Solution Overview

Problem

The aesthetic value of magnetic suspension lamps is limited due to uneven lighting on closed-shaped lampshades, as the light from a luminescent lamp below cannot illuminate the lampshade evenly, restricting the shape and structure of the lampshade.

Innovation Solution

A self-luminous suspension lamp with a floater containing a light-emitting device and a magnet, balanced by a magnetic force from an electromagnetic coil, using a Hall sensor for real-time feedback to maintain optimal suspension and a wireless charging system to power the LED light, allowing even illumination and various shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a luminescent lamp is placed below the lampshade to illuminate it, then the lamp can be suspended without electric wires, but the light cannot illuminate the lampshade evenly when the lampshade is a closed shape

Engineering Contradiction:
Improvewireless suspensionVSAvoiduniformity of illumination
Core Design Contradiction:
Ease of operationVSIllumination intensity

Solution Approach 1:

The patent replaces the traditional mechanical wiring system with a magnetic field-based wireless power transmission system. Electromagnetic coils in the base generate magnetic fields that induce currents in coils within the lampshade, providing power wirelessly while maintaining suspension through magnetic repulsion between the base electromagnet and the lampshade magnet.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent integrates multiple functions into the electromagnetic coils: one coil serves for wireless power transmission while another coil (or the same coil at different times) serves for magnetic suspension. This multi-functionality resolves the contradiction by enabling both wireless operation and uniform illumination through integrated electromagnetic field control.

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

2Shape

If the lampshade is made as a closed shape for aesthetic purposes, then the overall appearance is improved, but the light from the luminescent lamp cannot illuminate the lampshade evenly

Engineering Contradiction:
Improveaesthetic valueVSAvoiduniformity of illumination
Core Design Contradiction:
ShapeVSIllumination intensity

Solution Approach 1:

The patent replaces traditional bulb-based illumination with LED light sources that can be integrated directly into the lampshade structure. These LEDs are powered wirelessly through electromagnetic induction, enabling uniform distribution of light sources across the closed lampshade surface, thereby achieving even illumination while maintaining aesthetic closed shapes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent divides the illumination function into multiple distributed LED sources throughout the lampshade rather than using a single luminescent lamp below. This segmentation allows each segment to illuminate its local area uniformly, and collectively they provide even overall illumination across the closed lampshade surface.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If magnetic suspension technology is applied to the lamp to improve ornamental value and motion value, then the lamp achieves wireless suspension, but the light illumination remains uneven on closed-shaped lampshades
