Solution Overview

Problem

Existing pitch conversion devices face challenges in accurately aligning multiple entry members between substrate holding members due to dimensional tolerances, leading to positional misalignment and over-sizing issues, particularly in ensuring simultaneous entry and avoiding interference post-process.

Innovation Solution

A pitch conversion device with parallel plate-shaped members and entry members, utilizing an extrusion or pushing member to sequentially push entry members between neighboring members, eliminating the need for varying heights and incorporating a sensor to ensure accurate alignment and prevent interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple entry members enter between adjacent substrate holding members simultaneously, then the pitch conversion can be completed in one operation, but the positional misalignment increases due to cumulative dimensional tolerances of all substrate holding members

Engineering Contradiction:
Improvepitch conversion operation efficiencyVSAvoidpositional alignment accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent divides the simultaneous entry action into sequential segments. Entry members enter between substrate holding members one after another in order, rather than simultaneously. This segmentation allows each entry member to be positioned accurately relative to its target substrate holding members without the cumulative tolerance errors that would result from attempting simultaneous entry of multiple members.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If entry members are arranged at different heights to enable sequential entry, then the positional misalignment is reduced, but the device size increases

Engineering Contradiction:
Improvepositional alignment accuracyVSAvoiddevice compactness
Core Design Contradiction:
Manufacturing precisionVSShape

Solution Approach 1:

The patent employs a movable pushing member that dynamically changes position to enable sequential entry of entry members at the same height. The pushing member moves along the array of entry members, pushing each one into position between the substrate holding members in turn. This dynamic mechanism allows sequential operation without requiring different heights for entry members, thereby maintaining device compactness while achieving accurate positioning.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If a pushing member is used to sequentially push entry members between substrate holding members, then the positional alignment is improved and device size is reduced, but the mechanism complexity increases

Engineering Contradiction:
Improvepositional alignment accuracyVSAvoidmechanism structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The pushing member serves multiple functions: it pushes each entry member sequentially into position between substrate holding members, and after all entry members are in position, it pushes all entry members simultaneously to their final positions. This multi-functionality reduces the need for additional specialized mechanisms, thereby limiting the increase in overall device complexity while achieving the desired sequential operation and compact design.

Inventive Principle:
Principle #6Universality (Multi-functionality)
