Scraper Grid Segmented Retaining Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Containers with scraper grids are prone to damage during transport and handling due to lateral forces and tilting, leading to instability and potential detachment, especially when stacked, which compromises the usability and protection of the grid.
Innovation Solution
The scraper grid is designed with additional separable connections between the holding projections and the grid body, providing extra stability and fixing the projections in position, both in transport and working positions, to prevent deformation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the scraper grid is attached to the container lid during transport, then the grid is protected and positioned correctly, but the grid is vulnerable to damage from lateral forces and tilting when containers are stacked
Solution Approach 1:
The retaining projection is divided into multiple segments connected by hinge connections, allowing each segment to independently absorb and distribute mechanical stresses from lateral forces and tilting during transport and stacking, preventing damage to the entire grid structure
Solution Approach 2:
The retaining projection transitions from a rigid structure to a flexible articulated structure through hinge connections, changing its mechanical parameters to accommodate lateral forces and tilting while maintaining attachment reliability during transport
2Ease of operation
If the retaining projection is located at the edge of the grid for easy attachment, then the grid can be easily mounted on the container, but the projection is more easily damaged or deformed due to exposure and adjacent recesses
Solution Approach 1:
The retaining projection is segmented into multiple connected parts with hinge joints, distributing the mechanical stress across multiple points rather than concentrating it at a single vulnerable edge location, thereby maintaining integrity while preserving ease of attachment
3Ease of operation
If the scraper grid is made detachable for easy separation during handling, then the grid can be easily removed and repositioned, but the grid can easily be damaged or unintentionally detached during transport of stacked containers
Solution Approach 1:
The attachment system transitions from a static rigid connection to a dynamic articulated connection with hinge joints, allowing the retaining projection to adapt to lateral forces and tilting during transport while maintaining stable attachment, yet still permitting easy intentional detachment when needed

AI summary
The invention relates to a container (1) for coating compositions with a container opening (4) for removing the coating composition, a circumferential side wall (5) and a lid (20) that can be fixed to this side wall, and with a scraper grid (30) having a body (31) that is at least substantially flat and having a central scraper surface (32), wherein the scraper grid can be detachably attached to the container or lid in a first transport position and wherein the scraper grid can be positioned in a second working position with the container open in an arrangement mounted on the side wall of the container, wherein the scraper grid has at least one or more receptacles (34) opening into the circumferential edge (33) of the same for the side wall of the container when the grid is mounted on the side wall of the container.wherein the receptacle has a retaining projection (35) laterally limiting it towards the scraper surface and the retaining projection is arranged outside the container when the grid is attached. According to the invention, the at least one or more retaining projections each have at least one connection (36) to the body of the scraper grid at the level of the receptacle, wherein the connection is designed to be cutable, thereby continuously fixing the respective retaining projection to the scraper grid.
