Oscillating Optical Unit Support for Stable Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses face challenges in increasing resolution without increasing pixel density, leading to decreased yield and higher manufacturing costs, and stability issues in optical path due to uneven glass plate support, resulting in decreased image quality.
Innovation Solution
An optical device with a support unit that includes a recessed arrangement portion and shaft portions with equal rigidity, allowing the optical unit to oscillate stably, and using adhesives or notches to secure the optical unit, ensuring uniform oscillation and reduced unnecessary vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the glass plate is fixed to the holding member, then the optical path can be shifted by oscillating the glass plate, but the rigidities of the support springs become different causing unstable oscillation
Solution Approach 1:
The invention introduces a support unit that separates the glass plate from the shaft portions through a recessed arrangement portion. This segmentation allows the glass plate to be supported at multiple points with equal rigidity, enabling stable oscillation while maintaining optical path shifting capability.
Solution Approach 2:
The support unit acts as an intermediary between the glass plate and the shaft portions. It includes a recessed arrangement portion that faces the side face of the glass plate, and shaft portions that support the support unit, thereby indirectly supporting the glass plate with equal rigidity and ensuring stable oscillation.
2Reliability
If the side face of the glass plate contacts the holding member, then the glass plate is securely held, but the rigidities of support elements become unequal causing unstable oscillation
Solution Approach 1:
The support unit segments the holding function from the oscillation support function. The recessed arrangement portion provides secure holding by facing the side face of the glass plate, while the shaft portions provide equal rigidity support, separating these functions to resolve the contradiction.
Solution Approach 2:
The recessed arrangement portion is specifically designed to face the side face of the glass plate at specific locations, providing localized secure holding while maintaining overall oscillation stability through equal rigidity support from the shaft portions.
