Solution Overview

Problem

Existing waste collection containers lack effective indicator elements for providing qualitative and quantitative information about the contents, especially in automated waste collection systems, leading to inefficiencies in handling and identification of waste fractions.

Innovation Solution

The integration of detachable indicator elements, including L-shaped reflector elements and colored indicators, on the waste collection containers, which provide visual cues for automated systems and allow for identification of waste fractions, even when lids are open or removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If indicator elements are attached to the lid device, then information can be provided about the container state, but the indicator elements become invisible or inaccessible when the lid is open or removed

Engineering Contradiction:
Improveinformation visibilityVSAvoidlid operation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The indicator element is divided into two separate parts: a first part attached to the container body and a second part attached to the lid device. These parts can be spatially separated when the lid is open, yet still function together to provide visible information about the container state (empty, partially filled, or full).

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The indicator element extends in multiple spatial dimensions with a first part positioned near the container body and a second part positioned near the lid device. This dimensional arrangement ensures that at least one part remains visible and accessible regardless of whether the lid is closed or open, solving the contradiction between information visibility and ease of operation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If the container body is made from recycled materials, then environmental sustainability is improved, but the visual appearance and color consistency may be compromised

Engineering Contradiction:
Improveuse of recycled materialsVSAvoidvisual appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The indicator element incorporates color-coded components (first part and second part can have different colors) that provide clear visual information about the container state. This compensates for any visual inconsistencies in the recycled container body material, allowing the indicator to convey precise information regardless of the container's appearance variations.

Inventive Principle:
Principle #32Color changes

3Productivity

If automated lift systems are used for waste collection, then collection efficiency is improved, but the systems require reliable visual indicators to function properly

Engineering Contradiction:
Improvecollection efficiencyVSAvoidsystem reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces complex mechanical sensing systems with simple optical/visual indicator elements that provide reliable information to automated lift systems. The color-coded, spatially distributed indicator parts allow automated systems to reliably determine container state (empty, partially filled, full) through visual detection, enhancing both productivity and reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention relates, inter alia, to a waste collection container (10), in particular a large waste collection container, having a container body (11) comprising a side wall, a container bottom (18) and an insertion opening, and comprising a lid device (24) for closing the insertion opening. Meanwhile, it has become common practice to provide waste collection containers (10) with different indicator elements by means of which different information regarding the waste collection container (10) is provided. According to the invention, the waste collection container has, among other things, an indicator system comprising different types of indicator elements (44, 50, 51, 52).
