Rotation Projector Gear Assembly for Dynamic Pattern Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors project static patterns, causing visual fatigue and are unsuitable for cheerful occasions or parties due to the lack of a mechanism to rotate the film.
Innovation Solution
A rotation projector with a housing, projection device, and supporting device that includes a driver, drive gear, gear assembly, and film reel assembly, allowing the film to rotate and project dynamic patterns by engaging the drive gear with the gear assembly, powered by a power supply member and lighting member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional projector is used to project patterns, then clear static patterns can be projected, but visual fatigue occurs and it is unsuitable for cheerful occasions
Solution Approach 1:
The patent applies the dynamics principle by transforming the static film projection system into a dynamic one. A drive gear engages with a gear assembly to rotate the film reel assembly, causing the film to move continuously during projection. This dynamic motion of the film creates rotating projected patterns that eliminate visual fatigue and enhance suitability for cheerful occasions such as parties.
2Adaptability or versatility
If a rotation mechanism is added to make the film rotate, then dynamic rotating patterns can be projected, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical rotation mechanisms with a simplified gear-driven system. A drive gear mounted on a driving shaft engages with a gear assembly (including a rotary gear) to rotate the film reel assembly. This mechanical substitution uses standard gear components rather than complex motors or actuators, achieving film rotation while minimizing device complexity.
Solution Approach 2:
The drive gear serves multiple functions: it transmits rotational motion from the driver to rotate the film reel assembly, and simultaneously engages with the gear assembly to ensure synchronized rotation. This multi-functionality reduces the need for additional separate components, thereby reducing overall device complexity while achieving the desired dynamic projection capability.
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 rotation projector effectively projects dynamic patterns, reducing visual fatigue and making it suitable for use in cheerful occasions or parties by rotating the film in synchronization with the drive gear, providing an engaging and dynamic visual experience.
Implementation Method 1
The driver is mounted on the mounting support and electrically connected to the power supply member. The driving shaft protrudes from and is driven to rotate by the driver.
Implementation Method 2
The lighting member is mounted on the mounting support and electrically connected to the power supply member. The lighting member is powered to project light to go through the film reel assembly
Implementation Method 3
The drive gear is mounted on the driving shaft. The gear assembly is rotatably mounted on the mounting support and engages with the drive gear. The driver drives the drive gear and the gear assembly to rotate. The film reel assembly is rotated at the same time.
