Solution Overview

Problem

Existing filling station technologies often cause damage or breakage of fragile products like eggs, apples, and glass objects during filling due to forceful placement and inadequate consideration of product size and shape, leading to inefficient packing and potential breakage.

Innovation Solution

The use of airflow generated by a fluid flow generator, such as a fan, to distribute products evenly within a container, acting as a cushion between the products and the container bottom, and between products themselves, preventing collision and breakage, while allowing for adjustable airflow force based on product weight to achieve optimal packing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If products are placed with force onto each other to achieve efficient filling, then filling speed and productivity are improved, but product breakage and damage increase

Engineering Contradiction:
Improvefilling speedVSAvoidproduct breakage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

A fluid flow (air current) is introduced as an intermediary between the feed and the products in the container. The fluid flow gently propels products into the container and distributes them evenly, replacing direct mechanical contact and forceful placement. This mediator allows efficient filling while preventing product breakage by eliminating impact forces.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical placement mechanisms (robots, conveyors that drop products) with a fluid dynamic system. Instead of using mechanical force to place products, the system uses controlled fluid flow to transport and distribute products, substituting mechanical action with aerodynamic action to reduce damage.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If products are placed one by one to avoid breakage, then product damage is reduced, but filling time and loss of time increase

Engineering Contradiction:
Improveproduct breakageVSAvoidfilling time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The fluid flow operates continuously to transport and distribute multiple products simultaneously into the container. Unlike sequential placement methods, the continuous fluid stream handles multiple items at once, maintaining uninterrupted filling action while keeping products separated by the fluid medium, thus reducing both time and breakage.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent employs pneumatic principles by using a controlled fluid flow (air current) to transport and distribute products. This pneumatic system allows multiple products to be moved and placed simultaneously without direct mechanical contact, achieving fast filling while preventing breakage through the gentleness of fluid interaction.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Productivity

If strong fluid flow is used to distribute products quickly, then productivity is improved, but product damage from fluid force increases

Engineering Contradiction:
Improvedistribution speedVSAvoidproduct damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The fluid flow parameters (velocity, pressure, direction) are made dynamically adjustable based on product characteristics and filling requirements. The system adapts the fluid flow strength in real-time, using stronger flow for robust products and gentler flow for fragile items, optimizing both productivity and product protection through dynamic control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters of the fluid flow (velocity, pressure, flow rate) to match product fragility and filling needs. By adjusting these parameters, the system achieves high productivity with appropriate flow strength while preventing damage through reduced flow intensity for fragile products, demonstrating parameter optimization.

Inventive Principle:
Principle #35Parameter changes
