Industrial Robot Control via Secure Touchscreen Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial robot control methods are expensive to manufacture and operationally susceptible, and require operators to constantly monitor touchscreens, making them insecure and difficult to use in adverse conditions.
Innovation Solution
A method using a secure monitoring device that allows industrial robots to be controlled via a graphic operator interface with virtual operating elements, where activation inputs are registered, coded, and confirmed, enabling secure initiation of functions without electrical components, relying solely on touch display operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manually operated devices with electrical components are used to control industrial robots, then the control functionality is comprehensive, but the device is expensive to manufacture and susceptible to operational failures
Solution Approach 1:
The patent extracts and removes all electrical operating elements (keys, switches, buttons) from the control device, retaining only the display component. This eliminates the complex electrical circuitry while maintaining control functionality through touch-based virtual operating elements displayed on the screen.
Solution Approach 2:
The patent replaces the mechanical/electrical operating elements with a touchscreen interface that detects touch positions and converts them into control signals. The mechanical key presses and switch operations are substituted with capacitive or resistive touch detection on the display surface.
2Ease of operation
If virtual operating elements on touchscreen are used, then the device is simpler and cheaper, but operators must constantly monitor the screen to avoid erroneous inputs
Solution Approach 1:
The patent enhances specific locations on the touchscreen by providing haptic feedback (tactile sensations) at the positions of virtual operating elements. This creates localized quality differences where touched areas provide tactile confirmation, allowing operators to locate and operate elements without visual monitoring while preventing erroneous inputs through tactile verification.
3Device complexity
If touchscreen operation is used in adverse environmental conditions, then the device can be simplified, but operation becomes difficult under strong light or darkness
Solution Approach 1:
The patent provides haptic feedback at the locations of virtual operating elements, creating tactile landmarks that remain detectable regardless of lighting conditions. This local quality enhancement through tactile sensations allows operators to locate and operate controls in darkness or under strong light without relying on visual display visibility.
