Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools for transferring the positions of measuring references from a construction frame to a surface lining are cumbersome, inaccurate, and time-consuming, especially for single-person use, and are not suitable for efficiently marking multiple outlets or cut-outs on a large scale.
Innovation Solution
A tool comprising a frame with a marking grid that allows for accurate alignment and transfer of reference positions from a construction frame to a surface lining, featuring adjustable legs, a magnetic net, or laser emitters to mark positions directly on the grid, which can then be transferred to the lining board without requiring multiple measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional measuring tools (T-square, slider, arms) are used to transfer positions, then measurement can be performed, but the device becomes very cumbersome and difficult for one person to use
Solution Approach 1:
The tool is divided into two main separable parts: a frame part that remains on the construction frame and a board part that attaches to the surface lining. This segmentation allows each part to be optimized independently and makes the tool easier to handle and transport while maintaining measurement precision through the connection elements (laser emitters, magnetic nets, or mechanical linkages).
Solution Approach 2:
The patent introduces intermediary elements such as laser emitters, magnetic nets, or rigid connection mechanisms that mediate between the construction frame and the surface lining. These intermediaries enable accurate position transfer without requiring the user to manually measure and mark positions, thus improving ease of operation while maintaining precision.
2Measurement precision
If multiple T-squares or arms are used to measure in different directions, then complete position measurement is achieved, but the apparatus becomes very cumbersome and time-consuming
Solution Approach 1:
The patent merges multiple measurement functions into a single integrated tool. The frame part and board part together provide both horizontal and vertical position transfer capabilities simultaneously, eliminating the need to use multiple separate T-squares or arms. This reduces the time required for measurement while maintaining complete position measurement accuracy.
Solution Approach 2:
The tool is designed to perform multiple functions: transferring positions in both horizontal and vertical directions, marking multiple outlets or cut-outs, and providing reference lines. This multi-functionality is achieved through the combination of frame and board parts with various marking mechanisms, reducing the need for multiple specialized tools and saving time.
3Productivity
If traditional measurement methods are used, then positions can be transferred, but errors occur and measurements must be repeated
Solution Approach 1:
The patent incorporates feedback mechanisms such as laser emitters that project reference lines and magnetic nets that provide visual feedback for alignment. These feedback mechanisms allow the user to verify correct positioning in real-time, reducing errors and the need for repeated measurements, thus improving both reliability and productivity.
Solution Approach 2:
The patent replaces traditional mechanical measurement systems (rulers, T-squares, manual marking) with optical and magnetic systems (laser emitters, magnetic nets). This substitution eliminates many sources of human error associated with manual measurement and marking, significantly improving the reliability and efficiency of position transfer.
4Productivity
If a large frame is used to cover the entire wall area, then all positions can be marked at once, but the frame becomes difficult to transport between construction sites
Solution Approach 1:
The tool is segmented into a smaller frame part and a board part that can be separately transported. This segmentation reduces the weight and size of each component, making them easier to carry between construction sites, while still enabling the marking of multiple positions simultaneously through the coordinated use of both parts.
Solution Approach 2:
The board part can be nested within or attached to the frame part when not in use, and vice versa. This nesting arrangement minimizes the overall size and weight of the tool during transport, while allowing both components to be deployed together for efficient multi-position marking at the construction site.
