Innovation Solution

A method and device using an evaluation device and display/operating device that determine nearby electric charging stations, provide immediate feedback on selected charging times or SOC values, and allow users to pre-select charging options, enabling direct control over operating strategies for hybrid and electric vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If charging stations are displayed without providing feedback on charging time and operating strategy changes, then the system complexity is reduced, but the user cannot optimize charging planning for fuel efficiency and electrical potential utilization

Engineering Contradiction:
Improvecharging planning optimizationVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system displays feedback information showing how selected charging times affect the operating strategy and fuel efficiency. This allows users to optimize their charging planning by seeing the direct impact of their choices on vehicle operation modes and energy consumption patterns.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system calculates and displays multiple future operating strategies in advance based on different charging time selections. Users can review these pre-calculated strategies before making their final charging decision, enabling informed optimization without real-time computation delays.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If multiple future operating strategies are displayed based on selected charging times, then user feedback and optimization capability are improved, but the information processing and display complexity increases

Engineering Contradiction:
Improveuser feedback informationVSAvoidinformation processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The information is segmented into distinct components: charging time selection, multiple future operating strategies, and their interrelationships. Each element is displayed separately and systematically, making complex information more manageable and comprehensible for users.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system adds a temporal dimension by displaying multiple future operating strategies corresponding to different charging time selections. This transforms a single-point decision into a multi-temporal view, allowing users to understand the evolution of operating strategies over time based on their charging choices.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the system allows user selection of charging times with immediate feedback on operating strategy changes, then charging planning flexibility is improved, but the computational requirements and processing time increase

Engineering Contradiction:
Improvecharging planning flexibilityVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-calculates multiple future operating strategies in advance and stores them for quick retrieval. When users select different charging times, the system immediately displays the corresponding pre-computed strategies without requiring real-time calculation, thus maintaining flexibility while minimizing processing time.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If charging stations are determined and displayed without providing options for charging time selection, then the device operation is simplified, but users cannot control or optimize their operating strategy

Engineering Contradiction:
Improvedevice operation simplicityVSAvoidoperating strategy control
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static display of charging stations to a dynamic interface where users can select different charging times and immediately see how this affects future operating strategies. This dynamic interaction maintains operational simplicity while enabling comprehensive control and optimization capabilities.

Inventive Principle:
Principle #15Dynamics
