Waste Container Insertion Lid Structure for Odor Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste containers allow odors to diffuse outside when the lid is opened for waste disposal, as the deodorizing mechanism requires the lid to be fully opened, exposing the interior and causing odor dispersion.
Innovation Solution
A waste container with a closing body featuring a hollow structure and an opening and closing member that advances and retracts along a guide path to stabilize air movement, using an airtight material to separate the interior from the exterior and incorporating a deodorizing portion for efficient odor removal.

Engineering Contradiction Analysis
1Object-generated harmful factors
If the upper lid is opened widely to spray deodorizer, then the deodorizing function is improved, but odor diffusion to the outside increases
Solution Approach 1:
The upper lid is divided into a main lid body and a separate insertion lid. The insertion lid can be opened independently to provide access for waste disposal, while the main lid body remains closed to contain odors. This segmentation allows deodorizing functionality without requiring full lid opening.
Solution Approach 2:
The insertion lid is designed with specific local properties - it is smaller and can be opened independently from the main lid body. This local opening capability provides targeted access for waste disposal while maintaining odor containment in the main container, addressing the contradiction between accessibility and odor prevention.
2Ease of operation
If the insertion opening is opened for waste disposal, then waste can be discarded, but odors inside the main body diffuse to the outside
Solution Approach 1:
The lid system is segmented into two independent parts: the main lid body and the insertion lid. The insertion lid can be opened independently for waste disposal without opening the main lid body, thus maintaining odor containment while providing operational access.
Solution Approach 2:
The insertion lid is designed to be opened first before the main lid body. This preliminary action allows waste disposal to be completed through the smaller insertion opening, after which both lids can be closed to seal odors inside, preventing diffusion to the outside.
3Ease of operation
If the opening and closing member moves freely to open the insertion opening, then the opening operation is simple, but air disturbance causes odor diffusion
Solution Approach 1:
The guide portion is pre-formed in the closing body to define the movement path of the opening and closing member. This preliminary structural arrangement ensures that when the insertion opening is opened and closed, the member follows a controlled path that minimizes air disturbance and odor diffusion.
Solution Approach 2:
The guide portion acts as an intermediary structure between the opening and closing member and the air inside the insertion portion. It mediates the movement of the opening and closing member, constraining it to a specific path that reduces air turbulence and prevents odor escape.

AI summary
[Problem] To prevent diffusion of odors to the outside from an insertion opening that is opened when waste is discarded. [Solution] A trash bin A consists of a container body 1, which has a substantially rectangular parallelepiped shape and an open upper portion, and a closing body 2, which is fitted and attached to the container body 1. An opening 10 is provided in the upper portion of the container body 1, and the closing body 2 is attached so as to substantially close the opening 10 of the container body 1. The closing body 2 has an insertion portion 21 in which an insertion opening 22 is formed, and opening and closing members 233 that open and close the insertion opening 22 are configured to be capable of being housed in insertion members 21a and 21b.
