Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating environmental contribution of user behavior do not consider individual circumstances such as place of residence and family structure, making it difficult to ascertain a sustainable level of eco-behavior.
Innovation Solution
A user behavior evaluation device that includes an environmental impact calculation portion, a coefficient derivation portion, and a behavior evaluation portion to calculate a sustainable score based on user-specific factors like location, traffic conditions, communication plan, electricity usage, and purchase history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standardized CO2 emission calculation method is used, then the calculation process is simple, but the evaluation does not reflect individual user circumstances
Solution Approach 1:
The patent applies local quality by introducing user-specific coefficients (α, β, γ) that customize the evaluation for each user based on their circumstances such as place of residence, family structure, and behavior patterns. This allows the standardized calculation framework to be adapted locally to each user's situation, resolving the contradiction between calculation simplicity and user-specific evaluation accuracy.
Solution Approach 2:
The patent implements dynamics by making the evaluation coefficients variable rather than fixed. The coefficients α, β, and γ can be dynamically adjusted based on user attributes and behavior data, allowing the system to adapt to changing user circumstances while maintaining a structured calculation approach.
2Measurement precision
If user-specific coefficients are introduced, then the evaluation accuracy improves, but the calculation complexity increases
Solution Approach 1:
The patent uses parameter changes by introducing adjustable coefficients (α, β, γ) that modify the base CO2 emission calculation. These parameters can be changed based on user attributes without fundamentally altering the calculation structure, thereby improving evaluation accuracy while controlling system complexity through a modular approach.
3Adaptability or versatility
If multiple user attributes are considered, then the evaluation becomes more personalized, but the data processing requirement increases
Solution Approach 1:
The patent extracts only the essential user attributes needed for coefficient determination (place of residence, family structure, and representative behavior patterns) rather than processing all possible user data. This selective extraction approach enables personalization while controlling data processing requirements by focusing on the most impactful factors.
