Solution Overview

Problem

Surgical lights often fail due to power outages, voltage fluctuations, and cable breaks, leading to interruptions in surgical operations, and existing solutions require large and costly external emergency power supplies.

Innovation Solution

Integrating a rechargeable battery and charging system directly into the surgical light's body, allowing for a compact emergency power supply that ensures continuous operation without external wiring, using a combination of LEDs, control electronics, and advanced accumulator technologies like lithium polymer batteries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a central emergency power supply is used, then reliability during power outages is improved, but device complexity and installation space requirements increase

Engineering Contradiction:
Improvereliability during power outagesVSAvoidinstallation space requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the emergency power supply function from the central system and segments it into individual surgical lights. Each light contains its own accumulator (battery) integrated into the light body, allowing independent operation during power outages without requiring a centralized emergency power infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The emergency power supply capability is extracted from the central building infrastructure and embedded directly into the surgical light itself. This removes the dependency on external emergency power systems while maintaining reliability during power failures.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If accumulators are integrated into the light body, then installation space efficiency is improved, but heat management becomes more challenging

Engineering Contradiction:
Improveinstallation space efficiencyVSAvoidheat management
Core Design Contradiction:
Volume of moving objectVSTemperature

Solution Approach 1:

The patent merges the accumulator with the light body structure, integrating the battery directly into the housing. This combined design optimizes space utilization while the housing itself serves as a thermal management structure for the integrated power source.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies different thermal management approaches to different components within the light body. The housing material and structure are specifically designed to provide thermal isolation and heat dissipation pathways for the accumulator, while maintaining the required space efficiency.

Inventive Principle:
Principle #3Local quality
