Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing the base from linoleum-covered surfaces are either damaging, time-consuming, or result in aesthetically unappealing irregularities, leading to costly and inefficient processes.
Innovation Solution
A method involving an apparatus where linoleum is conveyed on a working surface with a cutting edge that separates the linoleum from its base, using drive and retainer rollers to ensure even removal and prevent scratches, allowing for continuous movement and precise positioning to achieve a smooth finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the base is removed by softening in water, then the base becomes easier to tear or rub off, but this causes damage at the front side of the edge band and leaves irregularities with base residue at the back side
Solution Approach 1:
The patent replaces the mechanical/chemical softening process with a thermal cutting process. A cutting edge heated to a specific temperature range (200-400°C) is used to separate the linoleum from the base through controlled thermal interaction, eliminating the need for water softening and subsequent mechanical removal that causes surface damage and irregularities.
Solution Approach 2:
The patent changes the physical state and properties of the cutting edge by controlling its temperature within a specific range (200-400°C). This temperature parameter allows the cutting edge to effectively separate the linoleum from the base without causing damage to the linoleum surface or leaving residue on the base, thereby improving both ease of manufacture and manufacturing precision.
2Ease of manufacture
If the base is removed by grinding with sandpaper or smoothing machine, then the base can be removed, but this causes scratches at the front side of the linoleum band and is time and manpower demanding
Solution Approach 1:
The patent replaces the mechanical grinding system with a thermal separation system. Instead of using abrasive sandpaper or smoothing machines that physically scrape and scratch the linoleum surface, a heated cutting edge is used to thermally separate the linoleum from the base, eliminating scratches and surface damage while improving manufacturing efficiency.
Solution Approach 2:
The heated cutting edge acts as an intermediary between the linoleum-base composite and the removal process. By introducing thermal energy through the cutting edge, the separation process is facilitated without direct mechanical contact that would cause scratching, thereby improving both ease of manufacture and surface quality.
3Ease of manufacture
If the linoleum band is fixed during grinding process, then grinding can be performed, but the linoleum band is easily displaced despite attempts to fix it
Solution Approach 1:
The patent replaces the mechanical fixing and grinding system with a thermal separation system. The heated cutting edge is pressed against the moving linoleum band, and the thermal interaction enables clean separation without requiring mechanical fixation. This eliminates the displacement problem inherent in mechanical grinding while maintaining process feasibility.
Solution Approach 2:
The patent introduces dynamic movement to the process by allowing the linoleum band to move continuously through the cutting edge. Rather than attempting to fix the linoleum in a static position during processing, the system accommodates movement, ensuring consistent thermal separation while eliminating positioning and displacement issues.
4Ease of manufacture
If water softening method is used to remove base, then base becomes easier to remove, but the process is demanding time and manpower and therefore cost-heavy
Solution Approach 1:
The patent replaces the time-consuming water softening and mechanical removal process with a rapid thermal cutting process. The heated cutting edge separates the linoleum from the base in a single continuous action, eliminating the multi-step softening and removal process, thereby dramatically improving production efficiency while maintaining ease of base removal.
Solution Approach 2:
The patent implements continuous useful action by allowing the linoleum band to move continuously through the heated cutting edge during the separation process. This eliminates the intermittent stopping and starting required in water softening methods, maintaining continuous productive action and significantly improving overall production efficiency.

AI summary
The invention concerns a method where linoleum with a base is introduced in an apparatus, where the linoleum is conveyed on a working surface, where the linoleum is advanced by means adapted therefore against a cutting edge, wherein the cutting edge is arranged such that linoleum while moving in the apparatus is separated from the base. By this method is achieved an even back side on the linoleum band, making the band suited for further processing since no irregularities appear on the back side where the base is removed, and the front side is without any damages and scratches from the process. Linoleum band having removed the base according to this method contributes to a good finish at the produced linoleum covered edge, since the even back side propagates to the front side on the linoleum covered plate edge which then appears even and with good aesthetic effect, making it attractive. The invention furthermore includes the product appearing by the method and the use of this product.
