Solution Overview

Problem

Conventional light fixtures do not effectively distribute light through liquids, limiting their ability to create unique and efficient lighting effects in environments.

Innovation Solution

A light fixture design that incorporates a vessel filled with a liquid, where the light source is positioned within or surrounded by the vessel, allowing light to pass through the liquid and be distributed in a novel manner, utilizing a light receiver, light guide, and mounting structure for optimal light dispersal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional light fixtures are used, then the structure is simple and easy to manufacture, but the light distribution through liquid is ineffective and lacks unique lighting effects

Engineering Contradiction:
Improvelight distribution effectivenessVSAvoidfixture structure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent implements nesting by placing the light source inside the vessel containing liquid, with the vessel nested within the fixture housing. This nested arrangement allows light to pass through the liquid medium directly, creating effective light distribution while maintaining a compact and relatively simple overall structure that does not require complex external mounting mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The liquid within the vessel serves as an intermediary medium between the light source and the surrounding environment. The light source illuminates the liquid, and the liquid in turn distributes the light in unique patterns, mediating the light transmission process to achieve effective illumination without requiring complex optical systems or multiple components.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a vessel with liquid is incorporated into the light fixture, then unique and efficient lighting effects are achieved, but the device complexity increases

Engineering Contradiction:
Improvelighting effect versatilityVSAvoidfixture structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The vessel containing liquid serves multiple functions simultaneously: it acts as a container for the liquid medium, a light distribution element, and an aesthetic component that creates unique lighting effects. This multi-functionality allows the fixture to achieve versatile lighting effects without proportionally increasing complexity, as a single component (the vessel) fulfills multiple roles in the system.

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

3Illumination intensity

If light passes through liquid in the vessel, then enhanced lighting effects are produced, but the risk of liquid leakage and electrical safety issues increases

Engineering Contradiction:
Improvelighting effect qualityVSAvoidsystem reliability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent extracts or separates the electrical components (light source, wiring, power supply) from the liquid-containing environment by mounting them in the housing above or outside the liquid level. The light source is positioned to illuminate the liquid without being in direct contact with it, thereby eliminating electrical safety hazards and leakage risks while still achieving enhanced lighting effects through the liquid medium.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A light fixture includes a light receiver, an electrically-powered light source coupled to the light receiver, and a vessel containing a liquid. The vessel is translucent such that the light from the light source radiates through the vessel. The vessel includes an outer wall and an inner wall that define an enclosed area that receives and contains the liquid. The inner wall defines an open area positioned radially inward from the enclosed area and the inner wall includes a top opening and a bottom opening such that the open area is a through-hole extending through the enclosed area. The vessel is configured such that light emitted from the light source passes through the liquid contained within the vessel.
