Solution Overview

Problem

Conventional multi-axis operation apparatuses face challenges in achieving higher operational accuracy due to alignment tolerances between working mechanisms, which typically rely on one mechanism as a fixed reference for alignment.

Innovation Solution

A multi-axis operation apparatus with a first and second operation mechanism, each comprising a rail and a movable platform, and an indicator with calibrations that serve as a fixed alignment reference, allowing precise positioning through sensors and calibrations to reduce alignment distances and tolerances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If one working mechanism is used as a fixed reference for alignment, then the alignment process is simplified, but alignment tolerance increases and operational accuracy decreases

Engineering Contradiction:
Improvealignment process complexityVSAvoidalignment accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent introduces an indicator as an intermediary component positioned between the first and second operation mechanisms. This indicator includes calibrations that serve as a common reference for both mechanisms, eliminating the need to use one mechanism as the reference. The indicator mediates the alignment process by providing a separate, dedicated reference structure that both mechanisms can align to, thereby reducing alignment tolerance while keeping the alignment process simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If alignment reference is placed far from operation mechanisms, then accessibility is improved, but alignment tolerance increases due to larger distances

Engineering Contradiction:
Improveaccessibility of alignment referenceVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent positions the indicator in a spatial arrangement that optimizes both accessibility and alignment precision. By placing the indicator between the two operation mechanisms rather than far from them, and by using calibrations that can be accessed from multiple directions, the solution creates a multi-dimensional alignment reference system. This allows the calibrations to be accessible for alignment purposes while maintaining short distances that minimize alignment tolerance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If distance between operation mechanisms and alignment reference is increased, then space for operation is improved, but tolerance accumulates over longer distances

Engineering Contradiction:
Improveoperational spaceVSAvoidcumulative alignment tolerance
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent segments the alignment reference into multiple calibrations distributed on the indicator structure. Instead of using a single distant reference point, the alignment system is divided into multiple local reference points (calibrations) that are positioned on the indicator between the operation mechanisms. This segmentation allows each mechanism to align to its nearest calibration, minimizing the distance and thus the tolerance, while still providing sufficient operational space.

Inventive Principle:
Principle #1Segmentation

AI summary

A multi-axis operation apparatus in opposite arrangement includes a first operation mechanism, a second operation mechanism spaced apart from the first operation mechanism, and an indicator that is located between the first operation mechanism and the second operation mechanism. The first operation mechanism includes a first rail and a carrying platform that is assembled to the first rail. The second operation mechanism includes a second rail and a working member that is assembled to the second rail. The indicator includes a carrier, a first calibration, and a second calibration, the latter two of which are arranged on the carrier. The carrying platform and the working member respectively face toward the first calibration and the second calibration for obtaining current positions thereof, thereby allowing the working member to perform a predetermined step to a target object on the carrying platform through a window of the carrier.
