Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prepackaged coffee charges have high environmental impact due to non-biodegradable container materials and lack mechanical stability during insertion and ejection.
Innovation Solution
A compostable container body made from vegetable fiber pulp derived from seasonal crop waste, with a Kappa number less than 2, and a structure that allows at least one face to be continuous and compact while the other face is discontinuous and wrinkled, enabling filtration and plastic deformation without breaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flexible material like filter paper is used for the container body, then the environmental impact is reduced (biodegradable and compostable), but the mechanical stability deteriorates (creates problems during insertion and ejection)
Solution Approach 1:
The patent changes the physical-chemical parameters of the container body by using vegetable fiber pulp with Kappa number less than 5%, creating a material that is both mechanically stable and compostable. This parameter change resolves the contradiction by achieving sufficient mechanical strength for insertion and ejection while maintaining biodegradability and compostability.
Solution Approach 2:
The patent employs composite material structure by combining vegetable fiber pulp with specific lignin content requirements (Kappa number < 5%) to create a container body that integrates both mechanical stability and environmental compatibility. The composite nature of the material allows it to exhibit both structural integrity and compostability.
2Weight of moving object
If the container body walls are made thin and light, then the weight is reduced, but the mechanical strength deteriorates (risk of breakage during operation)
Solution Approach 1:
The patent optimizes the physical parameters of the vegetable fiber pulp by controlling the Kappa number (lignin content) to be less than 5%, which enables the creation of thinner, lighter container walls that maintain sufficient mechanical strength. This parameter optimization allows weight reduction without compromising structural integrity during insertion, ejection, and beverage extraction.
3Object-affected harmful factors
If the container body is made from compostable material, then the environmental impact is reduced, but the filtration performance deteriorates (requires additional considerations for perforating walls)
Solution Approach 1:
The patent modifies the chemical composition parameters of the container body by specifying vegetable fiber pulp with Kappa number less than 5%, which inherently provides filtration capabilities. This parameter change enables the compostable material to simultaneously achieve reliable filtration performance, allowing the container walls to retain coffee grounds while permitting beverage extraction without requiring additional perforation considerations.
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 results in a lighter, thinner, yet stronger container body that is fully compostable, reduces environmental impact, and ensures efficient filtration and infusion without material loss or container breakage.
Implementation Method 1
Permeation of the infusion through the walls of the container body is achieved by working the surface of the container body walls
Implementation Method 2
the walls of said container body are able to act as a filter under the conditions of use, i.e., during coffee extraction
Implementation Method 3
which have one face that is continuous and compact and the other face that is discontinuous and wrinkled
Implementation Method 4
In addition, plastic deformation of at least one wall of the container body is provided so as to promote permeation

AI summary
Prepackaged charge of edible material powder for use in a beverage preparation system, comprising a rigid container body made of paper or cardboard, comprising a continuous side wall and a bottom wall made of piece with each other, obtained by processing vegetable fiber pulp derived from waste from the primary processing of seasonal crops such as sugarcane, rice cotton, hemp, sorghum, bamboo or the like, alone or in composition with each other, in which Kappa number of the vegetable fiber pulp is less than 2, and in which the walls of said container body are made in such a way that at least one face of said walls is continuous and compact, while the other face is discontinuous and wrinkled are capable of acting as a filter upon use, allowing the passage of infusion.
