Solution Overview

Problem

Outdoor landscape lighting fixtures deteriorate due to UV damage, leading to reduced visual appeal and potential safety and security issues, necessitating frequent replacements and increased maintenance costs.

Innovation Solution

A retractable landscape light device that retracts into a base buried underground when not in use, featuring a UV-resistant top cover and automated raising/lowering mechanisms controlled by timers or light sensors, ensuring protection from UV exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the light fixture is installed above ground for illumination, then the lighting function is achieved, but the fixture is exposed to UV damage causing deterioration

Engineering Contradiction:

Improvelighting functionVSAvoidUV damage

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The light fixture transitions from a static above-ground installation to a dynamic system that can extend above ground for illumination and retract below ground for protection. The telescopic mechanism enables the fixture to change its position dynamically, allowing it to occupy two states: extended for lighting function and retracted for UV protection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The light fixture is nested within a telescopic housing structure that allows it to be contained within the base when retracted. The telescopic sections provide a protective enclosure that shields the light fixture from UV exposure while maintaining the ability to extend for illumination.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If the light fixture remains above ground for continuous illumination, then the lighting function is maintained, but the fixture requires frequent replacement due to UV deterioration

Engineering Contradiction:

Improvecontinuous illuminationVSAvoidfixture longevity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The light fixture operates in periodic cycles, extending above ground during illumination periods and retracting below ground during non-use periods. This periodic extension and retraction allows the fixture to perform its lighting function when needed while being protected from UV damage during storage, thereby extending its operational lifespan and reducing replacement frequency.

Inventive Principle:

Principle #19Periodic action

3Shape

If the light fixture is made visible above ground, then the aesthetic function is achieved, but the fixture becomes vulnerable to weathering and damage

Engineering Contradiction:

Improvevisual appealVSAvoidresistance to weathering

Core Design Contradiction:

ShapeVSStrength

Solution Approach 1:

The fixture dynamically adjusts its visibility by extending above ground when aesthetic display is desired and retracting below ground when protection from weathering is needed. This dynamic positioning allows the same fixture to fulfill both aesthetic and protective requirements at different times.

Inventive Principle:

Principle #15Dynamics

AI summary

A retractable landscape light device is provided. The device is comprised of a retractable landscape light device that provides a landscape light that is stored under a ground surface when not in use and raises from the ground surface when in the use. The light can be automatically raised/lowered via a timer or a light sensor or may be controlled via a mobile application.
