Solution Overview

Problem

Conventional lighting lamps, such as desk lamps, are limited to single-direction illumination as the position of the light source assembly relative to the lamp holder is fixed, failing to meet the multi-directional illumination requirements of users.

Innovation Solution

A lighting assembly comprising a light source assembly with a rotatable connection assembly, where the first and second electrical terminals are in plugging and running fit to supply power and allow for adjustable rotation of the light source assembly relative to the connection assembly, enabling 360-degree circular rotation and adjustment of the light exiting direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the light source assembly is fixed relative to the lamp holder, then the structure is simple and stable, but the illumination direction cannot be adjusted

Engineering Contradiction:

Improveillumination direction adjustmentVSAvoidconnection structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed connection between the light source assembly and lamp holder into a rotatable connection. The connection rod enables the light source assembly to rotate around a vertical axis while maintaining electrical connection through the sliding contact between the groove and sliding block, achieving dynamic adjustment of illumination direction.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection rod serves as an intermediary component between the lamp holder and light source assembly. It provides both mechanical support for rotation and electrical connection through the integrated groove and sliding block structure, mediating between the stationary lamp holder and the movable light source assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the light source assembly is made rotatable, then multi-directional illumination is achieved, but the electrical connection reliability may deteriorate

Engineering Contradiction:

Improverotation adjustment capabilityVSAvoidelectrical connection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The groove and sliding block structure acts as an intermediary mechanism that maintains reliable electrical connection during rotation. The sliding block moves within the groove while maintaining continuous contact, ensuring stable power supply to the light emitting units throughout the rotation range.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical rotary connectors with a sliding contact system. Instead of using complex rotary switches or slip rings, the groove and sliding block provide a simpler mechanical solution that maintains electrical connection through linear sliding motion during rotation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If multiple light emitting units are arranged to form larger illumination area, then the lighting coverage is improved, but the device complexity increases

Engineering Contradiction:

Improveillumination areaVSAvoidlight source assembly complexity

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the light source assembly into multiple independent light emitting units (first, second, third, and fourth light emitting units) arranged on the light source plate. Each unit can be independently positioned and connected, allowing flexible configuration to achieve larger illumination coverage while maintaining manageable complexity through modular design.

Inventive Principle:
