Solution Overview

Problem

Traditional double lampshade table lamps have a complex structure with multiple pivot shafts and screw connections, making them inconvenient to use and increasing manufacturing time and cost.

Innovation Solution

A flexible pole with two lampshade assemblies that pivotally couple to a coaxial shaft seat, featuring vertically staggered bushings for easy assembly and adjustment, allowing for focused or fan-shaped lighting distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If three pivot shafts are arranged in a triangular shape to connect lampshade assemblies, then the lampshade assemblies can be pivotally connected, but the structure becomes complex and manufacturing time increases

Engineering Contradiction:

Improvepivotal connection reliabilityVSAvoidpivot joint structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines three separate pivot shafts into a single integrated shaft seat with coaxial installation. The shaft seat includes a limiting disk and limiting seat that together provide the pivotal connection function, eliminating the need for multiple separate shafts and their associated screw connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shaft seat serves multiple functions simultaneously: it acts as the pivot axis for lampshade assemblies, provides limiting functions through the limiting disk and limiting seat, and enables coaxial installation. This multi-functional design replaces the need for multiple specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple screw connections and alignments are required for assembling pivot shafts, then the pivot joint can be assembled, but manufacturing time and cost increase

Engineering Contradiction:

Improvepivot joint assembly reliabilityVSAvoidassembly speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent merges multiple assembly operations into a single integrated component. The shaft seat is designed as one piece that includes the pivot axis, limiting disk, and limiting seat, eliminating the need for multiple separate assembly steps and screw connections.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The limiting disk and limiting seat are pre-integrated into the shaft seat structure during manufacturing. This preliminary action ensures proper alignment and positioning are built into the component itself, eliminating the need for field alignment and multiple screw connections during assembly.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the pole has no bending angle, then the structure remains simple, but the lighting angle cannot be adjusted

Engineering Contradiction:

Improvepole structure simplicityVSAvoidlighting angle adjustability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a flexible pole that can be bent to different angles while maintaining structural integrity. This dynamic capability allows the pole to adapt to different lighting requirements without requiring a completely different structure for each angle.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pole's physical state is changed from rigid to flexible, allowing it to be bent to various angles. This parameter change enables the same simple pole structure to provide multiple lighting angles by simply changing its bending state rather than its fundamental structure.

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If two lampshade assemblies are used to provide lighting for multiple users, then the lighting coverage increases, but the structure becomes more complex

Engineering Contradiction:

Improvelighting coverage areaVSAvoidlampshade assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shaft seat is designed to support multiple lampshade assemblies simultaneously through coaxial installation. This universal design allows the same shaft seat structure to accommodate two or more lampshade assemblies, providing extended lighting coverage without proportionally increasing structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A double lampshade table lamp includes a base, a flexible pole vertically erected from the top of the base, and two lampshade assembly horizontally pivoted to the top of the pole and each having a light tube. The flexible pole can be bent to change the angle of the two lampshade assemblies, and the rear ends of the two lampshade assemblies respectively have bushings which are in a vertical staggered relation to each other and pivoted to the top of the pole, so that the two lampshade assemblies are situated at the same height and can be deflected to provide concentrated and focused light and a fan-shaped expansion of the lighting area.
