Packaging Bag Inner Surface Charge Retains Fine Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional excrement treatment materials experience fine particles being released outside the packaging bag due to collisions during transportation, leading to inconvenience and contamination.
Innovation Solution
A packaging bag with an inner surface charge amount greater than the outer surface charge amount is used to attract and retain fine particles, preventing their release when grains are removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple grains are housed collectively in one packaging bag for convenient transportation and storage, then transportation and storage convenience is improved, but fine particles are generated through grain collisions and accumulate in the packaging bag, leading to release outside the bag when grains are removed
Solution Approach 1:
The patent introduces an intermediary substance (electrified packaging bag material) that mediates between the grains and the packaging bag. The electrified inner surface acts as a mediator that actively captures and holds fine particles, preventing their release when grains are removed. This resolves the contradiction by adding a mediating element that addresses the fine particle issue without changing the collective housing approach.
Solution Approach 2:
The patent changes the physical parameter of the packaging bag by electrifying its inner surface, creating a charged surface that can attract and hold fine particles through electrostatic forces. This parameter change (electrification) allows the packaging bag to actively retain fine particles while maintaining the convenience of collective grain housing, thus resolving the contradiction between ease of operation and prevention of fine particle release.
2Quantity of substance
If grains are housed in a packaging bag, then storage efficiency is improved, but grain collisions during transportation cause peeling and fine particle generation
Solution Approach 1:
The patent converts the harmful effect of grain collisions (which generate fine particles) into a beneficial outcome. By electrifying the packaging bag's inner surface, the fine particles that would normally be harmful contaminants are instead captured and retained on the charged surface. This transforms the collision-induced fine particle generation from a loss problem into a controlled phenomenon where particles are harmlessly held on the packaging bag interior.

Function Achieved in This Case
The solution effectively keeps fine particles within the packaging bag, enhancing transportation and handling safety by minimizing external leakage and contamination.
Implementation Method 1
