Solution Overview

Problem

In deformable slidable electronic devices, such as rollable devices, the arrangement of electronic components within housings that slide with respect to each other is challenging due to assembly tolerances and gaps, leading to performance degradation, particularly for components like speakers that experience sound leaks.

Innovation Solution

An electronic device design featuring a first housing with specific side surfaces, a second housing with a bendable member, and a flexible display, where components are positioned to avoid interference during sliding, using a bendable electrical connection to maintain functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple electronic components are arranged in a three-dimensional stacked configuration, then the integration density is improved, but the manufacturing precision and alignment accuracy become more difficult to maintain

Engineering Contradiction:
Improveintegration densityVSAvoidalignment accuracy
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent implements a stacked configuration where multiple electronic component arrangements are vertically nested on top of each other, with each arrangement containing components in specific three-dimensional positions. This nesting approach increases integration density while using through-substrate vias and precise patterning to maintain alignment accuracy across layers.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from traditional planar two-dimensional component arrangement to a three-dimensional stacked configuration, adding the vertical dimension for component placement. This dimensional change allows higher integration density while employing sophisticated via structures and multi-layer patterning to preserve manufacturing precision in the new spatial configuration.

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

2Productivity

If the number of manufacturing processes is reduced, then the productivity is improved, but the manufacturing precision deteriorates

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidalignment accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent combines multiple manufacturing operations into integrated process steps. Specifically, it merges the formation of through-substrate vias with the patterning of conductive interconnects, and integrates the stacking of multiple component arrangements with the formation of inter-layer connections. This merging reduces the total number of discrete manufacturing processes while maintaining alignment accuracy through synchronized patterning techniques.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary actions by pre-forming through-substrate vias and pre-establishing alignment markers before final component placement. The methodology includes preliminary patterning of conductive interconnects and pre-registration of stacked arrangements, which enables faster subsequent processing while ensuring precise final alignment and connection accuracy.

Inventive Principle:
