Brush Clip Structural Elements for Reduced Pressing Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush manufacturing processes require increased pressing forces and material input due to complex surface processing of clips, leading to higher production costs and potential component failure.
Innovation Solution
The brush design features structural elements on the clips that are disposed at a distance from the longitudinal edges, allowing for a continuous cutting edge and reduced pressing forces during production, thereby minimizing energy input and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If structural elements are formed by intersecting diagonal grooves on the clip surface, then anchoring strength is improved, but pressing forces increase and material input increases
Solution Approach 1:
The patent applies local quality by positioning structural elements only in specific zones of the clip - specifically in the projection areas that engage with the support material, while leaving the longitudinal edges free of such elements. This localized application maintains anchoring strength where needed while eliminating unnecessary material displacement at the edges, thereby reducing pressing forces and material input.
2Strength
If structural elements are formed by intersecting diagonal grooves on the clip surface, then anchoring strength is improved, but production costs increase
Solution Approach 1:
The patent reduces production costs by applying structural elements only locally in the projection areas rather than across the entire clip surface. This selective placement minimizes the complexity of surface processing required, reduces material consumption, and simplifies the manufacturing process while maintaining the necessary anchoring strength for functional performance.
3Strength
If structural elements extend into the longitudinal edges of the clip, then anchoring is improved, but pressing forces increase due to thickened portions
Solution Approach 1:
The patent extracts the structural elements from the longitudinal edges of the clip, positioning them only in the projection areas that require anchoring. By removing structural elements from the edge regions, the design eliminates the formation of thickened portions during pressing, thereby reducing pressing forces and preventing buckling without compromising anchoring strength in the functional areas.
4Reliability
If increased material input is used to prevent buckling during pressing, then component failure is reduced, but production costs increase
Solution Approach 1:
The patent prevents buckling and component failure by strategically positioning structural elements only in the projection areas where anchoring is needed, rather than uniformly across the entire clip. This localized reinforcement provides sufficient structural integrity during pressing without requiring increased overall material input, thereby maintaining reliability while reducing material consumption and production costs.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces production costs by minimizing energy input and material usage, while maintaining effective anchoring of bristle clusters, ensuring a durable connection with increased pulling forces.
Implementation Method 1
an anchoring is established between the structural elements formed on the clip projections and the material of the support as a result of the material displacement in conjunction with a flowing of the material caused by the material displacement when the clip projections are pressed into the material
