Waste Container Transparent Casing Media Surface Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste collection containers with media surfaces on the outer sack face difficulties in sack replacement, requiring the sack to be removed through the bottom and necessitating a hung model, which complicates the process and damages the sack, and also presents challenges in print techniques and durability.
Innovation Solution
A waste container with a transparent, curved casing that can be steered to a steeper curvature for media surface changes, allowing side edges to detach and using guide surfaces for easy poster media insertion, enabling sack replacement without emptying and protecting the sack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the outer surface of the refuse sack functions as the media surface, then the container can be simplified to a hung model, but the sack becomes damaged easily and the changing process becomes difficult
Solution Approach 1:
The patent separates the media surface function from the refuse sack by introducing a dedicated transparent casing (6) that serves as the outermost part of the container. The sack is segmented into an internal waste-containing component, while the casing provides the external media surface. This allows the sack to be changed without removing it through the bottom, eliminating damage to the sack during replacement.
2Device complexity
If the outer surface of the sack functions as the media surface, then the container structure is simplified, but the sack must be removed through the bottom requiring a hung model
Solution Approach 1:
By separating the media surface function from the sack and assigning it to a dedicated transparent casing, the sack can be accessed and changed from the front opening without requiring removal through the bottom. The casing remains in place as the outermost structure, while the sack is independently replaceable.
3Device complexity
If the outer surface of the sack functions as the media surface, then the container is simplified, but the media surface shape deviates from ordinary shape causing print technique challenges
Solution Approach 1:
The transparent casing (6) is designed with a specific curved shape optimized for media surface display, while the sack maintains its functional shape for waste containment. The casing acts as an interface that provides a standardized, print-friendly surface geometry, separating the display requirements from the containment requirements.
4Productivity
If the transparent casing is made steeper for media surface changes, then the changing speed is improved, but the casing must be detached from the curved surface requiring slot places
Solution Approach 1:
The casing is pre-formed with a steeper curvature that facilitates rapid media surface changes. The slot places are pre-positioned at the edges of the curved surface, allowing the casing to be quickly detached and reattached without requiring complex real-time adjustments during the changing process.

AI summary
Waste container that is formed of a base part (1), a container body attached on top of it which container body comprises an outer casing (6) and a cover plate (7) attached to the upper surface of the container body in which case the cover plate comprises a gap (5) for locating the waste into the container and the container body (6), (7) comprises at least one curved surface (6) that makes the mentioned body to have a shape of a vertical cylinder which surface is meant to be a media surface for example for commercials (8) and that a transparent casing (2) is located outside the mentioned surface (6) in which case the film (8) that functions as the media surface is located between (2) the curved surface (6) and the casing. A transparent, curved casing (2) can be brought to be more curved for the changing of the media surface (8) in which case out of the length of the both side edges of the casing (2) at least a part comes out of the slot places (4) formed at the edges of the curved surface (6) so that the casing (2) can diverge from the curved surface (6).
