Optical Scanning Device Vibration Attenuation via Elastic Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical scanning devices face issues with vibration attenuation, leading to disturbance vibrations that affect scan accuracy and increase cost and size, as the conventional vibration attenuating members are inadequate and inefficient.
Innovation Solution
The optical scanning device incorporates a first bonding and vibration attenuating unit, which uses an elastic member to bond the vibration unit to the optical waveguide, effectively absorbing disturbance vibrations and improving scanning precision while reducing device size and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vibration attenuating member is used to cover the optical fiber, then some vibration attenuation is provided, but the device size and cost increase significantly while vibration attenuation performance remains inadequate
Solution Approach 1:
The patent combines the bonding function and vibration attenuation function into a single integrated unit. The bonding agent simultaneously bonds the vibration generating unit to the optical waveguide and attenuates disturbance vibrations, eliminating the need for separate vibration attenuating members and reducing device complexity while maintaining effective vibration attenuation
Solution Approach 2:
The bonding agent serves multiple functions: it provides mechanical bonding between components and simultaneously acts as a vibration attenuating element. This multi-functional approach replaces conventional single-function vibration attenuating members, achieving both bonding and vibration attenuation without increasing device size or cost
2Device complexity
If disturbance vibrations are not adequately attenuated, then device size and cost are reduced, but scan accuracy deteriorates due to propagated vibrations affecting the optical waveguide
Solution Approach 1:
The patent applies vibration attenuation properties locally at the bonding interface between the vibration generating unit and optical waveguide. By positioning the vibration attenuating function exactly where disturbance vibrations are generated and transmitted, the system effectively protects scan accuracy without requiring comprehensive vibration attenuation throughout the entire device structure
