Solution Overview

Problem

Conventional capsule type medical devices with cubic antennas suffer from dead space issues, which hinder efficient use of space and lead to deformation during handling, limiting automatic mounting and increasing manufacturing costs.

Innovation Solution

A capsule type medical device design featuring a substrate section with a single-layer or multi-layer substrate, an antenna conductor closely attached to the substrate, and a transmitting circuit arranged within the antenna conductor's area, reducing dead space and improving handling and manufacturing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cubic antenna is used in conventional capsule type medical devices, then the antenna can be manufactured, but dead space is created inside the antenna and deformation occurs during handling

Engineering Contradiction:

Improveantenna manufacturingVSAvoidantenna deformation

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The antenna conductor is merged with the substrate section by closely attaching it to the substrate surface, eliminating the dead space between separate antenna components and the substrate. This integration prevents deformation during handling while maintaining manufacturability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The antenna conductor is nested within or closely attached to the substrate section, utilizing the substrate structure to support the antenna. This nesting approach eliminates void spaces and stabilizes the antenna configuration during device assembly and handling.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Device complexity

If a cubic antenna is used, then the antenna structure can be formed, but dead space remains which hinders efficient space utilization

Engineering Contradiction:

Improveantenna structure formationVSAvoiddead space inside antenna

Core Design Contradiction:

Device complexityVSVolume of moving object

Solution Approach 1:

The antenna conductor is combined with the substrate section, eliminating the dead space that would otherwise exist between separate antenna components and the substrate. This merging approach maintains structural formation capability while removing unnecessary void volume.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If conventional antenna designs are used, then manufacturing is possible, but automatic mounting is limited and production costs increase

Engineering Contradiction:

Improveantenna assemblyVSAvoidautomatic mounting capability

Core Design Contradiction:

Ease of manufactureVSExtent of automation

Solution Approach 1:

The antenna conductor is integrated with the substrate section, creating a unified component that can be automatically mounted as a single unit. This integration enables automatic mounting operations while reducing production costs associated with separate antenna assembly steps.

Inventive Principle:

Principle #5Merging (Combining)
