Cutting Aid for Insulation with Fold-Out Rulers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting aids for mineral wool insulation are complex, cumbersome, and difficult to use on-site, often resulting in inexact cuts and thermal bridges during roof insulation installation.
Innovation Solution
A cutting aid designed as a support strip with fold-out rulers and a cutting edge, featuring sliding tabs and stop plates for precise alignment and measurement, which can be easily transported and stored by folding into a compact form, and includes a magnet for securing the cutting blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a frame-like cutting aid with clamping elements and adjustable rulers is used, then cutting precision and adjustability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The cutting aid is divided into a base element and a separate support strip with rulers that can be positioned independently. The support strip is segmented into multiple support surfaces that can be individually adjusted along the rulers, allowing precise positioning without requiring a complex frame structure with multiple clamping elements.
Solution Approach 2:
The rulers and support surfaces are extracted from a fixed frame structure and made into separate, movable components. This allows the cutting aid to achieve adjustability and precision while reducing overall device complexity by eliminating the need for a rigid frame and multiple clamping mechanisms.
2Manufacturing precision
If a frame-like cutting aid with clamping elements is used, then cutting precision is improved, but ease of operation and portability deteriorate
Solution Approach 1:
The cutting aid is divided into a base element and a separate support strip with rulers that can be positioned independently. The support strip is segmented into multiple support surfaces that can be individually adjusted along the rulers, allowing precise positioning without requiring a complex frame structure with multiple clamping elements.
Solution Approach 2:
The support strip and support surfaces are designed to be dynamically adjustable rather than fixed. The support surfaces can be moved along the rulers and positioned at different locations, allowing the operator to easily adjust the cutting position while maintaining precision, without dealing with heavy clamping mechanisms.
3Manufacturing precision
If modular marking lines are provided on the insulation sheet, then cutting precision is improved, but adaptability to different cutting aids deteriorates
Solution Approach 1:
The support strip with rulers serves multiple functions: it provides measurement references aligned with the modular marking lines, supports the insulation sheet during cutting, and enables precise positioning of the cutting edge. This universal design works with different types of insulation sheets and marking systems without requiring specialized features.
Solution Approach 2:
The support strip acts as an intermediary between the modular marking lines on the insulation sheet and the cutting edge. It translates the marking line positions into precise cutting positions by providing rulers that align with the markings and supporting surfaces that stabilize the sheet during cutting, making the system adaptable to various marking configurations.

AI summary
The aid (1) has a support strip (2) with rulers (3a, 3b) pivoted from resting- and transport position into working position. The strip is tilted in the resting- and transport position and tilted out in the working position. An adjustable stop (5) is provided for bearing on a side area (6) or an edge of insulating elements. The stop is arranged as a movable tab (4) on the rulers and fixed in a desired position along longitudinal direction of the rulers. Distance of the stop to a cutting edge (34) of the strip corresponds to length of a to-be separated portion of the elements in the stop. The support strip is formed as an extruded section and made from light metal or plastic.
