Forklift Display Interface for Automated Operating Zone Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial truck systems require time-consuming and tedious manual settings for operating zones, and automated solutions like RFID transponders are costly.
Innovation Solution
An industrial truck with a display and operating device that allows for one-time selection of an operating zone using a switching element, automatically applying fixed function settings, which can be changed only if permitted, and retains previous settings upon returning to that zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of function settings is used when moving between operating zones, then the system remains simple and cost-effective, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system pre-defines multiple operating zones with pre-configured function settings stored in memory. When the operator selects an operating zone using the display and control device, the corresponding settings are automatically applied without manual adjustment of each individual function, thus reducing adjustment time while maintaining system simplicity
Solution Approach 2:
The display and control device creates a digital representation of operating zones with their associated function settings. The selected operating zone's settings are copied and applied to the control system, eliminating the need for manual reconfiguration of each setting while keeping the hardware simple
2Extent of automation
If automated adaptation using RFID transponders is implemented, then function settings are automatically applied when entering operating zones, but the system becomes expensive due to localization infrastructure requirements
Solution Approach 1:
The operator themselves performs the selection of the operating zone through the display and control device interface. This self-service approach eliminates the need for expensive automated localization infrastructure like RFID transponders, while still achieving automatic application of function settings through the digital selection mechanism
Solution Approach 2:
The display and control device serves as an intermediary between the operator and the control system. It provides a menu interface for selecting operating zones and automatically translates this selection into the appropriate function settings, achieving automation without requiring expensive physical localization infrastructure
3Adaptability or versatility
If multiple function settings are adjusted individually, then precise control over each function is maintained, but the overall process becomes cumbersome and complex
Solution Approach 1:
The system merges multiple individual function settings into pre-configured operating zone profiles. When an operator selects an operating zone, all associated functions are adjusted simultaneously as a group rather than individually, reducing the perceived complexity while maintaining the ability to control each function through the unified interface
