Solution Overview

Problem

Decorative lamps used outdoors face issues with poor waterproof performance and high production costs due to glue filling processes, leading to potential failure from water vapor condensation and low efficiency in assembly.

Innovation Solution

A lamp design incorporating an elastic waterproof layer made of silicone material, which fills the gap between the lens and base, and allows the lamp component to pass through, enhancing waterproofing and enabling automatic assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a glue filling process is used to waterproof lamps, then waterproofing is attempted, but the waterproof performance is poor and production cost is high

Engineering Contradiction:

Improvewaterproof performanceVSAvoidproduction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive glue filling with a low-cost rubber stopper that can be easily manufactured and installed. The rubber stopper is a simple, inexpensive component that provides effective waterproofing without the high material and labor costs associated with glue filling processes.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces the chemical bonding mechanism of glue filling with a mechanical sealing approach using a rubber stopper. The stopper is inserted into a groove and compressed to create a physical seal, eliminating the need for chemical adhesives and simplifying the manufacturing process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a glue filling process is used to waterproof lamps, then waterproofing is attempted, but production efficiency is low

Engineering Contradiction:

Improvewaterproof performanceVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The rubber stopper is pre-formed and ready for installation, eliminating the need for on-site glue application and curing time. The stopper can be quickly inserted into the groove during assembly, significantly speeding up the production process compared to glue filling which requires precise application and drying time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The rubber stopper is designed to be self-installing into the groove structure. The compression and elastic recovery of the stopper create the seal automatically upon insertion, without requiring additional bonding steps or specialized application equipment, thereby improving production efficiency.

Inventive Principle:

Principle #25Self-service

3Device complexity

If external water vapor enters the lamp interior, then the lamp structure is simple, but water vapor condenses on the inner wall causing lighting failure

Engineering Contradiction:

Improvelamp structureVSAvoidlighting reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The rubber stopper acts as an intermediary sealing element between the external environment and the lamp interior. It physically blocks water vapor from entering through the opening, preventing condensation on internal surfaces while maintaining the simplicity of the overall lamp structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The rubber stopper utilizes the elastic properties of rubber material to create an effective seal. The flexible nature of the rubber allows it to conform to the groove geometry and maintain sealing pressure, effectively preventing water vapor ingress while keeping the structural design simple.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

Disclosed is a lamp including a lamp housing, a lamp component, and an elastic waterproof layer. The lamp housing may comprise an accommodating space and a plurality of penetrating through holes. The lamp component and the elastic waterproof layer may be both disposed in the accommodating space. At least one of an upper structure and/or a side structure of the lamp component may extend out of the lamp housing through a corresponding penetrating through hole. The elastic waterproof layer may be connected to an inner bottom wall of the lamp housing and the lamp component separately to fill a gap between the lamp component and the inner bottom wall of the lamp housing. The elastic waterproof layer may be provided with two mounting through holes along a radial direction of the lamp, and the side structure of the lamp may be configured to pass through the mounting through hole.
