Color-Coded Surface Marking for Unevenness Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unevenness level inspecting devices primarily provide numerical data, lacking intuitive and visual representations of surface level discrepancies, which complicates site-level recognition and correction during construction.
Innovation Solution
An unevenness level inspecting device with a target, traveling unit, and a marker system that calculates and visually marks height differences on the surface using color-coded markings based on three-dimensional position coordinates, enabling intuitive recognition of level discrepancies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerical unevenness level information is provided, then measurement precision is improved, but ease of operation deteriorates due to complicated measurement and recognition processes
Solution Approach 1:
The patent applies color-coded markings to represent different levels of surface unevenness. The marker deposits colored marks on the surface, with different colors indicating different magnitude ranges of height differences. This transforms abstract numerical data into intuitive visual information, allowing workers to quickly recognize unevenness levels without complex measurements or data interpretation.
2Ease of operation
If color-coded markings are used to represent unevenness levels, then ease of operation is improved through intuitive visual recognition, but device complexity increases due to additional marker components
Solution Approach 1:
The patent combines the measurement function (surveying instrument) with the marking function (marker) into a single integrated device. The marker is positioned to work in conjunction with the surveying instrument, allowing the device to both measure surface unevenness and immediately mark the results with color-coded indicators. This merging eliminates the need for separate measurement and marking operations, reducing overall system complexity despite adding marking capabilities.

AI summary
Provided is a technology to enable printing of unevenness level information on a to-be-inspected surface in an intuitively and visually recognizable manner. An unevenness level inspecting device 1 includes a target T at a known distance from a to-be-inspected surface, a traveling unit 21 for traveling on the to-be-inspected surface, a first marker 23 for marking information on the to-be-inspected surface, and a control unit 10 configured to control the first marker 23, and the control unit 10 calculates a height of the to-be-inspected surface at a measurement position of the target T based on three-dimensional position coordinates of the target T input each time the unevenness level inspecting device 1 travels a predetermined distance, and controls the first marker 23 so as to mark unevenness level information indicating a difference between the height of the to-be-inspected surface and a reference height on a corresponding position on the to-be-inspected surface, and the unevenness level information is marked in a color that differs depending on a magnitude of the difference between the height of the to-be-inspected surface and the reference height.
