Solution Overview

Problem

Conventional navigation systems do not have a function to alleviate traffic jams or control the traffic environment effectively, limiting their ability to optimize the route and arrival time for drivers.

Innovation Solution

An environment adjustment system that acquires and analyzes traffic information, drafts action plans to recommend routes that avoid congested areas, and incentivizes users to perform these plans, using IoT devices and a server to monitor and adjust traffic conditions dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional navigation systems recommend routes to individual users, then individual users can reach their destinations efficiently, but traffic jams in the overall environment cannot be alleviated

Engineering Contradiction:
Improveindividual travel timeVSAvoidoverall traffic flow efficiency
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The system implements a feedback mechanism where user route selection behavior is monitored and fed back into the route recommendation algorithm. The server collects information about which recommended routes users actually take and uses this feedback to adjust future route recommendations, thereby coordinating individual decisions with overall traffic optimization goals

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The route recommendation system dynamically adjusts its behavior based on real-time traffic conditions and accumulated user response data. The recommendation strategy changes from static individual optimization to dynamic collective optimization, where the system adapts its recommendations to guide users toward routes that optimize overall traffic flow

Inventive Principle:
Principle #15Dynamics

2Productivity

If the system recommends action plans to optimize overall traffic environment, then traffic jams can be alleviated, but user compliance with recommended plans decreases

Engineering Contradiction:
Improvetraffic environment optimizationVSAvoiduser compliance rate
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system introduces an intermediary incentive mechanism (points, rewards, or other benefits) that mediates between the system's traffic optimization goals and user preferences. This intermediary reward system bridges the gap by making compliance with recommended routes beneficial for users, thereby increasing compliance rates while achieving traffic optimization

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the parameter of user motivation by introducing incentive parameters (rewards, points, benefits) that alter user behavior. By modifying the incentive structure rather than relying solely on route quality, the system increases user compliance with recommended action plans that optimize overall traffic

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the system monitors and confirms user performance of action plans, then environmental optimization can be achieved, but system complexity increases

Engineering Contradiction:
Improveenvironmental adjustment effectivenessVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements self-service monitoring where users automatically report their route compliance through their navigation devices, and the server automatically processes this information. This self-service approach reduces the need for complex manual monitoring infrastructure while maintaining effective environmental optimization through automated feedback processing

Inventive Principle:
Principle #25Self-service

AI summary

An environment adjustment system includes an acquisition unit configured to acquire environmental information of an environment related to a user, a drafting unit configured to draft an action plan to recommend to the user based on the environmental information, a transmission unit configured to transmit the action plan to the user's terminal, and a confirming unit configured to confirm whether the user has performed the action plan. When the drafting unit drafts a new action plan for another user or for the user, it drafts the new action plan using a result of the confirmation by the confirming unit.
