Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Projectors face challenges in accurately adjusting the rotation angle of optical components during shipping and maintenance due to miniaturization and vibration, requiring a simplified adjustment mechanism to maintain image quality.
Innovation Solution
An optical module design featuring a first frame with a guiding slot, a second frame rotatably connected to the first frame, and a pillar that swings through the guiding slot to drive the second frame and optical component to rotate, allowing for adjustments without additional tools, integrating adjustments on multiple axes for operational convenience and space savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional adjustment mechanism is used for optical components, then the adjustment can be performed with tools, but the operational convenience is reduced and the device complexity increases
Solution Approach 1:
The adjustment mechanism allows users to directly adjust the rotation angle of optical components by manually swinging the pillar along the guiding slot without requiring any additional tools. The pillar itself serves as the adjustment actuator, and the guiding slot provides the adjustment path, enabling self-service adjustment operation.
Solution Approach 2:
The pillar serves multiple functions: it acts as both the adjustment actuator and the positioning element, while the guiding slot serves as both the adjustment path guide and the structural connector between frames. This multi-functionality reduces the need for separate adjustment tools and mechanisms.
2Adaptability or versatility
If multiple separate adjustment mechanisms are used for different axes, then each axis can be adjusted independently, but the device complexity increases and space is consumed
Solution Approach 1:
The adjustment mechanisms for different axes are merged into a unified structure where the pillar and guiding slot system handles adjustments for both the first axis (rotation of second frame) and the second axis (rotation of first frame). This combining of adjustment functions into a single integrated mechanism reduces overall device complexity and saves internal space.
Solution Approach 2:
The guiding slot is designed with a specific spatial orientation and shape that enables the pillar to achieve adjustments in multiple dimensions through its swinging motion. The slot's geometry translates single-degree-of-freedom pillar movement into multi-axis adjustment capabilities.
3Volume of moving object
If the projector is miniaturized to meet market demands, then the device size is reduced, but the adjustment mechanism becomes more difficult to implement
Solution Approach 1:
The adjustment mechanism is segmented into modular components: the first frame with guiding slot, the second frame with rotation axis, and the pillar as the connecting adjustment element. This segmentation allows for compact arrangement and easy assembly, facilitating implementation in miniaturized projectors.
Solution Approach 2:
The guiding slot provides a flexible adjustment path that accommodates the pillar's swinging motion in a compact space. The slot's curved or angled geometry enables the pillar to achieve rotational adjustment without requiring large movement amplitudes, making the mechanism suitable for miniaturized designs.
