Measuring Rod with Movable Scale for Laser Leveling Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser leveling system measuring rods do not efficiently allow direct recognition of height differences between a point on an existing surface and a horizontal surface to be set up at a defined height above it, particularly in modular floor support assembly, requiring complex calculations and readability adjustments.
Innovation Solution
A measuring rod design featuring a longitudinally movable outer part enclosing the inner part, with a marking and length scale on one part visible relative to the other, allowing the marking to be displaced and fixed at selectable positions, enabling direct reading of height differences without additional calculations by aligning the rod vertically and moving parts to match the laser beam's target marking with the zero point of the length scale.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the length scale is attached to the outer longitudinal section for better readability, then the reading convenience is improved, but the ability to directly indicate height differences for modular floor support assembly is reduced
Solution Approach 1:
The measuring rod is pre-configured with a zero mark on the inner longitudinal section and a length scale on the outer longitudinal section. By moving the outer section relative to the inner section, the system preliminarily calculates the height difference and presents it directly as a readable value, eliminating the need for post-measurement calculations.
Solution Approach 2:
The outer longitudinal section acts as an intermediary between the laser beam detection and the final height difference measurement. It carries the length scale and can be moved relative to the inner section to directly indicate the height difference, serving as a mechanical calculator that translates raw measurements into useful information.
2Measurement precision
If the measuring rod requires complex calculations to determine height differences, then measurement precision can be maintained, but productivity and assembly speed are reduced
Solution Approach 1:
The measuring rod performs self-calibration and self-calculation through the movable outer longitudinal section. The system automatically determines the height difference by the position of the outer section relative to the inner section, without requiring the user to perform calculations, thus maintaining precision while improving productivity.
3Device complexity
If the marking is fixed on the inner longitudinal section, then the structural simplicity is maintained, but the adaptability to different measurement scenarios is reduced
Solution Approach 1:
The outer longitudinal section is made movable relative to the inner longitudinal section, transforming the measuring rod from a static to a dynamic system. This allows the zero mark and length scale to be repositioned according to different measurement scenarios, such as adjusting for different floor support module heights, while maintaining structural simplicity through a straightforward sliding mechanism.

AI summary
The invention relates to a measuring rod for use in a laser leveling system, wherein the measuring rod has an inner longitudinal part (1) and an outer longitudinal part (2) that is longitudinally displaceable therefrom, wherein a marking (3) is attached to one of the longitudinal parts (1, 2) and a length scale (4) extends along the longitudinal direction of the other of the longitudinal parts (2, 1), wherein the marking (3) on one longitudinal part (1, 2) is displaceable in the longitudinal direction of this longitudinal part and can be detachably fixed at selectable positions, and/or the length scale (4) on the other longitudinal part (2, 1) is displaceable in the longitudinal direction of this other longitudinal part (2, 1) and can be detachably fixed at selectable positions. Parallel to the length scale (4) runs a support element scale (14), on which the length units shown correspond to the effective lengths of modules (15, 16, 17) of a foot support that can be assembled from several of these modules.
