Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding jigs for optical elements, such as those described in Patent document 1, face inefficiencies in collective deposition treatments due to the need for large operational spaces and cumbersome wing bolt mechanisms, leading to reduced work efficiency.
Innovation Solution
A holding jig design featuring a lever mechanism that allows for parallel rotation to fix the first holding mechanism, reducing the need for space and simplifying operations, combined with a screw member and biasing member to securely hold optical elements without additional force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wing bolt fixing mechanism is used to fix the rotation of the first arm, then the holding mechanism can be securely fixed, but the space required between adjacent holding jigs increases, reducing the number of jigs that can be used for collective deposition treatment
Solution Approach 1:
The fixing mechanism is segmented into two independent functions: a wing bolt for securing the holding mechanism to the base, and a separate lever for fixing the rotation of the first arm. This segmentation allows the lever to be positioned without interfering with adjacent jigs, enabling collective deposition treatment of multiple jigs while maintaining secure fixing reliability.
Solution Approach 2:
The lever for fixing the first arm rotation is positioned in a different spatial dimension (parallel to the plane containing the rotation direction) rather than extending in the direction between adjacent jigs. This dimensional change allows the lever to operate without interfering with neighboring holding jigs, increasing the number of jigs that can be collectively treated.
2Reliability
If a wing bolt mechanism is used for fixing the rotation of the first arm, then the holding mechanism can be securely fixed, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The fixing mechanism is divided into two separate components with distinct functions: the wing bolt secures the holding mechanism to the base, while the lever specifically fixes the rotation of the first arm. This segmentation simplifies the operation for fixing the first arm rotation, as the lever can be quickly operated without the complexity of a wing bolt mechanism.
Solution Approach 2:
Instead of using a wing bolt (which requires two-handed operation and complex tightening motions) for fixing the first arm rotation, a lever mechanism is employed. The lever can be operated with one hand through simple rotational motion, inverting the conventional approach and significantly improving ease of operation.
3Productivity
If multiple holding jigs are arranged closely for collective deposition treatment, then work efficiency improves, but the operator cannot access the wing bolt for operation due to space constraints
Solution Approach 1:
The lever for fixing the first arm rotation is positioned parallel to the plane containing the rotation direction, rather than extending in the direction between adjacent jigs. This dimensional repositioning allows the lever to be accessed and operated even when multiple jigs are closely arranged for collective deposition treatment, maintaining both productivity and ease of operation.
Solution Approach 2:
By segmenting the fixing mechanism into a wing bolt (for securing to the base) and a separate lever (for fixing first arm rotation), the lever can be positioned in a location that is accessible when jigs are closely arranged, while the wing bolt remains secured. This segmentation enables close arrangement of multiple jigs for efficient collective treatment without compromising operational accessibility.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves work efficiency by allowing multiple jigs to be used collectively without interference and simplifying the operation of fixing the holding mechanisms, enhancing productivity and stability during deposition treatments.
Implementation Method 1
a biasing member that biases a first holding mechanism among the plurality of holding mechanisms so that the first holding mechanism rotates toward a side surface of the optical element to be held
Implementation Method 2
a screw member inserted through at least the base, the first holding mechanism, and the lever, and that is screwed into at least any of the lever, the base, and the first holding mechanism

AI summary
There are provided a holding jig 1 and a related technique thereof, which is a holding jig 1 for holding an optical element, including: a base; a plurality of holding mechanisms that hold a peripheral edge of the optical element; a biasing member that biases a first holding mechanism 15 among the plurality of holding mechanisms so that the first holding mechanism 15 rotates toward a side surface of the optical element to be held; and a lever 90 that can be rotated in a direction parallel to a plane including a rotation direction of the first holding mechanism 15, wherein the lever 90 is rotated to fix the first holding mechanism 15, thereby reducing a biasing force added on the optical element by the biasing member.
