Solution Overview

Problem

Existing LED lamps lack the ability to adjust illumination range according to specific needs, leading to increased manufacturing and maintenance costs, as well as confusion in replacement and installation.

Innovation Solution

A zoom LED lamp design featuring a chip receiving cylinder, a chip fixing column, a lens receiving cylinder, and a fixing cylinder, which allows for adjustable irradiation range through a sliding mechanism facilitated by a radial positioning ring and elastic sealing ring, and limited by the chip fixing column's ears, enabling precise control over the illumination area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different LED lamps are replaced to adjust lighting range, then lighting range adjustment is achieved, but manufacturing cost and maintenance complexity increase

Engineering Contradiction:
Improvelighting range adjustmentVSAvoidmaintenance complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic zoom mechanism where the lens receiving cylinder can slide axially within the chip receiving cylinder, allowing continuous adjustment of the lighting range from wide-angle to narrow-beam modes. This dynamic structure eliminates the need to replace entire lamp units, resolving the contradiction by providing adaptability through a single adjustable device rather than multiple fixed lamps.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal lamp structure that can perform multiple lighting functions (wide-area illumination and focused spot lighting) through the adjustable lens position. The single lamp unit with zoom capability replaces the need for multiple specialized lamps, reducing maintenance complexity while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the lens receiving cylinder is freely movable, then adjustment flexibility is improved, but positioning stability deteriorates

Engineering Contradiction:
Improveadjustment flexibilityVSAvoidlens positioning stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent employs an elastic sealing ring that provides pre-compression force against the lens receiving cylinder. This elastic cushioning force maintains stable contact between the lens cylinder and the chip receiving cylinder, ensuring positioning stability while still allowing controlled axial movement for adjustment. The elastic force acts as a cushion that prevents loose positioning while enabling flexibility.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The elastic sealing ring serves as an intermediary element between the lens receiving cylinder and the chip receiving cylinder. It mediates the interaction by providing both the necessary friction for stable positioning and the compliance for smooth adjustment movement, resolving the contradiction between stability and flexibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the lens receiving cylinder is tightly fixed, then positioning stability is improved, but adjustment capability deteriorates

Engineering Contradiction:
Improvelens positioning stabilityVSAvoidzoom adjustment capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent creates a dynamic fixing system where the lens receiving cylinder can move axially within controlled limits. The elastic sealing ring provides a friction-based connection that is stable during operation but allows deliberate movement when force is applied. This dynamic characteristic enables the system to maintain stability while preserving zoom adjustment capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the friction parameter through the elastic sealing ring's contact pressure. The elastic force provides sufficient friction to prevent unintended movement (stability) but allows controlled movement when external force is applied (adjustment capability). By adjusting the contact pressure parameter, both stability and adaptability are achieved.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The zoom LED lamp effectively regulates the irradiation range by fixing the lens receiving cylinder in both radial and axial directions without external force, reducing friction and wear, and allowing for easy adjustment of the illumination area, thus addressing the limitations of prior LED lamps.

Implementation Method 1

an elastic sealing ring received in the receiving groove, the minimum inner diameter of the elastic sealing ring being smaller than the minimum inner diameter of the radial positioning ring; the elastic sealing ring abutting on the lens receiving cylinder

AI summary

A zoom LED lamp comprises a chip receiving cylinder, a chip fixing column, a lens receiving cylinder, and a fixing cylinder. The chip receiving cylinder comprises a radial positioning ring, a receiving groove, and an elastic sealing ring. The chip fixing column comprises a column body and at least two ears. The two ears are fixed in the chip receiving cylinder. The lens receiving cylinder comprises a lens cylinder and two openings respectively inserted into the two ears. The zoom LED lamp not only fixes the position of the lens cylinder in the radial direction, but also allows the elastic sealing ring to fix the position of the lens cylinder in the axial direction of the chip receiving cylinder when no external force is applied. In addition, the sliding path of the lens cylinder in the axial direction of the chip receiving cylinder can also be limited, so that the irradiation range of the zoom LED lamp can be regulated.
