Digital Panel for Belt Sander Displacement Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional belt sanders have limited displacement distance measurement precision due to small scale intervals, making it difficult for users to accurately read and interpret the displacement of the workbench relative to the chassis, leading to potential measurement errors and reduced processing quality.
Innovation Solution
A digital panel is integrated into the belt sander, comprising a control module, detection module, and digital display module, which includes motor drive and speed detection components, allowing for precise monitoring and display of conveyer and abrasive belt wheel motor states, including position and rotation speed, enhancing user convenience and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a dial indicator with scales is used to measure workbench displacement, then the measurement function is provided, but the measurement precision is insufficient due to small scale intervals that are difficult to read
Solution Approach 1:
The patent replaces the mechanical dial indicator system with a digital detection and display system. Sensors detect the actual displacement values and transmit them to a digital display module, which shows the measurements in numerical form. This substitution eliminates the need for users to read small scale intervals visually, thereby improving both measurement precision and reading ease.
Solution Approach 2:
The patent introduces a digital display module as an intermediary between the measurement mechanism and the user. Instead of directly observing the dial indicator scales, users view the processed numerical data on the digital display. This intermediary transforms the physical displacement into easily readable digital information, resolving the contradiction between precision and readability.
2Length of moving object
If the workbench displacement distance is limited, then the measurement range is constrained, but the scale interval becomes too small for clear reading
Solution Approach 1:
The patent replaces the mechanical scale-based measurement system with an electronic sensing and digital display system. The detection module accurately measures the displacement regardless of the total range, and the digital display presents the precise numerical value. This allows for accurate measurement even over limited displacement distances, as the system does not rely on physical scale intervals.
3Loss of information
If a digital panel is added to the belt sander, then the operation information and running state are displayed clearly, but the device complexity increases
Solution Approach 1:
The digital panel is designed to perform multiple functions: displaying operation information, showing running state, and providing clear numerical data. By consolidating these functions into a single integrated panel, the system reduces information loss without proportionally increasing complexity. The panel serves as a multi-functional interface that addresses multiple information display needs simultaneously.

AI summary
A digital panel of a belt sander includes a control module. The control module is electrically connected with a conveyer motor and an abrasive belt wheel motor of the belt sander. The control module is connected with a detection module. The control module is further connected with a digital display module and an operation module. Thereby, the operation module controls the conveyer motor and the abrasive belt wheel motor of the belt sander, and detects the running state of the conveyer motor and the abrasive belt wheel motor through the detection module, and displays the running data of the conveyer motor and the abrasive belt wheel motor through the digital display module for the belt sander to be digitalized.
