Lamp Connecting Rod Damper for Stable Adjustment

Solution Overview

Problem

Current lamps used for desktop lighting, such as table lamps, suffer from unstable performance, short lifespan, and poor hand feel due to their rotating structural members like latch rotation shafts, disc-shaped rotation shafts, or gooseneck hoses, which lead to eye fatigue and an uncomfortable lighting environment.

Innovation Solution

A lighting lamp design featuring a connecting rod assembly with a damper installed between the first and second connecting rods, providing resistance to movement and allowing for smooth, continuous adjustment, with a hydraulic or spring-damper mechanism that ensures stable performance and long service life, while preventing the connecting rods from rotating parallel to each other to maintain a controlled angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional rotating structural members (latch rotation shafts, disc-shaped rotation shafts, or gooseneck hoses) are used in lamps, then the lamp can achieve position adjustment, but the performance becomes unstable, lifespan is short, and hand feel is poor

Engineering Contradiction:

Improveperformance stabilityVSAvoidhand feel

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical rotating structures (latch rotation shafts, disc-shaped rotation shafts, gooseneck hoses) with a damper-based mechanical system. The damper uses a piston-cylinder arrangement with fluid damping to control movement, substituting the problematic mechanical rotation mechanisms with a more reliable damping-based positioning system that provides smooth adjustment and stable performance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a damper as an intermediary component between the connecting rods. This damper acts as a mediator that controls the relative movement between rod sections, providing smooth damping force during adjustment and maintaining stable positioning without the need for traditional rotation shafts, thereby improving both reliability and operational quality.

Inventive Principle:

Principle #24Intermediary (Mediator)
