Optical Processing Turntable Dynamic Balance Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wavelength conversion modules, such as fluorescent wheels, suffer from structural unbalance due to unevenly distributed locking surfaces and wavelength conversion layers, leading to vibration, noise, and reduced service life.
Innovation Solution
The optical processing turntable and wavelength conversion module designs feature locking surfaces and adjustment rings on opposite sides of the substrate, balancing the center of mass and reducing structural vibration by symmetrically distributing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the locking surface is located on one side of the fluorescent wheel, then the structure is simple, but vibration and noise are generated due to structure unbalance
Solution Approach 1:
The patent applies asymmetry by strategically positioning the locking surface and fluorescent layer at different locations on the wheel, creating an intentional asymmetric mass distribution that achieves dynamic balance. The locking surface is located at a first position while the fluorescent layer is positioned at a second position, allowing the center of gravity to be optimized for balanced rotation despite the asymmetric component placement.
2Adaptability or versatility
If the fluorescent layer is disposed on the other side relative to the locking surface, then the design allows for functional separation, but the locking surface bears an arm of force with considerable distance affecting service life
Solution Approach 1:
The patent employs the anti-weight principle by positioning the fluorescent layer as a counterbalancing mass relative to the locking surface. The fluorescent layer acts as a counterweight that offsets the force arm created by the locking surface position, reducing the mechanical stress and moment on the locking surface and driver assembly, thereby extending service life while maintaining functional separation.
3Ease of manufacture
If a balance-corrected metal ring is provided on one side only, then the manufacturing process is simple, but structure unbalance persists causing vibration and noise
Solution Approach 1:
The patent merges multiple functions into the wheel structure itself: the wheel integrates the locking surface, the fluorescent layer positioned at a different location, and the balance correction features all in one component. This integration allows the wheel to achieve dynamic balance through its inherent mass distribution rather than relying on separate balance rings, eliminating vibration and noise while maintaining manufacturing simplicity.

AI summary
An optical processing turntable, a wavelength conversion module, and a projection apparatus are provided. The optical processing turntable includes a substrate and a driver assembly. The substrate has a fixing hole and a first side and a second side opposite to each other. The driver assembly passes through the fixing hole to be disposed on the substrate to drive the substrate to rotate. The driver assembly has two locking surfaces, where the two locking surfaces are respectively located on the first side and the second side of the substrate. In the projection apparatus using the optical processing turntable provided by the invention, noise generated by structural vibration may be effectively reduced, and a prolonged service life is provided.
