Construction Equipment Display Indicators for In-View Risk Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction equipment operators often fail to recognize work errors or risk signals due to displays being located away from their primary focus, leading to potential accidents.
Innovation Solution
A display system with indicators installed within the operator's field of view, using light-emitting units to visually display work information such as work depth, height, POD, lifting weight, and battery charging status in different colors based on deviation from preset criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display is located on the side of the cabin, then the work range information can be displayed, but the operator cannot easily recognize it when focusing on the front work device
Solution Approach 1:
The patent extracts the critical work range information from the main display and presents it separately through indicators positioned in the operator's direct field of view. This separation allows the operator to monitor work range compliance without diverting attention from the primary work area, effectively resolving the contradiction between information visibility and operational focus.
Solution Approach 2:
The patent transitions the display of work range information from a two-dimensional screen interface to a spatial arrangement of indicators positioned at multiple locations around the operator's field of view. This dimensional change ensures that critical information is always within the operator's natural line of sight, eliminating the need to shift attention between the display and work area.
2Reliability
If the operator focuses on the work field, then the primary work can be monitored, but risk signals are recognized late leading to potential accidents
Solution Approach 1:
The patent applies local quality by positioning different types of indicators (work range indicators and risk signal indicators) at specific locations within the operator's field of view. Critical safety information is placed in prominent positions that ensure immediate visibility, allowing the operator to recognize risk signals instantly without diverting attention from the work field, thereby preventing accidents while maintaining operational focus.
3Loss of information
If multiple work information parameters are displayed, then comprehensive monitoring is achieved, but the display complexity increases
Solution Approach 1:
The patent segments comprehensive work information into multiple discrete indicator types, each representing a specific parameter (work depth, height, POD, lifting weight, battery charging status). Each indicator is positioned separately within the operator's field of view, allowing comprehensive monitoring of all parameters without creating a complex centralized display. This segmentation simplifies the overall system while maintaining information completeness.
