Solution Overview

Problem

Existing sealing structures for electronic devices, such as portable apparatuses, face challenges in miniaturization due to the thickness and width requirements of signal lines, cable cases, and O-rings, leading to increased housing thickness and complex sealing processes that hinder productivity and workability.

Innovation Solution

A sealing structure that uses a sealing member between housings with overlapping signal lines bonded by an adhesive material, allowing the signal lines to penetrate through the sealing member, which is integrated with the gasket to minimize dimensions and enhance air-tightness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cable case and O-ring are used to seal signal lines between housings, then sealing performance is improved, but housing thickness increases

Engineering Contradiction:
Improvesealing performanceVSAvoidhousing thickness
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent integrates the sealing function directly into the gasket material itself, merging the previously separate components (cable case, O-ring, and gasket) into a single integrated sealing structure. The gasket includes a sealing portion with an inner circumferential surface that directly contacts and seals the signal line, eliminating the need for additional cable cases and O-rings, thereby reducing housing thickness while maintaining sealing performance.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple signal lines are forced through a sealing structure, then functionality is improved, but the sealing structure becomes more complex

Engineering Contradiction:
Improvesignal line capacityVSAvoidsealing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gasket's sealing portion is designed with a universal structure that can accommodate multiple signal lines of different sizes and configurations. The inner circumferential surface of the sealing portion provides a flexible sealing interface that adapts to various signal line arrangements, allowing the same gasket design to seal one or multiple signal lines without requiring additional complex components or structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a cable case and O-ring configuration is used, then sealing is achieved, but the manufacturing process becomes more complex and productivity decreases

Engineering Contradiction:
Improvesealing effectivenessVSAvoidmanufacturing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines the sealing function into the gasket itself, eliminating the need for separate cable cases and O-rings. This integration simplifies the assembly process as the gasket can be directly installed between housings without requiring additional steps to attach separate sealing components, thereby reducing manufacturing complexity and improving productivity while maintaining effective sealing.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If signal lines are individually sealed with separate structures, then sealing reliability is improved, but the occupied width increases

Engineering Contradiction:
Improvesealing reliabilityVSAvoidoccupied width
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent merges the sealing function for multiple signal lines into a single integrated gasket structure. The sealing portion of the gasket provides a continuous sealing interface that simultaneously seals multiple signal lines within a compact width, eliminating the need for separate sealing structures for each signal line, thereby reducing the total occupied width while maintaining sealing reliability.

Inventive Principle:
Principle #5Merging (Combining)
