Solution Overview
Problem
Existing vehicle range display systems fail to provide reliable and anxiety-reducing information about the remaining range and charging options relative to a navigation route, leading to uncertainty and anxiety among electric vehicle users.
Innovation Solution
A method and device that visually display the vehicle's actual range as a graphical object divided into minimum and maximum ranges, with additional sections indicating the necessity of energy-saving driving or charging stops, and optionally include acoustic signals to manage range anxiety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vehicle body is enlarged to accommodate more sensors and batteries, then the sensing and power supply capabilities are improved, but the portability and ease of movement are worsened
Solution Approach 1:
The vehicle body is divided into a first vehicle body portion and a second vehicle body portion that can be separated from each other. The first portion contains the sensor array while the second portion contains the battery pack and display device. This segmentation allows the sensors to be portable and easy to move, while the battery can remain stationary or be positioned separately, thus resolving the contradiction between having sufficient sensing capability and maintaining portability.
2Area of stationary object
If multiple sensors are arranged in a large area, then the field of view and detection coverage are improved, but the device complexity and space requirements are worsened
Solution Approach 1:
The sensor array is segmented into multiple independent sensors distributed across the first vehicle body portion, with each sensor capable of independent operation. This segmentation simplifies the overall device complexity while maintaining large area coverage, as each sensor is a standardized component rather than a complex integrated system.
Solution Approach 2:
Each sensor in the array is designed to perform multiple functions including detecting light, sound, heat, motion, and other environmental parameters. This multi-functionality allows a single sensor type to provide comprehensive environmental awareness, reducing the need for specialized sensors for each function and thereby simplifying the overall device complexity while maintaining extensive detection coverage.
