Solution Overview

Problem

Conventional outdoor projector lights with a fluttering effect suffer from pattern instability due to motor-induced vibrations, resulting in chaotic and disorderly pattern projection.

Innovation Solution

The outdoor projector light incorporates a rotation device with a gear-pressing plate and bi-convex lenses, which stabilizes the rotation base and projects umbrella-like patterns in an orderly, fluttering fashion by rotating bi-convex lenses to simulate an umbrella opening and closing effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a motor-driven rotary board with multiple lenses is used to create a fluttering effect, then dynamic movement and entertainment value are improved, but vibration and pattern instability occur

Engineering Contradiction:

Improvefluttering effectVSAvoidpattern stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the harmful vibration function from the rotation system by introducing a separate damping mechanism. The damping element is added specifically to counteract vibration without interfering with the rotational movement that creates the fluttering effect, thus separating the useful function (rotation) from the harmful function (vibration).

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The damping element acts as an intermediary between the rotary board and the projection system. It absorbs and dissipates vibration energy transmitted from the motor-driven rotation mechanism, preventing these vibrations from reaching the projection lenses and causing pattern instability, while allowing the rotational motion to continue undisturbed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If the rotary board rotates rapidly to enhance dynamic effect, then entertainment value is improved, but vibration and chaotic pattern movement increase

Engineering Contradiction:

Improverotation speedVSAvoidvibration

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful vibration generated by rapid rotation into a beneficial damping effect. The damping element is specifically designed to absorb the vibration energy produced at higher rotation speeds, transforming what would be a harmful chaotic effect into a controlled and stabilized projection output, while maintaining the entertaining dynamic movement.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If a simple rotation mechanism is used to reduce complexity, then device complexity is reduced, but vibration control and pattern stability are compromised

Engineering Contradiction:

Improvemechanism complexityVSAvoidpattern stability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies local quality by adding the damping element specifically at the critical location where vibration affects pattern stability - at the rotary board or its mounting structure. This localized addition provides vibration control precisely where needed without requiring complex system-wide modifications, thus maintaining overall mechanism simplicity while improving reliability.

Inventive Principle:

Principle #3Local quality

AI summary

An outdoor projector light includes an enclosure, a projection device and a rotation device mounted inside the enclosure. A support device is connected with the enclosure. A primary lighting unit and a secondary lighting unit with multiple secondary lamps thereon are mounted on the support frame. The rotation device has a motor, a gear-pressing plate, a rotation base and a lens-mounting disc with multiple lenses thereon. The rotation base is rotatably mounted to the projection device and abuts against the gear-pressing plate to ensure stable operation of the rotation base. The lens-mounting disc is mounted on the rotation base. The lenses are even multiples of the secondary lamps in number. When the rotation device rotates the lens-mounting disc, light emitted from the secondary lighting unit passes through the lenses to project an even number of patterns simulating open and closed states of an umbrella with variation of dynamic pattern movement.
