Remote Control Button Sequence Testing for Materials Handling Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for remote control devices associated with materials handling vehicles lack an efficient method for testing operational characteristics and ensuring proper functionality, particularly in terms of button pressing sequences and timing, which can lead to operational errors and inefficiencies.
Innovation Solution
A method and system that involve a processor waiting for specific button inputs from a remote control device, determining the success of a predetermined button pressing sequence, and providing a visual indication on the vehicle, while also considering the connection to a charging station and timing constraints, to ensure proper operation of vehicle functions like horn, brake, or fork operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a remote control device is used to control materials handling vehicle functions, then operator safety and control precision are improved, but the complexity of testing and validating button pressing sequences increases
Solution Approach 1:
The system performs self-testing by automatically detecting button pressing sequences and providing visual feedback without requiring external testing equipment. The processor monitors inputs from the remote control device and drives displays to indicate successful or unsuccessful sequences, enabling the system to validate its own operational characteristics.
Solution Approach 2:
The system provides immediate visual feedback through displays on the materials handling vehicle indicating whether button pressing sequences were successful or unsuccessful. This feedback mechanism allows operators to learn correct sequences and ensures proper device functionality without complex external testing apparatus.
2Measurement precision
If multiple button pressing sequences are implemented for vehicle functions, then operational precision and safety are improved, but the time required for operator training and validation increases
Solution Approach 1:
The system pre-programs multiple button pressing sequences for different vehicle functions (travel, horn, brake, fork operation) and automatically detects them during operation. This preliminary setup eliminates the need for time-consuming manual testing and validation of each sequence, as the system is already configured to recognize and validate the correct sequences.
Solution Approach 2:
Immediate visual feedback is provided to operators indicating whether their button pressing sequences were successful or unsuccessful. This real-time feedback accelerates the learning process and reduces the time required for operator training and validation of multiple sequences.
3Reliability
If timing constraints are enforced for button pressing sequences, then operational reliability is improved, but the difficulty of detecting and measuring sequence correctness increases
Solution Approach 1:
The system automatically monitors the timing of button presses and provides visual feedback indicating whether sequences were executed within required time constraints. This automated timing detection and feedback mechanism simplifies the measurement process while ensuring reliable sequence execution.
Solution Approach 2:
The system replaces manual timing measurement and validation with automated electronic detection through the processor. The processor automatically tracks button press timestamps and determines whether sequences meet timing requirements, eliminating the need for complex manual timing measurement procedures.

AI summary
Testing operational characteristics of a remote control device associated with a materials handling vehicle can include waiting for receipt of a first input indicative that a first button of the remote control device has been pressed, wherein the first button comprises a travel button of the remote control device. The testing may further comprise waiting for receipt, subsequent to receiving the first input, of a second input indicative that at least a second button of the remote control device has been pressed, wherein the second button relates to a first auxiliary vehicle function. The testing still further comprises determining whether or not a predetermined button pressing sequence is successful based at least in part on receiving or not receiving the first and second inputs; and optionally driving a display on the vehicle to provide a visual indication that the button pressing sequence is successful or not successful based on the determination.
