Solution Overview

Problem

The assembly of flexible circuit boards in camera modules is challenging due to the need for precise alignment of connectors with printed circuit board terminals, which can lead to misalignment and damage during assembly.

Innovation Solution

A camera module assembly design that includes a support member with a guide part to maintain the flexible circuit board in a bent state, facilitating easy alignment and connection with the printed circuit board terminal without changing the connector's location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible circuit board is allowed to move freely during assembly, then the connector location can adapt to bending shapes, but misalignment and damage occur during connector assembly

Engineering Contradiction:

Improveconnector location adaptabilityVSAvoidassembly reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The support member maintains the flexible circuit board in a predetermined bent state before assembly, so that the connector is pre-positioned at the correct location for alignment with the connection terminal, preventing misalignment and damage during assembly

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The support member acts as an intermediary device between the flexible circuit board and the assembly process, providing mechanical support and maintaining the board in a specific bent configuration that ensures proper connector positioning

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If the flexible circuit board is maintained in a bent state, then connector alignment with terminal is improved, but the board requires additional support structure

Engineering Contradiction:

Improveconnector alignment precisionVSAvoidsupport structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The support member serves multiple functions: it maintains the flexible circuit board in a bent state for proper connector alignment, provides structural support during assembly, and guides the positioning of the connector relative to the connection terminal, thereby achieving precise alignment without requiring complex additional structures

Inventive Principle:

Principle #6Universality (Multi-functionality)
