Solution Overview

Problem

The existing light-emitting systems, particularly those using LEDs, face a risk of disconnection between the connection cable and the support due to vibrations or shocks, leading to potential accidents when installed in motor vehicle lighting devices.

Innovation Solution

A light-emitting system with a fixed mechanical connection between the connection socket and the support, utilizing a first and second cooperation member that engage and lock, forming an embedding connection, ensuring no degree of freedom and thus preventing detachment under external stresses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional connector is used to connect the connection cable to the support, then the assembly is simple and quick, but the connection is vulnerable to detachment due to vibrations and shocks

Engineering Contradiction:
Improveconnection stabilityVSAvoidconnection structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the connector with the support structure by integrating the first cooperation element directly into the support. This eliminates the separate connector component while maintaining the electrical connection function, thereby improving reliability without significantly increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection plug is nested within the support structure through the integration of the first cooperation element. The second cooperation element on the plug engages with the first cooperation element embedded in the support, creating a nested arrangement that secures the connection against vibrations and shocks.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If the connector is securely fixed to prevent detachment, then connection reliability improves, but the assembly and disassembly process becomes more complex

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly and disassembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs a dynamic locking mechanism where the second cooperation element on the connection plug engages with the first cooperation element on the support. This engagement provides secure fixation during operation while allowing for controlled assembly and disassembly when needed, balancing reliability with ease of operation.

Inventive Principle:
Principle #15Dynamics
