Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control panels for machine tools require manual operations for inputting work instruction information, leading to complex and error-prone processes, and previous solutions like IC tags are prone to physical damage and complex system construction.
Innovation Solution
A control panel with an image pickup device for reading matrix type two-dimensional codes, which eliminates the need for manual input by processing and outputting read data directly from the codes printed on work instruction sheets, providing a more stable and secure management of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are used for inputting work instruction information, then the control panel can process information, but the operation becomes complicated and error-prone
Solution Approach 1:
The patent uses a two-dimensional code (optical copy) containing work instruction information instead of manual input. The code is read by an image pickup device, eliminating the need for operators to manually input data through keyboards or panels, thus simplifying operations while reducing errors.
Solution Approach 2:
The patent replaces the mechanical manual input system (keyboard, buttons) with an optical reading system. The image pickup device captures the two-dimensional code optically, and the control unit processes it automatically, substituting manual mechanical operations with automated optical-mechanical systems.
2Extent of automation
If IC tags are used to store work instruction information, then manual input is eliminated, but the system construction becomes complicated and the IC tag is prone to physical damage
Solution Approach 1:
The patent replaces the IC tag (electronic storage medium) with a two-dimensional code (optical pattern). The code can be printed on ordinary materials and read optically, eliminating the need for specialized electronic components while maintaining automation of information input.
Solution Approach 2:
The two-dimensional code can be printed on inexpensive, disposable materials such as paper or plastic sheets. Unlike IC tags that require specialized hardware and are prone to physical damage, the code can be easily reproduced and replaced if needed, reducing system complexity and cost.
3Reliability
If IC tags with antennas are used, then information can be stored electronically, but the antenna may fail and electromotive force cannot be obtained
Solution Approach 1:
The patent replaces the electronic IC tag with an optical two-dimensional code. The code consists of visual patterns that can be read by image pickup devices, eliminating the antenna and electromagnetic components that are prone to failure. The information is stored in the pattern itself rather than in electronic memory.
Solution Approach 2:
The patent substitutes the electromagnetic system (IC tag with antenna) with an optical system (two-dimensional code). The image pickup device uses optical sensors to read the code, replacing the radio frequency communication and electromagnetic power transfer, thus eliminating antenna failure risks.
