Solution Overview

Problem

The stability of the electrical connection between the charging unit and the power feeding unit in blood pressure measurement devices is compromised due to the curved shape of the curler, which makes it difficult to maintain a secure connection.

Innovation Solution

A blood pressure measurement device charging connector with a clip mechanism, including a first and second member, a rotational shaft, and a biasing member, that securely attaches to the cuff of the curler, using a protrusion to support the cuff's inner surface and prevent rotation, ensuring stable connection to the power feeding terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the connector is attached to the curved curler to fit the wrist, then the device can be worn on the wrist, but the connector posture becomes unstable and electrical connection cannot be maintained

Engineering Contradiction:

Improvewrist mounting capabilityVSAvoidconnector electrical connection stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The connector incorporates a flexible clip structure with first and second members that can elastically deform to conform to the curved surface of the curler while maintaining stable electrical contact. The biasing member provides continuous contact force through the flexible structure, ensuring reliable connection despite the curved geometry.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The connector uses a dynamic clip mechanism with rotational freedom around a rotational shaft, allowing the connector to adapt its posture to the curved curler surface while maintaining electrical connection. The biasing member dynamically adjusts the contact force between the connector and power feeding terminal.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If the connector is made rigid to maintain stable connection, then electrical connection can be maintained, but the connector cannot adapt to the curved shape of the curler

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connector is divided into multiple segments including a first member, a second member, and a rotational shaft, allowing each segment to move independently. This segmentation enables the connector to conform to curved surfaces while maintaining stable electrical connection through the coordinated movement of segments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector employs flexible structural elements that can bend and deform to match the curved geometry of the curler, while the biasing member ensures continuous contact pressure is maintained for stable electrical connection.

Inventive Principle:

3Adaptability or versatility

If the connector allows rotation to adapt to different positions, then it can fit the curved wrist, but the electrical connection becomes unstable

Engineering Contradiction:

Improveposition adjustment capabilityVSAvoidelectrical connection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The connector incorporates a rotational shaft that allows controlled rotation to adapt to different positions on the curved wrist, while the biasing member maintains constant contact force between the connector and power feeding terminal, ensuring reliable electrical connection throughout the range of motion.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flexible clip structure with biasing member allows the connector to rotate and adapt to different positions while maintaining stable electrical contact through continuous elastic contact force.

Inventive Principle:
