Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current one-serve directly-brewing type beverage carriers made from petroleum-based plastics face issues with environmental sustainability, health safety concerns due to high-temperature beverage exposure, and inefficient manufacturing processes due to inconsistent nesting and assembly challenges.
Innovation Solution
A paper-made container is formed using a wet-fiber paper-molding process, integrated with protrusive portions for precise nesting and assembly, ensuring biodegradability and biocompostability, and a clearance fit for accurate component picking, addressing the environmental and manufacturing inefficiencies of existing carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If petroleum-based plastic containers are used for beverage carriers, then the containers can be manufactured with good structural integrity and reusability, but they cause environmental pollution and health safety concerns when discarded after use
Solution Approach 1:
The patent changes the material parameter from petroleum-based plastic to plant fiber-based material, transforming the carrier from non-biodegradable to biodegradable while maintaining structural integrity through optimized fiber composition and processing methods
Solution Approach 2:
The patent enables the carrier to be naturally decomposed and returned to the environment after use, eliminating the need for recycling infrastructure and converting the waste disposal problem into a natural recovery process through biodegradation
2Volume of moving object
If plastic containers are nested in cup-stacking alignment for conveying, then space efficiency is improved, but inconsistent nesting depth and fitting scale cause assembly line inefficiency and container loss
Solution Approach 1:
The patent incorporates positioning structures and standardized fitting features during the container manufacturing stage, enabling consistent nesting alignment before the containers reach the assembly line, thereby eliminating assembly line inefficiencies
Solution Approach 2:
The patent employs suction cups or pneumatic gripping mechanisms on the assembly line to securely hold and extract nested containers, overcoming the inconsistency in nesting depth and fitting scale through controlled pneumatic force application
3Stability of the object's composition
If nested depth and fitting scale between plastic containers are too tight, then nesting stability is improved, but automatic component-picking equipment cannot accurately draw out individual containers
Solution Approach 1:
The patent divides the container structure into standardized segments with defined interface features, allowing consistent nesting depth and fitting scale that provide both stability and accessible extraction points for automated equipment
Solution Approach 2:
The patent replaces manual nesting and extraction operations with automated pneumatic or robotic systems that can precisely control the forces and positions required for accurate container extraction from nested stacks

AI summary
The present invention discloses a carrier used for preparing beverage and a method for fabrication thereof. The carrier has primarily components comprising a sealing lid, a filter and a paper-made container, wherein by mold assembly of wet-fiber paper-molding process, solid geometric shape of the paper-made container is integrally formed, and by demolding of the paper-made container along a demolding direction corresponding to the mold assembly, annular cup wall of the paper-made container is laterally formed with at least one protrusive portion, having central axis paralleling with the demolding direction, and after a number of the paper-made containers are one-by-one nested in alignment into a stack assembly, the at least one protrusive portion acts on ensuring the respective paper-made container is one-by-one drawn from the number of paper-made containers of the stack assembly while passing through picking of component-assembling production line, thereby assembling corresponding components to constitute the respective corresponding carrier.
