Solution Overview

Problem

Existing adjustable lamps face issues with cable damage and aesthetic concerns due to externally routed electrical wiring, which compromises both functionality and appearance.

Innovation Solution

A two-piece side wall design for the lamp, where the electrical cable is integrated within the side walls, ensuring kink-free routing and protection through guided domes and recesses, allowing for pivoting without damage and maintaining a clean exterior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the electrical cable is routed externally from the support unit to the light unit, then the cable routing is simple and easy to implement, but the cable is easily damaged from the outside and the appearance of the lamp is negatively affected

Engineering Contradiction:
Improvecable routing simplicityVSAvoidcable damage resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The electrical cable is nested within the side wall structure of the lamp. The side wall contains an integrated cable guide channel that houses the cable from the support unit to the light unit, protecting it from external damage while maintaining a clean appearance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The side wall acts as an intermediary structure that mediates between the support unit and the light unit. It provides a protected pathway for the cable through its integrated cable guide channel, shielding the cable from external factors while allowing the lamp to maintain its structural integrity and aesthetic appearance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the electrical cable is routed externally, then the cable routing is straightforward, but the appearance of the lamp is negatively affected

Engineering Contradiction:
Improvecable routing simplicityVSAvoidlamp appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The cable is nested within the side wall's cable guide channel, making it invisible from the outside. This integration ensures the lamp maintains a clean, aesthetic appearance without visible external wiring, while the cable routing remains straightforward through the integrated pathway.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If the side wall is designed as a single piece, then the structure is simpler, but the cable routing becomes complicated with kinks in pivoting positions

Engineering Contradiction:
Improveside wall structure simplicityVSAvoidcable routing integrity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The side wall is segmented into multiple sections with integrated cable guide channels in each segment. This segmentation allows the cable to be routed through dedicated pathways in each section, preventing kinks and ensuring smooth cable routing during pivoting while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the cable is integrated in the side wall, then the cable is protected and routing is optimized, but the side wall design becomes more complex

Engineering Contradiction:
Improvecable protectionVSAvoidside wall design complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cable guide channel is merged with the side wall structure itself, integrating the cable routing function into the existing structural element. This merging provides cable protection and optimized routing while minimizing additional complexity, as the cable channel is formed as part of the side wall rather than as a separate additive component.

Inventive Principle:
Principle #5Merging (Combining)
