Solution Overview

Problem

Existing LED lamps with emergency lighting functions suffer from low utilization of emergency lighting components under normal conditions, resource wastage, and cumbersome assembly/disassembly due to wired connections.

Innovation Solution

An LED lamp design featuring a detachable driving module and emergency module with plug-in terminals allowing easy switching between AC power operation and battery-powered operation, facilitated by a connector and emergency module that can be buckled to a first plug-in terminal for seamless electrical conduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an emergency lighting lamp is added to provide emergency lighting function, then the LED lamp can continue to operate after AC power is cut off, but the device complexity increases and resource utilization decreases due to having two separate LED lamps

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the main lighting lamp serve dual functions: normal lighting during AC power supply and emergency lighting during power outage. The same LED lamp structure is used for both purposes, eliminating the need for a separate emergency lighting lamp and reducing device complexity while maintaining continuous operation capability.

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

Solution Approach 2:

The patent merges the main lighting lamp and emergency lighting lamp into a single integrated unit. The LED lamp serves both as the main lighting source during normal operation and as the emergency lighting source during power outages, combining two previously separate functions into one unified system.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a standby power supply is connected to the main lighting lamp through a lead, then the LED lamp can operate during power outage, but the assembly and disassembly process becomes time-consuming and labor-consuming

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidassembly efficiency
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent divides the LED lamp into modular components: a lamp holder, a detachable driving module, and a power supply module. These segmented modules can be independently assembled and disassembled, greatly improving assembly efficiency while maintaining the emergency lighting function through the detachable connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a detachable driving module that can be connected or disconnected from the lamp holder. This dynamic connection allows the emergency lighting function to be activated or deactivated by simply plugging or unplugging the module, eliminating the need for complex wired connections and manual wiring during assembly and disassembly.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a detachable driving module is designed for easy assembly and disassembly, then the assembly efficiency is improved, but the engagement firmness may be compromised

Engineering Contradiction:
Improveassembly efficiencyVSAvoidengagement firmness
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent segments the driving module into a detachable unit with standardized connection interfaces. The lamp holder and driving module are designed with complementary connection structures that provide both ease of assembly and secure engagement, allowing quick replacement while maintaining reliable electrical and mechanical connections.

Inventive Principle:
Principle #1Segmentation

AI summary

The LED lamp comprises a light source, a driving module to drive the light source, a power supply module electrically connected to the driving module to supply power, a connector, and an emergency module. The driving module has a first plug-in terminal connected to the light source; the connector has a second, the emergency module a third. The two can alternate to put the lamp in two states: one, the connector's second terminal engages the driving module's first, enabling conduction between them and the light source; the other, the emergency module's third terminal engages the first, enabling conduction with the light source to drive it.
