Solution Overview

Problem

Existing holding jigs for optical elements, such as those described in Patent document 1, suffer from 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 enabling easier operation, combined with a screw member and biasing member to secure the optical element without additional force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wing bolt with operating wings is used as a fixing mechanism, then the rotation of the first arm can be fixed, but a large space is required between holding jigs for operator access, reducing the number of jigs that can be used collectively

Engineering Contradiction:

Improveoperation of fixing mechanismVSAvoidnumber of holding jigs for collective treatment

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent removes the operating wings from the bolt structure, extracting the cumbersome manual gripping requirement. The simplified bolt head can be operated with minimal space, allowing holding jigs to be arranged closely together for collective deposition treatment without requiring operator hand access space.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical wing bolt system requiring manual gripping and turning with a simplified bolt mechanism that can be operated more compactly. This substitution reduces the operational space requirement while maintaining the fixing function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If multiple holding jigs are arranged closely for collective deposition treatment, then work efficiency improves, but operator access to wing bolt operating wings becomes impossible

Engineering Contradiction:

Improvework efficiency of deposition treatmentVSAvoidaccess to fixing mechanism

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The operating wings are extracted from the bolt design, eliminating the need for operator hand access. The simplified bolt mechanism can be operated from a distance or with minimal space, enabling multiple holding jigs to be arranged closely together for efficient collective treatment.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If a wing bolt mechanism is used, then the first arm rotation can be fixed reliably, but the structure becomes complex and requires more space

Engineering Contradiction:

Improvefixing of first arm rotationVSAvoidstructure of fixing mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex wing structure from the bolt, retaining only the essential threaded fixing function. This simplification reduces structural complexity while maintaining the reliability of the first arm rotation fixing through the threaded engagement.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of adding operating wings to enable fixing, the patent inverts the approach by removing unnecessary elements and relying on the fundamental threaded bolt mechanism, which is inherently reliable for fixing rotation while being structurally simple.

Inventive Principle:

Principle #13The other way round (Inversion)
