Solution Overview

Problem

Existing power supply devices for intracorporeal implant-type medical appliances face challenges in performing puncturing operations while supplying electric power non-contactually, as they require close proximity to the medical appliance, making it difficult to manage the insertion of an injection needle simultaneously.

Innovation Solution

A power supply device with a non-contact power transmission coil, a support body, an adhesive section, and an elastic deformation section that allows for easy puncturing and power supply to the medical appliance, featuring a design that includes a hole for the injection needle and a spiral power transmission coil for efficient power transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the power supply device is held close to the medical appliance for non-contact power supply, then power transmission efficiency is improved, but the ease of performing puncturing operation deteriorates

Engineering Contradiction:
Improvepower transmission efficiencyVSAvoidease of performing puncturing operation
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The power supply device is segmented into a power supply unit and a separate adhesive patch unit. The adhesive patch can be applied to the skin surface and remains in place during puncturing operations, while the power supply unit can be moved closer for efficient power transmission without requiring the user to hold the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adhesive patch acts as an intermediary between the power supply device and the medical appliance. It maintains the positional relationship and enables power transmission through the skin while allowing free movement of the power supply unit during puncturing operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the power supply device is designed with a fixed structure for stable power transmission, then power supply reliability is improved, but the adaptability to body surface contours deteriorates

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidadaptability to body surface contours
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The adhesive patch is designed as a flexible thin film structure that can conform to the contours of the body surface. This flexible structure maintains reliable electrical connections for power transmission while adapting to various skin shapes and movements.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The adhesive patch incorporates dynamic elements that allow it to flex and move with the body surface. This enables the power transmission components to maintain stable connections while the overall structure adapts to changing body contours during movement.

Inventive Principle:
Principle #15Dynamics

AI summary

A power supply device includes a power transmission coil which supplies electric power from outside the body in a non-contact manner via a power reception coil of an intracorporeal implanting-type medical appliance to which a drug solution is injected from outside the body. A support supports the power transmission coil, and an adhesive part is formed on the side of the support facing the body surface of a living subject.
