Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Honeycomb plates made from synthetic polymers have sharp and brittle edges after cutting, which can lead to edge damage and contamination of cells with unwanted elements, and existing methods for edge protection are costly and limited to straight shapes.
Innovation Solution
A method involving making a first cut through a honeycomb sheet, filling the cut with a liquid filling material that solidifies, and then making a second cut through the filling material to separate the plate, allowing for edge protection and sealing of open cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cutting process is performed on a honeycomb plate made from synthetic polymers, then the plate can be separated into desired shapes, but the edges become sharp and brittle, leading to edge damage and cell contamination
Solution Approach 1:
The method applies a preliminary action by filling the cut with liquid polymer material immediately after cutting and before the plate is handled or used. This preliminary filling prevents the harmful effects of sharp edges and open cells before they can cause damage or contamination.
Solution Approach 2:
The liquid polymer material acts as an intermediary substance that fills the cut edges and cells. This intermediary material protects the vulnerable cut edges from damage and prevents contamination by unwanted elements entering the open cells.
2Reliability
If an extrusion process with a U-shaped tool is used to cover cut edges with protective film, then edge protection is achieved, but the tool becomes costly and complex
Solution Approach 1:
The method extracts the essential function of edge protection from the complex U-shaped extrusion tool. Instead of using a complex mechanical tool to apply protective film, the invention uses a simpler process of filling with liquid polymer that solidifies to provide protection.
Solution Approach 2:
The liquid polymer filling material serves as a simple, inexpensive alternative to costly protective films and complex extrusion tools. The filling material is applied directly and solidifies to provide permanent protection without requiring expensive equipment.
3Reliability
If protective film is applied to cut edges, then edge damage is prevented, but the method is limited to straight-shaped sockets only
Solution Approach 1:
The method changes the state of the filling material from liquid to solid, allowing it to adapt to any shape of the cut edge. The liquid polymer can flow into and fill any geometric configuration, then solidifies to provide protection, unlike rigid protective films that are limited to straight shapes.
Solution Approach 2:
The liquid polymer filling material provides universal protection for cut edges of any shape - straight, curved, or complex geometries. This single method replaces multiple shape-specific protective measures, making the process adaptable to various honeycomb plate configurations.

AI summary
The invention relates to a method for cutting a honeycomb panel. The honeycomb panel consists of a first sheet (4) held opposite and at a distance from a second sheet (6) by means of a honeycomb structure (8). The cutting method according to the invention involves the following steps: a) making a first cut (14) through the first sheet (4); b) filling the first cut (14) with a filler material (16) in a liquid state until the filler material is flush with the first sheet, the filler material being capable of subsequently solidifying; c) solidifying the filler material (16) filling the first cut (14); d) making a second cut (18) through the filler material, so as to allow separation of the panel along the first cut (14).
