Solution Overview

Problem

Existing energy management approaches in multi-dwelling units (MDUs) apply uniform maintenance and budgetary resources to HVAC units, leading to inefficiencies due to varying energy consumption across different spaces, resulting in reduced energy savings.

Innovation Solution

Implement a system to determine, normalize, and rank the energy consumption of each HVAC unit based on specific parameters such as occupancy, space size, sun exposure, and HVAC unit type, allowing for strategic allocation of resources to units with higher energy usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If uniform maintenance and budgetary resources are applied to each HVAC unit, then ease of operation is improved, but energy efficiency deteriorates

Engineering Contradiction:
Improveease of maintenanceVSAvoidenergy efficiency
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent applies local quality by transitioning from uniform maintenance across all HVAC units to differentiated maintenance based on each unit's actual energy consumption characteristics. The system identifies specific units with abnormal energy usage patterns and directs maintenance resources selectively to those units, making the maintenance approach locally adapted to each unit's needs rather than applying a blanket uniform approach.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes by monitoring and analyzing energy consumption parameters of each HVAC unit to identify deviations from expected patterns. By detecting changes in energy consumption parameters over time and comparing them against baseline data, the system dynamically adjusts maintenance priorities based on actual performance parameters rather than static uniform schedules.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If time-scheduled maintenance is applied to all HVAC units, then productivity is improved through systematic coverage, but energy savings deteriorate due to lack of prioritization

Engineering Contradiction:
Improvemaintenance coverageVSAvoidenergy savings
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements feedback by continuously monitoring energy consumption data from HVAC units and using this information to adjust maintenance prioritization. The system collects feedback on actual energy usage patterns, compares them against expected patterns, and uses this feedback loop to identify units requiring immediate attention, thereby optimizing the allocation of maintenance resources to maximize energy savings.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by transitioning from static time-scheduled maintenance to a dynamic maintenance prioritization system that adapts to changing energy consumption patterns. The system continuously updates maintenance priorities based on real-time and historical energy data, allowing the maintenance schedule to dynamically respond to actual unit performance and energy efficiency needs.

Inventive Principle:
Principle #15Dynamics
