Modular Marking Aid for Door Assembly Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking aids for assembling components on building parts, such as finger protection devices on doors, are often complex and not suitable for confined spaces, leading to potential errors during assembly.
Innovation Solution
A marking aid with a base body and crossbars that provide stop surfaces for precise positioning, featuring feed-through openings for a marking tool, allowing for easy and accurate marking in tight spaces, and adaptable for use on both door frames and leaves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex marking aids are used to achieve precise positioning, then marking precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The marking aid is divided into a base body and a separate crossbar component. The crossbar can be attached to different positions on the base body depending on the marking location needed, segmenting the tool into modular parts that simplify the overall design while maintaining precision capabilities.
Solution Approach 2:
The base body is designed with multiple attachment positions for the crossbar, allowing the same marking aid to function for marking on different surfaces (door frame, door leaf, hinge side, counter-hinge side). This multi-functionality reduces the need for multiple specialized tools.
2Ease of operation
If traditional marking aids are used for door assembly, then marking capability is provided, but ease of operation in confined spaces deteriorates
Solution Approach 1:
The crossbar is designed to be detachably attachable to different positions on the base body, allowing the marking aid to dynamically adapt its configuration based on the specific marking location required. This dynamic reconfigurability enables easy operation in confined spaces while maintaining versatility.
Solution Approach 2:
The crossbar extends perpendicular to the base body, creating a T-shaped structure that allows marking on surfaces adjacent to the main facing direction. This dimensional extension enables marking on door edges and confined areas that would be inaccessible to conventional flat marking tools.
3Adaptability or versatility
If multiple specialized marking aids are used for different door components, then adaptability is improved, but device complexity and loss of time increase
Solution Approach 1:
The marking aid is designed as a universal tool with a base body that can accommodate crossbars for marking on door frames, door leaves, hinge sides, and counter-hinge sides. This single multi-functional tool replaces multiple specialized marking aids, eliminating tool selection and switching time.
Solution Approach 2:
The crossbar attachment positions are pre-designed and pre-positioned on the base body, allowing the user to quickly attach the appropriate crossbar for the specific marking task without complex setup or adjustment, reducing preparation time.

AI summary
A marking-out aid for application of an installation marking on an object, in particular on a building element, has a first stop surface (20) for the defined contact of the marking-out aid on the object, and also at least one first feedthrough opening (4) for receiving a marking tool (B). The marking-out aid has a basic body (1) and a first cross bar (2). The at least one first feedthrough opening (4) passes through the basic body (1). The first cross bar (2) is arranged at a first end of the basic body (1) and runs at a right angle to the basic body (1). The first cross bar (2) projects over the basic body (1) on at least one side, wherein that side of the first cross bar (2) which faces away from the basic body (1) forms the first stop surface (20). This marking-out aid is suitable in particular for the installation of finger protection roller screens and finger protection strip covers of doors.
