Optical Module Bracket Assembly for Projector Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of projectors complicates the assembly of their components, requiring multiple jigs and increasing labor and costs, while cumulative errors lead to decreased yield.
Innovation Solution
The optical module is designed with a modularized structure where the driving component, optical component, and light guide element share a single bracket, simplifying assembly and eliminating the need for multiple fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components are miniaturized to reduce projector size, then the projector volume is reduced, but the assembly complexity increases and requires multiple jigs
Solution Approach 1:
The patent integrates multiple optical components (light guide element, optical component, driving component) onto a single bracket, creating a modular assembly unit. This merging of components reduces the number of separate assembly operations required and eliminates the need for multiple jigs, thereby reducing assembly complexity while maintaining miniaturization benefits
2Adaptability or versatility
If multiple components are sequentially assembled, then the projector functionality is achieved, but cumulative errors increase and yield decreases
Solution Approach 1:
By pre-assembling multiple optical components onto a single bracket as an integrated module, the patent reduces the number of sequential assembly steps. This modular approach minimizes cumulative positioning errors that would occur with multiple separate assembly operations, thereby improving manufacturing precision and yield while maintaining full projector functionality
3Reliability
If multiple jigs are used for component assembly, then assembly completeness is ensured, but labor costs and assembly time increase
Solution Approach 1:
The patent consolidates multiple components into a single modular assembly unit mounted on one bracket. This integration allows the entire optical assembly to be installed as one unit using a single jig, thereby maintaining assembly completeness and reliability while significantly reducing labor costs and assembly time compared to assembling multiple separate components

AI summary
An optical module and a projector having the optical module are provided. The optical module includes a bracket, a driving component, an optical component, and a light guide element. The optical component is movably disposed on the bracket and is located on a transmission path of an image beam. The driving component is disposed between the bracket and the optical component and is configured to drive the optical component to oscillate. The light guide element is disposed at the bracket and located on the transmission path of the image beam. Here, the assembly of the optical module and the projector is easy, and the assembly yield is high.
