On-Demand Water Kiosk Using Compostable Filled Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional liquid containers, such as plastic bottles, contribute significantly to plastic waste due to their inefficiency and lack of compostability, posing ecological damage and violating the need for environmentally friendly materials that can withstand distribution channels.
Innovation Solution
An automated liquid dispensing device that uses compostable materials like wood or bamboo pulp for the container shell and a poly-lactic acid pouch, capable of storing, filling, and sealing bottles on demand, while integrating data collection and efficient stacking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plastic containers are used for liquid distribution, then the containers can withstand distribution channels and have long shelf life, but they cause massive plastic waste and ecological damage
Solution Approach 1:
The patent changes the material parameter from traditional plastic (PET, HDPE) to compostable materials (wood pulp, bamboo pulp, PLA, PHA, PBAT). This parameter change allows the container to maintain structural integrity for distribution while being biodegradable, thus resolving the contradiction between durability and plastic waste generation.
Solution Approach 2:
The patent employs composite material structures, such as combining compostable shell materials with compostable lining materials (PLA, PHA, PBAT). These composite structures provide the necessary mechanical strength for distribution channels while ensuring the entire container can be composted, addressing both reliability and environmental harm concerns.
2Object-generated harmful factors
If compostable materials are used for containers, then plastic waste is reduced, but the containers cannot withstand violent distribution channels
Solution Approach 1:
The patent uses composite material structures where compostable materials (wood pulp, bamboo pulp shells combined with PLA, PHA, or PBAT linings) work together to provide both compostability and the necessary strength for distribution. The composite structure maintains structural integrity during handling and transport while ensuring the container can be composted after use.
Solution Approach 2:
The patent implements preliminary sealing mechanisms that close the container bottom before filling. This preliminary action protects the compostable materials from degradation and contamination during storage and distribution, ensuring the container maintains its strength and integrity throughout the distribution channel while remaining compostable.
3Productivity
If automated dispensing devices are implemented, then filling and sealing efficiency is improved, but device complexity increases
Solution Approach 1:
The automated dispensing device is segmented into distinct functional modules: container storage, bottom sealing mechanism, filling mechanism, and dispensing mechanism. This segmentation allows each module to perform its specific function efficiently while simplifying the overall system design and maintenance, resolving the contradiction between productivity and device complexity.

AI summary
In one embodiment, a method for dispensing a filled container comprises removing a single container from a stack of containers within a chassis, filling the single container with filtered water within the chassis, sealing the single container within the chassis, and dispensing the single container from the chassis. In another embodiment, a system for dispensing a filled container comprises a chassis, a stack of containers within the chassis, and an automated mechanism within the chassis to remove a single container from the stack of containers, fill the single container with filtered water, seal the single container, and dispense the single container from the chassis.
