Waste Container Collar Blocking Element for Safe Comb Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy waste containers pose safety risks and risk damage when emptied using comb lifting devices, as they can become overloaded and jam, necessitating the use of trunnion lifting devices for safer load distribution, but comb devices are often preferred for speed and ease, despite safety concerns.
Innovation Solution
A waste container with a blocking element that prevents the comb lifting device's teeth from entering the container collar, allowing the comb lifting device to be used safely even with heavy loads by blocking the receiving space, thus ensuring secure locking and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a comb lifting device is used to empty heavy waste containers, then the emptying process is faster and easier, but safety risks increase and damage may occur due to overload and jamming
Solution Approach 1:
The blocking element is designed to be detachably mounted, allowing the system to dynamically switch between blocked (safe) and unblocked (efficient) states based on container weight conditions. This dynamic configuration enables the comb lifting device to adapt its functionality from potential jamming risk to safe operation.
Solution Approach 2:
The blocking element acts as an intermediary component between the container collar and the comb lifting device teeth. It mediates the interaction by selectively preventing tooth entry into the receiving space, thereby controlling whether the lifting device can engage with the container and preventing unsafe jamming conditions.
2Reliability
If the comb lifting device teeth enter the container collar receiving space, then secure locking is achieved, but jamming and overload damage occur with heavy containers
Solution Approach 1:
The blocking element applies preliminary anti-action by preventing the comb lifting device teeth from entering the container collar receiving space when the container is heavily loaded. This pre-emptive blocking action avoids the harmful jamming and overload damage before they can occur during the lifting process.
3Reliability
If a blocking element is added to prevent tooth entry, then safety is improved, but device complexity increases
Solution Approach 1:
The blocking element is designed as a separate, detachable component rather than an integrated permanent feature. This segmentation allows the safety function to be added independently to existing containers, minimizing the increase in overall system complexity while maintaining the ability to block tooth entry when needed.

AI summary
The present invention relates to a waste container (10), said waste container (10) comprising a waste container body (11) having a container bottom (12), a container top rim (15) which encompasses a container opening and a container side wall (13; 13a, 13b, 13c) extending between the container bottom (12) and the container top rim (15), wherein the container top rim (15) comprises a container collar (20) or wherein the container top rim (15) is provided as a container collar (20), said container collar (20) protruding outwardly from the container side wall (13; 13a), wherein the container collar (20) is open pointing towards the container bottom (12), and wherein the container collar (12) provides a receiving space (21), which is adapted for interacting with a lifting device of a refuse collecting entity. Very heavy waste containers (10) cannot get emptied with a comb lifting device. For safety reasons, collection companies often instruct their operatives to empty heavy waste containers (10) via the trunnion lifting device. Practically, it is however often much more appropriate to keep using the comb lifting device. In order to make this possible, the waste container (30) comprises at least one blocking element (30), which is adapted for blocking the lifting device from entering the receiving space (21), wherein the blocking element (30) is configured as a polygonal body, wherein the blocking element (30) is at least partially disposed inside the receiving space (21) or can get at least partially disposed inside the receiving space (21), and wherein the blocking element (20) is or can get, preferably detachably, mounted to the container side wall (13; 13a) and/or to the container collar (20).
