Biodegradable Trash Receptacle With Adhesive Inner Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trash cans without liners face issues of leakage, spillage, and cumbersome disposal, especially when dealing with wet waste, and existing solutions like disposable containers are not recyclable or convenient for multiple uses.
Innovation Solution
A biodegradable disposable trash receptacle system comprising a paper outer member and a thin, water-resistant plastic inner member, glued together with a drawstring for easy closure and disposal, providing a recyclable and sanitary solution for both dry and wet waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a conventional trash can without a liner is used, then the container can be reused multiple times, but leakage and spillage occur especially when dealing with wet waste
Solution Approach 1:
The trash can system is divided into two separate components: a reusable outer container and a disposable inner liner. The liner can be removed and replaced independently when full or contaminated, allowing the outer container to be reused while preventing leakage and spillage through the liner's contained structure.
Solution Approach 2:
A disposable biodegradable liner is introduced as a temporary, low-cost component that performs the containment function for wet waste. The liner is discarded after single use, eliminating the need to clean the reusable outer container and preventing leakage issues associated with reused containers.
2Reliability
If a disposable container is used, then leakage and spillage are prevented, but the container cannot be reused and must be disposed of after one use
Solution Approach 1:
The system separates the reusable outer container from the disposable inner liner. The outer container maintains its structural integrity for multiple uses, while the inner liner provides reliable leakage prevention for each single use, combining the benefits of both approaches.
Solution Approach 2:
The system combines two different materials with different lifecycles: a durable material for the outer container that can be reused, and a biodegradable material for the inner liner that provides reliable containment and is disposed of after one use. This composite approach resolves the contradiction between reusability and leakage prevention.
3Ease of manufacture
If liners are not used in garbage containers, then cleaning becomes easier, but wet garbage contents cause leaking issues
Solution Approach 1:
A disposable biodegradable liner is used to contain wet garbage contents, preventing leakage while eliminating the need for cleaning the outer container. The liner is discarded after single use, maintaining ease of maintenance while ensuring reliable containment.
4Ease of manufacture
If unsupported garbage bags are used, then cost is reduced, but the bags are easily punctured or tipped over causing spillage
Solution Approach 1:
The disposable biodegradable liner is combined with a supportive outer container structure. The outer container provides mechanical support to prevent tipping and puncturing, while the inner liner contains the garbage contents, together achieving spillage prevention at low cost.
