Solution Overview

Problem

Existing systems face challenges in efficiently collecting and aggregating individual preferences to optimize environmental conditions in buildings, leading to over-cooling and over-heating, which increases energy consumption and reduces occupant comfort due to high transaction costs associated with traditional feedback methods.

Innovation Solution

A system and method that deploy feedback devices to collect preference feedback in real-time, aggregate data using fuzzy variables, and adjust environmental conditions like temperature to maintain or move group preferences within a certain range, utilizing a network of sensors and processors to minimize transaction costs and improve comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional feedback methods (surveys, paperwork, computer forms) are used to collect individual preferences, then preference information can be obtained, but transaction costs are high and response rates are low

Engineering Contradiction:
Improvepreference informationVSAvoidtransaction cost
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system implements continuous automated feedback collection through sensors and digital interfaces that monitor environmental conditions and automatically gather preference data from occupants. This eliminates manual survey processes and creates an ongoing feedback loop where preferences are collected, aggregated, and used to adjust environmental settings automatically, significantly reducing transaction costs and time requirements.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables occupants to provide preference feedback through simple self-service mechanisms such as digital buttons, mobile applications, or automated sensors that detect occupancy and environmental conditions. This self-service approach eliminates the need for manual survey administration and processing, allowing individuals to contribute preference data effortlessly while the system automatically aggregates and processes the information.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If building environmental conditions are preset to a single temperature, then system operation is simple, but most buildings are over-cooled or over-heated leading to energy waste and occupant dissatisfaction

Engineering Contradiction:
Improvesystem operationVSAvoidenergy waste
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system transitions from static preset temperature control to dynamic environmental adjustment based on real-time aggregated group preferences. Sensors continuously monitor environmental conditions and occupancy, while the system automatically adjusts temperature, lighting, and other environmental parameters to match current group preferences, eliminating both over-cooling and over-heating while maintaining simple operation through automation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system dynamically changes environmental parameters such as temperature, humidity, and lighting levels based on aggregated group preferences rather than maintaining fixed preset values. This parameter adjustment is driven by continuous feedback from occupants and automated sensors, allowing the building to adapt to changing conditions and preferences while optimizing energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If individual preferences are collected and aggregated to form group preferences, then occupant comfort can be improved, but the complexity of collecting and processing individual data increases

Engineering Contradiction:
Improveoccupant comfortVSAvoiddata collection and aggregation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system merges individual preference data into aggregated group preferences using automated processing algorithms. Multiple individual inputs from various occupants are combined and processed to determine the collective group preference, which is then used to adjust environmental conditions. This merging process simplifies the complexity by automatically aggregating data rather than requiring manual analysis of individual responses.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system introduces an intermediary automated processing layer between individual preference inputs and environmental control adjustments. This intermediary component aggregates individual data points, processes them through algorithms to determine group preferences, and translates them into environmental settings, thereby reducing the complexity of directly managing individual data while improving reliability of comfort outcomes.

Inventive Principle:
Principle #24Intermediary (Mediator)
