Food Mould Ribs with Sharp Edges for Burr-Free Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moulds for food products fail to produce marks that give the required appearance, often resulting in burrs from welded ligaments that can tear packaging during handling.
Innovation Solution
A mould with intersecting ribs having sharp edges to create precise markings, and a modular assembly design with removable half-moulds to prevent packaging damage, using plastics materials for durability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If moulds with welded ligaments are used to produce marks on food products, then the marks can be formed on the product surface, but burrs are generated at the weld crossings that can tear the packaging
Solution Approach 1:
The mould is divided into separate ribs rather than continuous welded ligaments. Each rib is independent and has sharp edges without welds, eliminating burr generation while maintaining the marking function on food product surfaces
Solution Approach 2:
The sharp edges of the ribs, which could potentially be harmful, are controlled to create precise marks without generating burrs. The design converts the potential harm of sharp edges into beneficial precise marking while avoiding the harmful weld burrs through the segmentation principle
2Manufacturing precision
If traditional moulds with intersecting ligaments are used, then marks can be produced on food products, but the marks have wide grooves with cylindrical or flat profiles that do not give the required appearance
Solution Approach 1:
The ribs are designed with specific local geometry - sharp edges oriented towards the inside of the mould - to create precise mark profiles. This local quality control ensures the marks have the required appearance with defined groove profiles rather than generic cylindrical or flat shapes
Solution Approach 2:
Instead of having the ligaments intersect to create marks from the outside, the ribs are oriented with sharp edges pointing inward towards the food product. This inverted approach allows the ribs to imprint precise marks directly onto the product surface, creating the desired appearance
3Stability of the object's composition
If moulds with fixed half-moulds are used, then the mould structure is stable, but the mould parts cannot be easily replaced or customized
Solution Approach 1:
The mould is segmented into separate half-moulds that can be independently removed and replaced. This segmentation maintains structural stability during operation while enabling easy customization and replacement of individual half-moulds without affecting the entire mould structure
Solution Approach 2:
The mould transitions from a completely fixed structure to a dynamic system where half-moulds can be selectively attached and detached. This dynamic design allows the mould to maintain stability during use while enabling easy replacement and customization of individual components

AI summary
The invention concerns a mould for a food product, comprising at least one shell (302a, 302b) having a marking zone consisting of a plurality of ribs (402, 406) intersecting one another, said mould being characterized in that each rib (402, 406) has an edge (404, 408) having a sharp ridge oriented towards the inside of the mould in order to mark the food product during preparation thereof in said mould and in that said or each shell (302a, 302b) has, at the ends thereof, a recess (314, 414) intended to form, with the recesses (314, 414) of the other shells constituting the mould, a hollow (312, 412) that extends from the inside of the mould and in the direction of the outside of the mould.
