Solution Overview

Problem

Conventional digital image capturing apparatuses have a complex structure with a high number of components, leading to increased manufacturing costs, low yield rates, and a higher probability of defects due to their complicated design.

Innovation Solution

A digital image capturing apparatus with a reduced number of components, where the charge-coupled device (CCD) and control components are directly mounted on a main printed circuit board (PCB), and the lens barrel is directly connected to the PCB, eliminating the need for a separate flexible printed circuit board (FPCB) and additional connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a separate FPCB and connector are used to mount the CCD, then the CCD can be connected to the main PCB, but the number of components increases and manufacturing complexity increases

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidnumber of components

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the CCD mounting function directly onto the main PCB by providing a mounting surface on the PCB itself, eliminating the need for separate FPCB and connector components. The CCD is directly mounted on the main PCB, integrating multiple functions into a single component structure.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If multiple separate components (FPCB, connector, CCD assembly) are used, then the CCD can be connected to the main PCB, but manufacturing costs increase

Engineering Contradiction:

Improvemanufacturing costVSAvoidcomponent structure

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the CCD mounting structure with the main PCB into a single integrated component, eliminating the need for separate FPCB and connector parts. This merging of functions reduces the total component count and associated manufacturing costs.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates unnecessary intermediate components (FPCB, connector) from the CCD mounting process, keeping only the essential main PCB with integrated mounting surface, thereby reducing manufacturing complexity and cost.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If a complicated structure with multiple components is used, then the CCD can be mounted and connected, but the yield rate decreases and defect probability increases

Engineering Contradiction:

Improvedefect rateVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the CCD mounting function directly into the main PCB structure, reducing the number of connection interfaces and assembly steps. This simplification reduces potential failure points and improves overall system reliability.

Inventive Principle:

Principle #5Merging (Combining)
