Solution Overview

Problem

The process of building commissioning, particularly in HVAC systems, is time-consuming and prone to errors due to complex interactions between devices and sensors, often requiring extensive manual testing and occupancy-free training periods, which limits retro-commissioning and continuous commissioning opportunities.

Innovation Solution

An automated commissioning system using a controller with computer hardware and memory that connects devices and space sensors to verify expected behavior, checks wiring protocols, and reports results, allowing for efficient and systematic commissioning of devices and sensors in a physical space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual commissioning testing is performed to verify device and sensor operation, then commissioning accuracy and reliability are improved, but commissioning time and complexity increase significantly

Engineering Contradiction:
Improvecommissioning accuracyVSAvoidcommissioning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The commissioning system performs self-testing by automatically executing test routines that verify device and sensor operation without requiring extensive manual intervention. The system autonomously controls devices, reads sensor responses, and validates expected behaviors, enabling the building management system to commission itself with minimal human involvement while maintaining high accuracy through systematic automated verification protocols.

Inventive Principle:
Principle #25Self-service

2Reliability

If occupancy-free training periods are required for commissioning, then device-sensor relationship validation is improved, but adaptability for retro-commissioning and continuous commissioning deteriorates

Engineering Contradiction:
Improvedevice-sensor relationship validationVSAvoidretro-commissioning capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The commissioning system is designed to be dynamic and adaptable, allowing commissioning activities to occur during occupied periods rather than requiring fixed occupancy-free training periods. The system can adjust its testing protocols to work around building occupancy, perform commissioning in smaller incremental zones, and continue commissioning activities throughout the building lifecycle, thereby enabling retro-commissioning and continuous commissioning while maintaining validation reliability.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If extensive manual testing is performed to verify wiring protocols and device behavior, then commissioning thoroughness is improved, but device complexity and operational difficulty increase

Engineering Contradiction:
Improvewiring protocol verificationVSAvoidcommissioning operation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system replaces manual mechanical testing procedures with automated electronic control and measurement. The commissioning system electronically communicates with devices and sensors, automatically executes test sequences, and digitally verifies wiring protocols through structured query protocols, eliminating the need for manual wiring checks and physical device manipulation while maintaining thorough verification of installation correctness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If automated commissioning is implemented without occupancy-free periods, then retro-commissioning and continuous commissioning are enabled, but measurement precision of device-sensor relationships may deteriorate

Engineering Contradiction:
Improvecontinuous commissioning capabilityVSAvoiddevice-sensor relationship accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The commissioning system divides the building into smaller commissioning zones or subsystems that can be tested and validated independently during occupied periods. By segmenting the commissioning process into manageable units, the system can achieve precise measurement of device-sensor relationships in each zone without requiring the entire building to be vacant, thereby maintaining measurement precision while enabling continuous commissioning capability.

Inventive Principle:
Principle #1Segmentation
