Solution Overview
Problem
Existing methods for determining the charge state of energy supply sources for road construction machines are insufficient in accurately assessing whether the energy supply can complete a predetermined work project, lacking clarity on remaining usage capacity in terms of time, range, or area.
Innovation Solution
A unit that displays the remaining usage capacity of energy supply sources connected to road construction machines in terms of usage time, range, or area, based on current charge state, allowing for efficient determination and display, and optionally includes user-friendly interfaces for manual or automatic adjustments, considering current operating conditions and target conditions for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the state of charge is displayed only as a percentage, then the display is simple, but the accuracy of determining whether the electrical load can complete a predetermined task is insufficient
Solution Approach 1:
The patent segments the single percentage-based state of charge display into multiple dimensional representations: remaining operating time, remaining operating range, and remaining operating area. Each dimension provides specific information about the energy supply's capacity to complete particular tasks, transforming one vague percentage into three concrete, task-relevant metrics that together provide comprehensive accuracy while maintaining display simplicity through modular presentation.
2Measurement precision
If the remaining service life is displayed in multiple dimensions (time, range, area), then the accuracy of task completion assessment is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal display system that calculates and presents all three dimensions of remaining service life (time, range, area) using a single integrated calculation framework based on the energy supply's power characteristics and the consumer's power demand. This multi-functional approach allows the same system to serve multiple assessment purposes simultaneously without requiring separate measurement devices for each dimension, thereby improving accuracy while controlling complexity through systematic design.
