Solution Overview

Problem

Existing circuit modules have limited space for mounting electronic components, which restricts the expansion of the component mounting region.

Innovation Solution

A module design featuring a substrate with a first metal member having a plate-shaped portion and support portions bent to extend behind the plate-shaped portion, allowing for a wider mounting region by eliminating protrusions that restrict component placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a conventional conductive partition structure is used, then electromagnetic interference is suppressed, but the component mounting region is limited

Engineering Contradiction:
Improvecomponent mounting regionVSAvoidelectromagnetic interference
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The conductive partition is divided into multiple separate partitions instead of using a single continuous structure. This segmentation allows the partitions to be arranged in a specific pattern that provides both EMI shielding and creates usable mounting spaces between them, thus resolving the contradiction between limiting EMI and providing mounting area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conductive partitions extend not only in the planar direction but also protrude in the vertical direction from the substrate surface. This three-dimensional arrangement creates regions between the protruding partitions where components can be mounted, effectively increasing the mounting region while maintaining EMI suppression functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If the conductive partition extends in multiple directions, then EMI shielding is improved, but the structure becomes complex

Engineering Contradiction:
Improveelectromagnetic interferenceVSAvoidpartition structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Multiple conductive partitions are merged into a single integrated conductive plate structure. The partitions are formed by cutting and folding a single continuous metal plate, which simplifies manufacturing compared to assembling multiple separate components, while still achieving the desired complex three-dimensional shielding configuration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conductive partition structure incorporates bent and folded portions that create dynamic spatial arrangements. These folds allow the partition to extend in multiple directions and create three-dimensional shielding regions without requiring complex assembly, as the shape is formed in a single manufacturing process.

Inventive Principle:
Principle #15Dynamics

AI summary

A module includes a substrate and a first metal member. The substrate has an upper main surface and a lower main surface arranged in an up-down direction. The first metal member includes a first plate-shaped portion provided on the upper main surface of the substrate, and includes a front main surface and a back main surface arranged in a front-back direction when viewed in an up-down direction. The first metal member further includes a first left support portion. A boundary between the first plate-shaped portion and the first left support portion is defined as a first left boundary. The first left support portion bends with respect to the first plate-shaped portion at the first left boundary so as to be located behind the first plate-shaped portion.
