Solution Overview

Problem

Existing methods lack an efficient way to identify and manage space utilization within buildings, leading to suboptimal maintenance and resource allocation due to varying occupancy levels across different spaces.

Innovation Solution

A method involving occupancy sensors that track usage data over time, calculate occupancy and utilization values, and adjust building operations to optimize space usage and maintenance schedules based on these values, including relocating equipment and adjusting maintenance frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If occupancy tracking and utilization analysis systems are implemented, then space utilization efficiency is improved, but device complexity and implementation cost increase

Engineering Contradiction:
Improvespace utilization efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system uses multi-functional occupancy sensors that not only detect presence but also track duration, frequency, and patterns of space usage. These sensors serve multiple purposes: occupancy detection, utilization calculation, maintenance scheduling, and equipment placement optimization, eliminating the need for separate systems for each function.

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

Solution Approach 2:

The system automatically calculates occupancy values and utilization values from sensor data without manual intervention. It self-adjusts maintenance schedules and provides recommendations for equipment relocation based on analyzed patterns, reducing the need for manual space management activities.

Inventive Principle:
Principle #25Self-service

2Reliability

If maintenance frequency is increased for high-utilization spaces, then reliability and cleanliness are improved, but loss of time and operational disruption increase

Engineering Contradiction:
Improvemaintenance qualityVSAvoidoperational disruption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The maintenance schedule is dynamically adjusted based on real-time occupancy patterns. High-utilization spaces receive more frequent maintenance, while low-utilization spaces receive less frequent maintenance. The system optimizes timing to perform maintenance during low-occupancy periods, minimizing disruption to building operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors occupancy data and uses this feedback to adjust maintenance schedules. Occupancy sensors provide ongoing information about space usage patterns, which automatically triggers appropriate maintenance frequency adjustments without manual intervention.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If equipment is relocated to optimize accessibility, then ease of operation is improved, but loss of time for relocation and setup increases

Engineering Contradiction:
Improveequipment accessibilityVSAvoidrelocation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system analyzes occupancy patterns over time to identify optimal equipment locations before relocation is performed. By预先 determining the best placement based on data-driven insights about user movement and space utilization, the system minimizes trial-and-error relocations and ensures equipment is placed in the most accessible positions from the outset.

Inventive Principle:
Principle #10Preliminary action

AI summary

Occupancy data over time is received for each of several spaces within a building from occupancy sensors that are disposed within each of the spaces. An occupancy value is determined for each of at least some of the several spaces based on the received occupancy data, each occupancy value representative of a percent of time that the respective space was occupied over an identified period of time. The space that had a highest occupancy value over the identified period of time is identified. A utilization value is determined for each of the spaces, wherein the utilization value is representative of a ratio of the occupancy value of the respective space and the highest occupancy value. An operation of the building is changed based at least in part on the utilization value of at least one of the plurality of spaces.
