Dynamic Environmental Load Assessment Using Life-Cycle State Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing environmental load simulation technologies fail to account for dynamic changes in biological or ecological systems when evaluating products introduced into them, such as pharmaceuticals and bioplastics, leading to inaccurate assessments.
Innovation Solution
An information processing device and method that estimates dynamic changes in biological or ecological systems using life cycle models, calculates environmental loads, and corrects them based on quality-of-life indices to provide accurate assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a product is introduced into a biological system or ecological system, then the product can serve its intended function, but the state of the biological system or ecological system may dynamically change, causing inaccurate environmental load assessment
Solution Approach 1:
The patent applies dynamics by transitioning from static environmental load assessment to dynamic assessment that captures temporal changes in biological and ecological systems. The life cycle model simulates state transitions over time, allowing the assessment to adapt to changing system conditions rather than relying on fixed baseline data.
Solution Approach 2:
The patent changes assessment parameters by introducing time-dependent variables and state transition probabilities. Instead of using constant environmental load factors, the system updates parameters dynamically based on simulated biological or ecological state changes, enabling accurate reflection of evolving system conditions.
2Ease of operation
If traditional life cycle assessment methods are used, then the assessment process is simple and straightforward, but dynamic changes in biological or ecological systems are not considered
Solution Approach 1:
The patent creates a virtual copy or simulation model of the biological or ecological system through the life cycle model. This digital twin allows assessment of dynamic changes without requiring complex real-time monitoring of actual biological systems, maintaining ease of operation while improving reliability through simulated state transitions.
3Measurement precision
If dynamic changes in biological or ecological systems are considered, then environmental load assessment accuracy improves, but the complexity of the assessment model increases
Solution Approach 1:
The patent segments the complex biological or ecological system into discrete states and transition pathways within the life cycle model. By dividing the continuous dynamic system into manageable state segments with defined transition probabilities, the model captures complexity without becoming computationally intractable or difficult to implement.

AI summary
An information processing device holds: a life cycle model indicating information for estimating a dynamic change of states of a biological system or an ecological system into which the target product is introduced, and the target product and a used item other than the target product used in each state; environmental load information indicating an environmental load of each of the target product and the used item; and index information indicating an index relating to, for each state, a quality of life of the biological system or the ecological system affected by the target product, and estimates the dynamic change of the states based on the life cycle model; calculates the environmental load and the index in an entire period of the estimated dynamic change with reference to the environmental load information and the index information; and corrects the calculated environmental load based on the calculated index.
