Industrial Truck Display Dynamic Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial truck displays overwhelm users with multiple types of information, making it difficult to quickly identify relevant data during operation, leading to potential safety hazards and inefficiencies.
Innovation Solution
An industrial truck with a controller that dynamically adjusts the display area of control information based on the truck's operational status, prioritizing material handling or movement information to ensure the user focuses on the most critical data without needing multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple types of control information are displayed simultaneously on the display, then the display provides comprehensive information about truck operation, but the user cannot quickly identify relevant information under current circumstances
Solution Approach 1:
The display dynamically adjusts the display area of different control information based on the current operational status of the industrial truck. The controller determines which information is most relevant at any given moment and allocates display space accordingly, making the display adaptive rather than static. This resolves the contradiction by maintaining comprehensive information availability while enabling quick identification of relevant data through dynamic reconfiguration.
Solution Approach 2:
Different regions of the display are allocated different qualities or priorities based on operational context. When material handling is the current operation, material handling information receives enhanced display area and prominence. This local quality differentiation allows the user to quickly identify relevant information without being overwhelmed by all available data, resolving the contradiction between comprehensive information and ease of identification.
2Loss of information
If all control information is displayed with equal visibility, then no information is hidden, but the user spends excessive time reading the display and attention is distracted from operation
Solution Approach 1:
The display system dynamically reconfigures information presentation based on operational status, adjusting which information is most visible at any moment. This dynamic adaptation ensures that all information remains potentially visible while minimizing the time needed to find relevant data, as the display proactively highlights context-relevant information rather than requiring the user to search through static equal-weighted data.
Solution Approach 2:
The system extracts and prioritizes the most relevant information based on current operational context, presenting it with enhanced visibility while maintaining access to other information. This extraction of critical information from the full data set reduces the time users need to spend reading the display while ensuring no important information is completely hidden, resolving the contradiction between full visibility and time efficiency.
3Ease of operation
If a larger display or multiple displays are used to show all information clearly, then information readability improves, but the device complexity and size increase
Solution Approach 1:
A single display dynamically adapts its content presentation based on operational status, eliminating the need for multiple displays or a larger display system. By reconfiguring which information receives prominent display space according to context, the system achieves high readability without increasing hardware complexity, resolving the contradiction between readability and device complexity.
Solution Approach 2:
The single display performs multiple functions by dynamically adjusting its content prioritization based on operational context. It serves as both a comprehensive information source and a focused attention guide depending on the situation, replacing what would otherwise require multiple specialized displays. This multi-functionality achieves high readability while maintaining simple device architecture.
