Solution Overview

Problem

Current electrical lighting systems require time-consuming and cumbersome methods for charging and replacing batteries, such as plugging-in, inserting batteries, or unscrewing components, which is particularly problematic for multiple lighting setups like hotels or restaurants, and lack aesthetic appeal and user convenience.

Innovation Solution

Electric lighting systems with removably couplable power devices that allow for easy recharging and replacement, featuring self-orienting magnetic connections and universal interconnectivity, enabling quick insertion and removal of power devices without the need for manual alignment or wiring, and allowing continuous use by swapping charged devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional plugging-in or battery insertion methods are used, then electrical connection is established, but setup time and user inconvenience increase significantly

Engineering Contradiction:

Improveease of chargingVSAvoidsetup time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The lighting system is divided into separate modular components: a lighting element and a power device that can be independently manufactured and coupled. This segmentation allows the power device to be easily attached and detached without affecting the lighting element, enabling quick setup and charging operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Traditional mechanical connection methods (plugging, unscrewing, manual battery insertion) are replaced with a magnetic coupling mechanism. The magnetic field-based attachment eliminates complex mechanical operations, allowing users to simply bring the power device near the lighting element for automatic magnetic attachment, significantly reducing setup time and improving ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Duration of action of moving object

If multiple lighting units are used to ensure continuous operation, then continuous lighting is achieved, but cost and device complexity increase

Engineering Contradiction:

Improvecontinuous lightingVSAvoidnumber of lighting units

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The power device can be easily detached when depleted and replaced with a charged unit, while the lighting element remains in place. This allows the system to maintain continuous operation by simply swapping the power device rather than replacing the entire lighting unit, reducing the number of components needed and lowering overall system complexity.

Inventive Principle:

Principle #34Discarding and recovering

Solution Approach 2:

The lighting element is designed with universal compatibility to work with multiple power devices. The standardized magnetic coupling interface allows any compatible power device to be attached to the lighting element, enabling flexibility and continuous operation without requiring specialized components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If fixed wiring is used for each lighting location, then electrical connection is stable, but aesthetic appeal is diminished and flexibility is reduced

Engineering Contradiction:

Improveelectrical connection stabilityVSAvoidaesthetic flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The power device is extracted from the lighting element, allowing the lighting element to be wire-free and aesthetically pleasing. The power device can be separately charged and attached only when needed, eliminating the need for fixed wiring at each location while maintaining stable electrical connection through the magnetic coupling mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)
