Solution Overview

Problem

Current explosion-proof lamps have insufficient structural strength and inadequate heat dissipation, leading to reduced safety and service life due to potential ignition risks and performance degradation from high temperatures.

Innovation Solution

The design incorporates a structure strengthening ring between the lamp cover and light source module with protrusion portions and recesses for enhanced structural integrity, a multi-layer sealing system for improved leakproofness, and a heat dissipation structure with fins and a streamlined wall to manage heat effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the structural strength of explosion-proof lamps is increased, then safety is improved, but device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The strengthening ring is divided into multiple protrusion portions (first and second protrusion portions) arranged in a staggered manner, which segments the structural reinforcement into discrete elements. This segmentation allows the ring to distribute external forces more effectively while maintaining a manageable level of structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The strengthening ring introduces a new dimensional element between the lamp cover and light source module, creating an additional layer of structural reinforcement. This dimensional addition strengthens the overall structure without requiring a complete redesign of the existing lamp components

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Temperature

If heat dissipation structure is added, then heat dissipation performance is improved, but device complexity increases

Engineering Contradiction:
Improveheat dissipation performanceVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The heat dissipation fins are integrated with the streamlined wall structure, merging two functional elements into a unified component. This combination allows the wall to serve both as a protective barrier and as a heat dissipation pathway, reducing the need for separate heat dissipation structures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The streamlined wall adopts a curved surface design that facilitates heat dissipation through improved thermal convection. The curved geometry allows for more efficient heat transfer from the light source module to the surrounding environment, enhancing heat dissipation performance

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If multiple sealing rings are added, then leakproofness is improved, but device complexity increases

Engineering Contradiction:
ImproveleakproofnessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing system is segmented into multiple sealing rings positioned at different locations (between upper cap and main housing, between lower cap and main housing). This segmentation ensures comprehensive sealing coverage and provides redundant sealing pathways, significantly improving leakproofness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing rings act as intermediary elements between the caps and main housing, creating a protective barrier that prevents gas leakage. These intermediary sealing components ensure that even if one sealing pathway fails, alternative sealing paths remain intact

Inventive Principle:
Principle #24Intermediary (Mediator)
