Reusable Bottle Rental System for Sanitation and Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public places often lack access to sanitary and reliable hydration solutions, leading to unnecessary waste from disposable cups and bottles, and users may be unsure about the safety of water from unsanitary sources.
Innovation Solution
A system that allows users to rent sanitized reusable bottles, which can be filled with liquid and returned for sanitization and reuse, reducing waste and ensuring safe hydration through a bottle sharing program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable cups or bottles are used for water access in public places, then immediate hydration is provided, but waste is generated and sanitation reliability is compromised
Solution Approach 1:
The system recovers reusable bottles from users after use, sanitizes them, and returns them to the circulation pool. This eliminates the need for disposable bottles while maintaining sanitation through centralized processing, directly resolving the contradiction between waste reduction and sanitation reliability.
Solution Approach 2:
Users simply return their bottles to the station, and the automated system handles sanitization, inspection, and redistribution. This self-service model ensures consistent sanitation standards without requiring user involvement in the cleaning process, maintaining both reliability and waste reduction.
2Quantity of substance
If water fountains or water coolers are used for hydration, then water access is provided, but sanitation safety is uncertain and additional containers are needed
Solution Approach 1:
The reusable bottle acts as an intermediary between the user and the water source. The bottle is sanitized at the station, creating a controlled intermediate step that ensures water safety while allowing users to transport hydration away from potential unsanitary water sources, eliminating the need for additional containers.
3Loss of substance
If a bottle sharing program with sanitization is implemented, then waste is reduced and sanitation is ensured, but system complexity increases
Solution Approach 1:
The system uses automated bottle handling, inspection, and sanitization equipment that operates without human intervention. Users simply insert or return bottles to the station, and the automated system manages the entire process, reducing operational complexity while maintaining waste reduction and sanitation benefits.
4Loss of substance
If reusable bottles are provided through rental, then waste is minimized and sanitation is maintained, but user account management and tracking are required
Solution Approach 1:
The system uses RFID tags, QR codes, or other identification methods to automatically track bottles with users. The control system receives feedback about bottle locations and statuses, automatically managing rentals and returns without requiring manual account management, thus minimizing waste while keeping operational complexity low.
Data Source
AI summary
Techniques for providing a reusable filled bottle are provided. A stations receives a bottle request from a user and uses information from the request to select and associate a sanitized bottle to the user. The user is charged for a bottle rental and provided with a filled reusable bottle. The user may also return the bottle to the station to have the bottle refilled or return the bottle such that the bottle rental is completed and the bottle no longer associated with the user.
