Solution Overview

Problem

Hospitals face inefficiencies in operating room utilization, leading to longer patient wait times, surgeon overtime, and waste of resources due to varying utilization rates among operating rooms.

Innovation Solution

An operating room allocation apparatus and method that calculates utilization rates by time period, adjusting them to an appropriate range using average utilization rates, and allocates rooms to minimize deviations, optimizing resource use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If operating rooms are allocated without considering time-period utilization rates, then allocation is simple, but utilization rates vary greatly leading to surgeon overtime and resource waste

Engineering Contradiction:
Improveoperating room utilization efficiencyVSAvoidallocation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the operating room utilization analysis by time periods (morning, afternoon, evening shifts) and calculates separate utilization rates for each period. This segmentation allows the system to identify peak and off-peak periods, enabling more precise allocation decisions that prevent surgeon overtime while optimizing resource use during low-demand periods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a dynamic allocation system that adjusts operating room assignments based on real-time and historical utilization data. The system continuously monitors utilization rates across different time periods and dynamically reallocates rooms to balance workload, preventing both over-utilization (overtime) and under-utilization (resource waste).

Inventive Principle:
Principle #15Dynamics

2Loss of time

If operating rooms are allocated without time-period consideration, then allocation process is simple, but patient wait times increase due to non-operating time

Engineering Contradiction:
Improvepatient wait timeVSAvoidallocation system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of historical utilization data to predict future demand patterns. By identifying which time periods are most likely to have high demand, the system proactively allocates operating rooms in advance, reducing patient wait times before surgeries are scheduled rather than reacting after assignments are made.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms that continuously monitor actual utilization rates against target values. When deviations are detected, the system automatically adjusts future allocations to correct imbalances, ensuring that patient wait times are minimized while maintaining appropriate surgical schedules across all time periods.

Inventive Principle:
Principle #23Feedback
