Solution Overview

Problem

Personal mobility service areas are not effectively adjusted based on real-time congestion levels and pedestrian emotions, leading to suboptimal user experience and operational inefficiencies.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the service area is fixed and not adjusted dynamically, then the service area boundary is stable and easy to manage, but the service area cannot adapt to real-time congestion levels and pedestrian emotions, leading to suboptimal user experience

Engineering Contradiction:
Improveservice area adaptabilityVSAvoidservice area control complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The service area boundary is transformed from a static geo-fence to a dynamic boundary that automatically adjusts based on real-time congestion levels and pedestrian emotions. The controller continuously receives image data, determines current congestion and emotion states, and modifies the service area boundary accordingly, enabling the system to adapt to changing environmental conditions while maintaining manageable complexity through automated control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where the controller continuously monitors pedestrian emotions and congestion levels through image data, compares these against reference values, and adjusts the service area boundary in response. This closed-loop control enables the service area to adapt dynamically while the controller manages the complexity of real-time adjustments based on emotional and congestion feedback.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the service area is expanded to include more areas, then user mobility is improved, but operational efficiency decreases due to increased service delivery complexity

Engineering Contradiction:
Improveuser mobilityVSAvoidoperational efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The service area boundary dynamically adjusts its size and position based on real-time conditions. When pedestrian emotions are positive and congestion is low, the boundary expands to allow greater user mobility. When emotions turn negative or congestion increases, the boundary contracts to maintain operational efficiency. This dynamic adjustment resolves the contradiction by making service area size contingent on current environmental factors rather than fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the spatial parameters of the service area (boundary position, area size) based on detected emotional states and congestion levels. By adjusting these parameters dynamically, the system optimizes both user mobility and operational efficiency - expanding when conditions permit and contracting when necessary to maintain productivity.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the service area is reduced to improve operational efficiency, then service delivery is optimized, but user experience deteriorates due to limited mobility

Engineering Contradiction:
Improveoperational efficiencyVSAvoiduser mobility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

Rather than maintaining a fixed reduced service area, the system dynamically adjusts the boundary based on real-time conditions. When operational efficiency is compromised by negative emotions or high congestion, the boundary contracts. When conditions improve, the boundary expands to restore user mobility. This dynamic approach ensures operational efficiency is maintained only when necessary while preserving user experience when conditions allow.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The service area parameters (boundary position, area size) are continuously adjusted based on emotional and congestion data. The system reduces the service area parameter values when operational efficiency requires it, but increases them when user experience can be improved, creating a dynamic balance between productivity and ease of operation rather than a fixed compromise.

Inventive Principle:
Principle #35Parameter changes

4Measurement precision

If real-time image data processing is implemented to determine congestion and emotions, then service area adjustment accuracy is improved, but system complexity and processing requirements increase

Engineering Contradiction:
Improvecongestion and emotion detection accuracyVSAvoidimage processing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The controller serves as an intermediary that receives image data, processes it to determine congestion levels and pedestrian emotions, and uses these determinations to adjust the service area boundary. This intermediary processing layer enables accurate measurement of emotional states and congestion without requiring the entire system architecture to become overly complex, as the controller centralizes the image processing functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces traditional mechanical or manual methods of determining service area boundaries with optical-based image processing. By using image data analysis to detect pedestrian emotions and congestion levels, the system achieves high measurement precision while substituting complex mechanical adjustment mechanisms with automated visual processing and digital control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
