Solution Overview

Problem

Electric vehicle users face challenges in reaching their destinations due to insufficient battery charge, and existing energy-saving mode technologies require manual activation and deactivation, leading to inefficient power management.

Innovation Solution

A method for energy-saving driving that automatically determines and activates energy-saving mode sections of a route based on the vehicle's battery charge level and driving conditions, minimizing power loss and extending the available driving distance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the energy-saving mode is activated manually by the user, then the power consumption is reduced, but the user convenience deteriorates due to the need for separate input operations

Engineering Contradiction:

Improvepower consumptionVSAvoiduser convenience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The navigation system automatically determines and activates energy-saving mode driving sections without requiring user input. The system analyzes the route, battery charge amount, and traffic conditions to autonomously decide when to activate energy-saving mode, making the system serve itself rather than requiring manual user control.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent applies strong electronic control to accelerate the activation of energy-saving mode. By using robust electronic control signals, the system can quickly and reliably activate energy-saving mode in identified sections, ensuring the transition is swift and decisive rather than gradual or uncertain.

Inventive Principle:

Principle #38Strong oxidants (Accelerated oxidation)

2Device complexity

If the energy-saving mode restricts only the output of the electric vehicle, then the implementation complexity is low, but the available driving distance extension is insufficient

Engineering Contradiction:

Improveimplementation complexityVSAvoidavailable driving distance

Core Design Contradiction:

Device complexityVSDuration of action of moving object

Solution Approach 1:

The patent segments the driving route into multiple sections, identifying specific portions where energy-saving mode should be activated. By dividing the route and analyzing each section's characteristics (traffic congestion, power requirements), the system can strategically apply energy-saving mode to maximize driving distance extension while maintaining manageable implementation complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The navigation system performs preliminary analysis of the route, battery charge amount, and traffic conditions before the user starts driving. This advance planning allows the system to pre-determine optimal energy-saving mode sections, ensuring maximum driving distance extension is achieved without requiring complex real-time adjustments during driving.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the energy-saving mode is activated automatically based on driving state, then the user convenience is improved, but the device complexity increases due to additional control functions

Engineering Contradiction:

Improveuser convenienceVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The navigation system performs multiple functions: it provides route guidance, analyzes traffic conditions, monitors battery charge amount, and determines energy-saving mode sections. By making the navigation system universal and multi-functional, the patent avoids adding separate dedicated hardware or control systems, thereby improving user convenience without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Duration of action of moving object

If the electronic control function is deactivated to save power, then the available driving distance is extended, but the reliability deteriorates due to loss of control functions

Engineering Contradiction:

Improveavailable driving distanceVSAvoidreliability

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent applies energy-saving mode selectively to specific local sections of the route rather than deactivating electronic control functions throughout the entire driving journey. By identifying particular sections where energy-saving mode is most beneficial (such as traffic congestion sections), the system maintains reliability in areas where full control is needed while extending driving distance in areas where reduced control is acceptable.

Inventive Principle:

Principle #3Local quality

AI summary

Methods and systems of a mobility device for energy-saving driving are described. According to one embodiment, a method comprises receiving a guide request of a first route to a first destination, comparing an amount of power required for driving of the first route with a battery charge amount of the mobility device, and determining a portion of the first route as an energy-saving mode driving section when it is determined that the battery charge amount of the mobility device for reaching the first destination is insufficient as a result of the comparison.
