Remote Control Interface With Symbol-Based Pattern Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face difficulties in switching between different control patterns for remotely controlling machines, especially due to space constraints on the operator interface, which can lead to increased effort and confusion, and existing solutions do not efficiently manage multiple control patterns.
Innovation Solution
A remote control station with an operator interface that includes an indication system and a display device to show multiple control patterns, where each pattern is associated with a symbol, allowing operators to select and activate desired control patterns through an input signal, and a controller to transmit output signals for performing work operations based on the selected pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple face plates are used to illustrate different control patterns, then control pattern information can be displayed, but operator effort increases and face plate swapping is required
Solution Approach 1:
The patent uses graphical representations (symbols) on a single face plate to copy or represent multiple control patterns. Instead of requiring multiple physical face plates, the system creates visual copies of control pattern information through standardized symbols that can be displayed on one reusable face plate, eliminating the need for physical swapping while preserving all control pattern information.
2Ease of operation
If a single face plate is used for all control patterns, then face plate swapping is eliminated, but space constraints make it challenging to illustrate all control patterns
Solution Approach 1:
The patent segments control pattern information into discrete, standardized symbols that can be independently displayed on a single face plate. Each control pattern is broken down into essential graphical elements (symbols representing different machine functions and control directions) that can be arranged compactly on the limited face plate space, allowing multiple control patterns to be represented without requiring additional physical space.
Solution Approach 2:
The patent uses different symbols and their arrangements to represent different control patterns, analogous to using color changes to convey different information states. By varying the symbolic representation rather than requiring physical face plate changes, the system communicates multiple control patterns within the constraints of a single face plate's physical dimensions.
3Loss of information
If different control patterns are illustrated on the face plate, then control pattern information is available, but the face plate becomes complex and confusing
Solution Approach 1:
The patent applies local quality by using standardized, context-specific symbols in specific locations on the face plate. Each symbol has a defined meaning and position that corresponds to specific machine functions and control patterns. This localized, consistent symbolic language reduces overall face plate complexity by providing a predictable, organized structure rather than requiring elaborate illustrations for each control pattern.

AI summary
A remote control station includes an operator interface for remotely controlling at least one work operation. The operator interface includes at least one control device and an indication system having a first symbol associated with a plurality of control patterns of the at least one control device. The operator interface further includes a display device configured to display a plurality of control patterns thereon. Each of the plurality of control patterns includes a second symbol substantially similar to the first symbol. The remote control station also includes a controller configured to store the plurality of control patterns associated with the at least one control device. The controller is configured to receive an input signal from the operator interface for activation of one of the plurality of control patterns and transmit an output signal for performing the at least one work operation.
