Solution Overview

Problem

Vending machines often experience issues with the smooth transition of products from a column to a cup, leading to rough handling and potential failures in product delivery due to tilting and bridging, which can result in failed exchanges from the tray to the dispenser.

Innovation Solution

The implementation of a tilting cup mechanism that adjusts its angle to match the product's path of motion, combined with a pusher assembly featuring a spring and damper to control the velocity of product movement, ensures a smooth transition from the column to the cup, preventing tilting and bridging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional delivery system is used to move products from column to cup, then the delivery mechanism is simple, but the product transition is rough causing tilting and bridging

Engineering Contradiction:
Improveproduct delivery reliabilityVSAvoiddelivery system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cup is designed to tilt dynamically during the product transfer process. The cup starts in a first orientation aligned with the column, then tilts to a second orientation to facilitate smooth product entry, and finally returns to a third orientation for stable product holding. This dynamic orientation change eliminates rough transitions, tilting, and bridging of products during delivery.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the orientation parameter of the cup throughout the delivery cycle. The cup transitions between multiple orientations (first, second, and third orientations) to optimize product transfer at different stages. This parameter change enables smooth product flow while maintaining delivery reliability.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the cup tilts to match the product path of motion, then the product transition becomes smooth preventing tilting and bridging, but the device complexity increases

Engineering Contradiction:
Improveproduct transfer smoothnessVSAvoidcup mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cup tilts dynamically during the product transfer process. The cup starts in a first orientation aligned with the column, then tilts to a second orientation to facilitate smooth product entry, and finally returns to a third orientation for stable product holding. This dynamic orientation change eliminates rough transitions, tilting, and bridging of products during delivery.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tilting mechanism is integrated with the cup structure itself, combining the product receiving function and the tilting motion into a single unified component. This merging eliminates the need for separate complex tilting mechanisms while achieving smooth product transfer.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If a pusher assembly with spring and damper is used to control product velocity, then the product transfer becomes stable and efficient, but the device complexity increases

Engineering Contradiction:
Improveproduct transfer efficiencyVSAvoidpusher assembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pusher assembly uses a spring to provide controlled pushing force and a damper to regulate the velocity parameter of product movement. This combination allows the system to maintain optimal product transfer speed, preventing both tilting and bridging while ensuring stable and efficient product delivery from the column to the cup.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The damper component provides beforehand cushioning by controlling the velocity of the pusher assembly before product transfer issues can occur. This prevents excessive speed that would cause tilting and bridging, while the spring ensures sufficient force is available to move products reliably.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
