Solution Overview

Problem

Existing pressurizing devices for electronic elements on circuit boards or connectors apply unbalanced pressure, leading to poor electric contact in the central regions due to insufficient pressure distribution, especially for larger-sized components.

Innovation Solution

A pressurizing device with both peripheral and central pressurizing units is used, where the peripheral units apply pressure to the peripheral region and central units apply pressure to the central region of the pressurizing plate, ensuring balanced force distribution and improved contact between electronic elements and circuit boards or connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only peripheral pressurizing units are used, then the device complexity is reduced, but the contact force in the central region becomes insufficient

Engineering Contradiction:

Improvepressurizing unit configurationVSAvoidcontact force in central region

Core Design Contradiction:

Device complexityVSForce

Solution Approach 1:

The pressurizing device is segmented into multiple independent pressurizing units distributed at different locations (peripheral and central regions). Each unit independently applies pressure to its local area, allowing the central region to receive sufficient pressure while maintaining a relatively simple overall device structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the pressurizing plate are provided with different pressurizing units according to their specific needs. The central region, which requires greater contact force for reliable electrical connection, is equipped with dedicated central pressurizing units, while peripheral regions have peripheral pressurizing units, creating a non-uniform but optimized pressure distribution.

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If only peripheral pressurizing units are used, then the manufacturing cost is reduced, but the electrical connection reliability deteriorates

Engineering Contradiction:

Improvepressurizing device manufacturingVSAvoidelectrical connection reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The pressurizing device is divided into multiple independent pressurizing units that can be manufactured separately and assembled. This segmentation allows for standardized production of individual units while ensuring that the complete device provides reliable electrical connection through the combined effect of all units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device provides enhanced pressure application capability in the central region through dedicated central pressurizing units, ensuring reliable electrical connection for larger-sized electronic elements where central region contact is critical, while maintaining cost-effectiveness through the modular unit structure.

Inventive Principle:

Principle #3Local quality

3Area of stationary object

If larger-sized electronic elements are used, then the functional capability is improved, but the pressure uniformity deteriorates

Engineering Contradiction:

Improveelectronic element sizeVSAvoidpressure uniformity

Core Design Contradiction:

Area of stationary objectVSStress or pressure

Solution Approach 1:

The pressurizing plate with larger area is divided into multiple pressure application zones, each served by its own pressurizing unit. This segmentation allows each unit to effectively pressurize its local region, maintaining pressure uniformity across the entire large-area electronic element by distributing the pressurization task across multiple units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the large-area pressurizing plate are equipped with pressurizing units according to their specific requirements. Central pressurizing units provide focused pressure application to the central region, ensuring adequate contact pressure even for larger electronic elements, while the overall pressure distribution remains balanced.
