Disposable Bag Air Release Flap for Odor and Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a discrete and hygienic means to store and conceal food waste until a proper waste receptacle is available, as existing methods like spitting on the ground or using paper napkins are not suitable for maintaining a clean environment.
Innovation Solution
A disposable bag with an air release flap, a tear line, and multiple seals that allows air to exit while preventing odor, enabling users to inflate, store waste, and then deflate and fold the bag for convenient disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the bag is sealed to prevent odor and contain waste, then hygiene is improved, but air trapped inside causes inflation and discomfort
Solution Approach 1:
The patent extracts the air release function from the sealed system by providing a dedicated air release flap that is separate from the waste containment seals. This allows air to be removed from the bag while maintaining the密封 integrity for odor prevention, resolving the contradiction between hygiene and internal pressure.
Solution Approach 2:
The air release flap acts as an intermediary element between the sealed waste containment system and the external environment. It provides a controlled pathway for air escape while maintaining the overall seal integrity, enabling both odor containment and pressure relief simultaneously.
2Ease of operation
If the opening is made large to facilitate waste disposal, then ease of operation is improved, but the bag becomes difficult to conceal and dispose discretely
Solution Approach 1:
The opening mechanism is segmented into multiple components: a first opening for initial waste disposal, a tear line for creating a second opening, and a resealable flap. This segmentation allows the bag to provide easy access when needed while maintaining a compact, concealable form when closed, resolving the contradiction between operational ease and discreteness.
Solution Approach 2:
The bag features dynamic opening mechanisms where the first opening can be sealed with a first seal, and a second opening can be created by tearing along the tear line. This dynamic structure allows the opening size to change from small (for concealment) to large (for waste disposal) and back again, resolving the contradiction between ease of operation and visibility.
3Stability of the object's composition
If the bag is made rigid to maintain structure, then stability is improved, but portability and foldability are reduced
Solution Approach 1:
The bag is constructed from flexible material that can be folded and compressed for portability yet maintains structural stability when in use. The flexible shell structure allows the bag to be collapsed into a compact form for carrying while providing sufficient rigidity to contain waste and maintain its shape during use, resolving the contradiction between structural stability and portability.

AI summary
A discrete food waste disposal bag is a hand held waste receptacle that will hold and conceal waste. A disposable bag comprising: a body having an open end portion and a sealed end portion, an air release flap located on the body between the open end portion and the sealed end portion, wherein the air release flap allows air to exit the body of the disposable bag, a first opening located at the end of the open end portion, wherein a user blows air into the first opening, a tear line located on the body approximate to the open end portion, wherein the tear line is configured to expose a second opening, wherein the first opening is smaller than the second opening.
