Solution Overview

Problem

Conventional methods for evaluating user satisfaction in multi-environmental settings, such as thermal and light environments, fail to account for the mutual influences between different environmental indexes, leading to incomplete satisfaction level assessments.

Innovation Solution

A satisfaction level calculation device that includes individual calculating units for each environmental index and an overall calculating unit to combine these individual satisfaction levels into a comprehensive assessment of the space environment, allowing for a more accurate evaluation of user satisfaction across multiple indexes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only a single environmental index satisfaction level (e.g., thermal environment) is calculated, then the calculation method is simple, but the user's overall satisfaction level with the environment cannot be accurately determined

Engineering Contradiction:
Improvesatisfaction level assessment accuracyVSAvoidcalculation system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent divides the overall satisfaction assessment into multiple individual satisfaction assessments for different environmental indexes (thermal environment, light environment, air environment, etc.). Each index is evaluated separately using its own satisfaction level calculation method, and then these individual assessments are integrated to determine the overall satisfaction level. This segmentation allows for comprehensive evaluation while maintaining clarity in each individual assessment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple individual satisfaction levels from different environmental indexes into a single overall satisfaction level. By merging the assessment results from thermal environment, light environment, air environment, and other indexes, the system achieves a comprehensive evaluation of user satisfaction with the entire space environment, resolving the limitation of single-index assessment.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If multiple environmental indexes are evaluated independently, then each index can be assessed accurately, but the mutual influences between different environmental indexes are not captured

Engineering Contradiction:
Improveindividual index assessment accuracyVSAvoidmutual influence information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent merges multiple individual satisfaction levels into an overall satisfaction level that reflects the combined effect of different environmental indexes. This integration process captures the mutual influences between indexes (such as how lighting affects thermal perception) by combining the individual assessments in a way that represents the user's holistic experience of the environment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal satisfaction level calculation framework that can handle multiple environmental indexes simultaneously. The system is designed to evaluate various indexes (thermal, light, air, etc.) using a unified approach that accounts for their interrelationships, making the assessment system multi-functional and adaptable to different environmental conditions and their interactions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A satisfaction level calculation device (10) acquires environmental data detected by each of a plurality of environment sensors (20). The satisfaction level calculation device (10) sets each of a plurality of indexes about a space environment as a target index. The satisfaction level calculation device (10) calculates, from the environmental data acquired by measuring the target index, an individual satisfaction level, which is a satisfaction level of the target index. The satisfaction level calculation device (10) calculates, from the individual satisfaction level about each of the plurality of indexes, an overall satisfaction level, which is an overall satisfaction level about the space environment.
