Solution Overview

Problem

The challenge is to protect and improve the antenna patterns in electronic devices from damage due to high-temperature and high-pressure manufacturing processes and external impacts, while also allowing for modification of antenna patterns to adapt to changing environmental conditions and electronic element arrangements.

Innovation Solution

An antenna module is designed with a pattern protection structure that includes a first case with antenna protection parts and a second case covering the antenna pattern, utilizing a simple spring structure to prevent deformation and allow for easy modification of the antenna pattern, and providing waterproofing and dustproofing functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the antenna pattern is disposed in an injection-molded article, then the antenna can be integrated into the device structure, but the antenna pattern may be deformed due to high-temperature and high-pressure manufacturing processes or external impact

Engineering Contradiction:

Improveintegration of antenna into device structureVSAvoidantenna pattern deformation resistance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The device structure is divided into multiple cases: a first case that contains the antenna pattern and a second case that covers it. This segmentation allows the antenna to be protected within the first case while the second case provides additional protection, preventing deformation from manufacturing processes and external impacts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first case is designed with a structure that cushions and protects the antenna pattern before it is exposed to high-temperature and high-pressure manufacturing processes or external impacts. This pre-protection structure prevents deformation by absorbing or distributing the stress before it reaches the antenna pattern.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If the antenna is sealed after being disposed, then the antenna is protected from external damage, but it becomes almost impossible to change the antenna pattern

Engineering Contradiction:

Improveantenna protectionVSAvoidantenna pattern modifiability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The first case is designed with a removable or openable structure that allows the antenna pattern to be accessed, removed, or modified. This dynamic design enables the antenna to be changed when needed while maintaining protection when the case is closed, resolving the contradiction between protection and modifiability.

Inventive Principle:

Principle #15Dynamics

3Length of stationary object

If the electronic device is made thinner, then user satisfaction is improved, but the radio wave transmitting/receiving environment deteriorates

Engineering Contradiction:

Improvedevice thicknessVSAvoidradio wave transmitting/receiving environment

Core Design Contradiction:

Length of stationary objectVSReliability

Solution Approach 1:

The antenna protection structure utilizes the vertical dimension by stacking cases above and below the antenna pattern, rather than increasing horizontal dimensions. This allows thinning of the overall device while maintaining adequate protection space for the antenna in the vertical direction, preserving radio wave transmission quality.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
