firmly on the rotating body to make them into one unit, then the pushing body structure is stable, but the assembly process becomes more complex and error-prone
Solution Approach 1:
The metallic round bar and resin material are merged into a single integrated pushing body component where the metallic bar is embedded within the resin. This merging creates a stable structural composition while simplifying assembly, as the combined component is installed as one unit rather than requiring separate attachment steps for the metallic bar and resin, thus reducing assembly complexity and errors.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the durability of pushing bodies and simplifies assembly by using interchangeable pins and support protrusions, ensuring smooth coin conveyance and reducing the risk of assembly errors.
Implementation Method 1
The pushing bodies come into contact with the circumferential surface of a coin, whose movement direction is guided by sidewalls forming the conveyance passage, and push the coin upward from a lower side along with the rotation of the rotating body
Implementation Method 2
The rotating bodies arranged alternately in the up-down direction feed a coin in such a way that one of the rotating bodies receives a coin from the rotating body disposed diagonally below and transfers the coin to the rotating body disposed diagonally above

AI summary
A coin conveyance device that feeds multiple coins stored in a storage container one by one and conveys the fed coin upward uses rotating bodies including pushing bodies for pushing a coin. The pushing bodies which are arranged opposed to each other about the center of rotation of each rotating body each include: a metallic pin that comes into contact with a coin; and a resin-made support protrusion that supports the pin. The support protrusion includes a concave portion corresponding to the shape of the circumferential surface of the pin. The pin is inserted into a pin hole adjacent to the support protrusion, and its side surface is supported by the concave portion of the support protrusion. A force applied when the pin pushes the coin is received by the support protrusion, whereby the durability of the pushing body is improved.
