Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product conveyor systems struggle to efficiently convey a wide variety of products, particularly light ones, due to sliding issues during acceleration or deceleration, which affects reliability and capacity.
Innovation Solution
The system incorporates a blowing device that generates an air stream to force products against the carrying surface, combined with a control device that manages the supply drive and blowing device to ensure precise positioning and movement of products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveying speed is increased to improve capacity, then productivity increases, but light products slide relative to the carrying surface during acceleration or deceleration, worsening reliability
Solution Approach 1:
The patent applies pneumatic principles by introducing a blowing device that generates an air stream to force light products against the carrying surface during acceleration and deceleration phases. This pneumatic action prevents sliding without requiring mechanical contact or increasing friction, allowing high conveying speeds to be maintained while ensuring reliable product positioning.
2Reliability
If mechanical friction is increased to prevent sliding, then product stability improves, but the complexity of the system increases due to additional mechanical components
Solution Approach 1:
The patent replaces potential mechanical solutions (such as friction-based mechanisms or mechanical clamps) with a pneumatic field-based approach. The blowing device uses controlled air streams to achieve product stabilization, eliminating the need for complex mechanical friction-based systems while maintaining product stability during conveying operations.
3Productivity
If the conveying speed is increased to improve capacity, then productivity increases, but light products may come away from the carrying surface and land next to the conveyor, worsening reliability
Solution Approach 1:
The patent applies preliminary anti-action by using the blowing device to counteract the tendency of light products to lift off the carrying surface during acceleration and deceleration. The air stream is directed to press products against the surface in advance of any potential lifting, preventing the harmful effect before it occurs and ensuring reliable product transfer even at high conveying speeds.
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
This solution effectively conveys even light products by preventing sliding, enhancing system reliability, and increasing capacity by allowing higher conveying speeds while maintaining reliable product transfer.
Implementation Method 1
