Solution Overview

Problem

In electronic devices with multiple circuit boards connected via flexible flat cables (FFCs), the existing structure complicates the removal of FFCs from connectors due to the need to remove a shield that covers the entire circuit board, which is screwed in multiple locations.

Innovation Solution

An electronic device design where a removable connector shield is used, allowing easy removal of FFCs from connectors without requiring the removal of the entire circuit board shield, thereby simplifying the repair process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the circuit board is covered with a shield that covers the entire circuit board, then noise shielding performance is improved, but the complexity of removing the FFC from the connector is increased

Engineering Contradiction:
Improvenoise shielding performanceVSAvoidFFC removal complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The shield is divided into two separate parts: a circuit board shield that covers the circuit board and a connector shield that covers the connector. This segmentation allows the connector shield to be removed independently for FFC replacement while the circuit board shield remains in place, resolving the contradiction between maintaining noise shielding and enabling easy repair.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If the connector is covered with a shield that covers the entire circuit board, then noise shielding performance is improved, but the time required for maintenance and repairs is increased

Engineering Contradiction:
Improvenoise shielding performanceVSAvoidmaintenance and repair time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

By segmenting the shield into a circuit board shield and a connector shield, the connector shield can be quickly removed and reattached during maintenance. This eliminates the need to remove multiple screws securing the entire circuit board shield, significantly reducing maintenance time while preserving noise shielding performance.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If the connector is covered with a shield that covers the entire circuit board, then noise shielding performance is improved, but the device complexity is increased

Engineering Contradiction:
Improvenoise shielding performanceVSAvoidshield structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shield is segmented into two functional parts: a circuit board shield for noise shielding and a connector shield for localized connector protection and FFC access. This segmentation actually reduces overall device complexity by allowing independent access to the connector without compromising the circuit board shield structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector shield is positioned within or adjacent to the circuit board shield structure, creating a nested arrangement where the connector shield provides additional localized protection while the circuit board shield provides overall shielding. This nested structure optimizes space utilization and maintains compact design.

Inventive Principle:
Principle #7Nested doll (Nesting)
