Optical Lens Holding Jig With Lockable Arms to Prevent Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens holders apply varying forces to lens substrates of different sizes and shapes, leading to potential deformation or damage during immersion coating and heating treatment.
Innovation Solution
A holding jig with a base, multiple swingable and lockable arms, and a biasing mechanism that allows secure holding of optical elements without applying external force after locking, using a torsion spring and locking mechanism to stabilize the arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spring-biased swingable holding member is used to hold lens substrates of various sizes and shapes, then adaptability to different lens types is improved, but the applied force varies and may cause deformation or damage to the lens substrate
Solution Approach 1:
The holding member is configured to be movable between a first position (contacting the lens substrate) and a second position (retracted), allowing dynamic adjustment of the holding state. This enables the system to adapt to different lens sizes and shapes while preventing deformation by retracting the holding member when not needed
Solution Approach 2:
The biasing member (spring) that causes harmful deformation is removed from the system. Instead of continuously applying spring force to the lens substrate, the holding member is simply moved to positions where it contacts or does not contact the lens, eliminating the harmful continuous biasing force while maintaining the ability to hold various lens types
2Reliability
If a strong biasing force is applied to ensure stable holding of lens substrates, then holding stability is improved, but the risk of deformation or damage increases for large or thin lenses
Solution Approach 1:
The holding member transitions from a static spring-biased system to a dynamic movable system. By controlling the position of the holding member, the system can provide stable holding when needed (first position) and eliminate holding force when not needed (second position), preventing deformation of sensitive lenses
Solution Approach 2:
The system prevents harmful deformation by retracting the holding member before heating treatment or when holding large/thin lenses. This preliminary action of moving the holding member to the second position eliminates the risk of deformation before it can occur during subsequent processing steps

AI summary
A holding jig which is capable of holding any of optical elements of various shapes or sizes, and free of causing deformation or damage of the optical elements. A holding jig for holding an optical element includes: a base; first, second and third holding parts which hold the periphery of a lens substrate; a first arm to which the first holding part is attached and which is provided to the base swingably about a pivot; a torsion spring biasing the first arm in a first swinging direction such that the first holding part is urged toward the lens substrate; and an arm locking mechanism configured to lock the swinging of the first arm.
