Solution Overview

Problem

Laser oscillation devices transfer vibrations to optical units, causing errors in laser light paths and potentially damaging shutter units due to mechanical stress.

Innovation Solution

A connection unit with first and second connection parts, supported by the oscillation and shutter units respectively, is designed to separate and structurally correspond to each other, interrupting vibration transfer and distributing mechanical stress effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the oscillation unit and shutter unit are directly connected, then the structural integrity is improved, but vibration is transferred to the optical unit causing errors in laser light paths

Engineering Contradiction:

Improvestructural integrityVSAvoidlaser light path accuracy

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The connection unit is divided into a first connection part supported by the oscillation unit and a second connection part supported by the shutter unit, with the two parts separated from each other. This segmentation interrupts the vibration transfer path while maintaining structural connectivity, resolving the contradiction between structural integrity and vibration isolation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection unit acts as an intermediary element between the oscillation unit and shutter unit. By using a separated structure where one connection part covers the other, it mediates the connection while preventing direct vibration transmission, thus protecting the optical unit from vibration-induced errors.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the connection unit is rigid to ensure structural stability, then mechanical strength is improved, but mechanical stress is concentrated and may damage the shutter unit

Engineering Contradiction:

Improvemechanical strengthVSAvoidmechanical stress concentration

Core Design Contradiction:

StrengthVSStress or pressure

Solution Approach 1:

The connection unit is segmented into first and second connection parts that are separated and do not directly contact each other. This segmentation distributes mechanical stress across two independent support structures rather than concentrating it at a single connection point, reducing the risk of shutter unit damage while maintaining overall structural strength.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

One connection part covers at least a portion of the other connection part, creating a nested configuration. This nested structure provides structural stability and strength while the separated design prevents stress concentration, as each part is independently supported by its respective unit.

Inventive Principle:

Principle #7Nested doll (Nesting)
