Solution Overview

Problem

Electronic devices face challenges in securing design space for guiding electronic component arrangement due to the trend towards slim form factors and the need to accommodate various components in limited spaces.

Innovation Solution

An electronic device incorporating a printed circuit board with components on both surfaces, and a metal structure that shields electromagnetic interference (EMI) by covering part of one component and extending through the board to support another component, thereby guiding the arrangement position without additional members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a separate guiding structure is added to guide electronic component arrangement, then the component arrangement precision is improved, but the device complexity and space occupation increase

Engineering Contradiction:

Improvecomponent arrangement precisionVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines the electromagnetic shielding function and the component guiding function into a single integrated structure. The shielding plate includes protrusions that extend toward the circuit board, which serve dual purposes: providing EMI shielding and guiding the arrangement position of electronic components. This eliminates the need for separate guiding structures, thereby reducing device complexity while maintaining manufacturing precision.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shielding plate is designed to perform multiple functions simultaneously: electromagnetic interference shielding, component arrangement guiding, and structural support. The protrusions on the shielding plate create designated spaces that guide component placement while the plate itself provides EMI protection. This multi-functionality reduces the overall number of components needed in the device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If various electronic components are disposed in limited space to achieve slim form factor, then the device volume is reduced, but the manufacturing precision and component arrangement difficulty worsen

Engineering Contradiction:

Improvedevice volumeVSAvoidcomponent arrangement precision

Core Design Contradiction:

Volume of moving objectVSManufacturing precision

Solution Approach 1:

The shielding plate features localized protrusions at specific positions that create precise guiding structures for component placement. These protrusions provide local geometric constraints that ensure accurate component arrangement in the limited space available. The localized guiding features enable precise component positioning without requiring the entire device to be larger.

Inventive Principle:

Principle #3Local quality

3Manufacturing precision

If additional guiding members are added to guide component arrangement, then the component arrangement precision is improved, but the device cost increases

Engineering Contradiction:

Improvecomponent arrangement precisionVSAvoidmanufacturing cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent integrates the guiding function into the existing shielding plate structure through protrusions, eliminating the need for separate guiding members. This integration reduces the total number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining component arrangement precision.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shielding plate serves multiple functions including EMI shielding and component guiding, which would otherwise require separate components. By making the shielding plate multi-functional, the patent reduces the bill of materials and assembly complexity, leading to lower manufacturing costs without sacrificing precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)
