Smart Load Diagram Display for Lifting Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting vehicles require operators to divert their attention from the operational field to read load diagrams, which can lead to maneuvering errors, especially when using traditional graphical or digital displays that are not aligned with the operator's vision.
Innovation Solution
A multifunctional lifting vehicle equipped with a smart display device, such as smart glasses, connected to an electronic control unit that processes stability data from sensors to provide a real-time load diagram directly in the operator's field of vision, allowing safe operation without the need to look away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional graphical or digital displays are used to show load diagrams, then the information can be displayed to the operator, but the operator must divert attention from the operational field leading to maneuvering errors
Solution Approach 1:
The patent transitions the display medium from traditional 2D screens (fixed in control cabs or on platforms) to 3D smart glasses that provide immersive, three-dimensional visualization of load diagrams directly in the operator's field of vision. This dimensional change allows the operator to view critical load information without diverting attention from the operational environment, thereby maintaining maneuvering safety while preventing information loss.
2Loss of information
If fixed screens are placed in the control cab or on the platform, then the load diagram can be displayed digitally, but the operator cannot view it and the operational field simultaneously
Solution Approach 1:
The patent introduces smart glasses as an intermediary device between the control system and the operator. These smart glasses act as a mediator that delivers load diagram information directly to the operator's visual field, eliminating the need for the operator to shift attention between fixed screens and the operational environment. This intermediary solution resolves the conflict between information visibility and ease of operation.
3Reliability
If smart glasses are used to display load diagrams, then the operator can maintain focus on the operational environment, but additional wearable equipment is required
Solution Approach 1:
The patent leverages the universal design of smart glasses, which are consumer electronic devices already equipped with display, processing, and wireless communication capabilities. By utilizing this multi-functional platform, the system avoids the need to design and manufacture specialized display equipment, thereby reducing overall device complexity while maintaining maneuvering safety through immersive load diagram visualization.
