Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forklift trucks are limited to either manual operation requiring specific training or costly fully autonomous modes, which are restrictive and not adaptable to varying operational needs, especially in environments like factories.
Innovation Solution
A control system for forklift trucks that integrates human control members, environmental detection, navigation, and a switching module to enable multiple operating modes from fully autonomous to fully manual, including assisted modes, allowing for flexible operation and safety enhancements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a forklift truck operates in fully autonomous mode, then operational safety and productivity are improved, but the cost increases significantly and operational flexibility decreases
Solution Approach 1:
The system dynamically adjusts the level of automation based on operational needs, allowing the forklift to switch between fully manual mode, assisted manual mode, and fully autonomous mode. This dynamic adaptability resolves the contradiction by enabling high safety when automation is used while maintaining cost-effectiveness through selective rather than continuous automation deployment.
Solution Approach 2:
The control system integrates multiple operating modes within a single forklift platform, making the vehicle universally applicable to various operational requirements. The system can function as a manual forklift, an assisted forklift, or a fully autonomous vehicle, thereby resolving the cost contradiction by eliminating the need for separate specialized vehicles for different automation levels.
2Reliability
If a forklift truck operates in fully autonomous mode, then operational safety is improved, but operational flexibility and adaptability to varying needs deteriorate
Solution Approach 1:
The system employs dynamic mode switching that allows the operator to select between manual and autonomous operation based on real-time operational requirements. This resolves the adaptability contradiction by enabling the forklift to be manually controlled for complex or unpredictable tasks while utilizing autonomous mode for routine, safety-critical operations.
Solution Approach 2:
The control system segments the operating modes into distinct functional levels (manual, assisted manual, fully autonomous), allowing selective application of automation to specific tasks or operational contexts. This segmentation enables the system to maintain flexibility by applying autonomy only where appropriate while preserving manual control for tasks requiring human judgment.
3Extent of automation
If environmental detection and control modules are added to convert a manual forklift to autonomous mode, then automation capability is improved, but device complexity increases
Solution Approach 1:
The control system is designed as a universal platform that can operate at multiple automation levels using the same core hardware infrastructure. By sharing common sensors, processors, and actuators across manual and autonomous modes, the system reduces overall complexity compared to having separate systems for each mode.
Solution Approach 2:
The system incorporates self-diagnosis and selfconfiguration capabilities that automatically manage the complexity of the added modules. The control system can autonomously detect its own operational mode, activate appropriate subsystems, and manage sensor data processing, thereby reducing the operational burden and effective complexity for users.
4Adaptability or versatility
If multiple operating modes are implemented, then adaptability to varying operational needs is improved, but device complexity increases
Solution Approach 1:
The system uses dynamic mode switching with a unified control architecture that adapts its behavior based on the selected operating mode. Rather than implementing separate independent control systems for each mode, the system dynamically reconfigures the same hardware resources, thereby achieving high adaptability while minimizing the complexity increase through shared infrastructure.
