Solution Overview

Problem

Blood pressure cuffs with ring members can cause discomfort and pain due to the terminal region entering gaps or bending when worn, leading to direct contact with the measurement site.

Innovation Solution

A blood pressure cuff design featuring a band with a ring-like member and an auxiliary member in the terminal region, where the first and second skin members are welded or bonded together with the auxiliary member sandwiched between them, increasing the terminal region's rigidity and preventing it from passing through the ring-like member, thus reducing discomfort and improving durability and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a plate-like member is embedded in the terminal region to improve wearability, then the ring member is prevented from direct contact with measurement site, but the terminal region may enter gap or bend causing pain

Engineering Contradiction:

ImprovewearabilityVSAvoidpain

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical state of the terminal region by welding or bonding the first and second skin members together, transforming the flexible terminal region into a rigid structure. This parameter change (from flexible to rigid) prevents the terminal region from bending or entering the ring member gap, thereby eliminating the harmful effect of pain while maintaining the wearability improvement provided by the plate-like member.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite structure by combining the plate-like member with the welded/bonded skin members in the terminal region. This composite construction integrates the wearability benefits of the plate-like member with the structural stability of the welded/bonded connection, preventing both direct contact with the measurement site and unwanted bending or gap entry that would cause pain.

Inventive Principle:

Principle #40Composite materials

2Strength

If sewing is used to attach skin members, then secure connection is achieved, but durability is reduced and appearance quality deteriorates

Engineering Contradiction:

Improveconnection strengthVSAvoiddurability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent replaces the mechanical sewing system with a welding or bonding system to attach the first and second skin members. This substitution eliminates the physical holes and seam structures associated with sewing, thereby improving durability by removing potential failure points while maintaining connection strength through the welding or bonding process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent replaces the mechanical sewing system with a welding or bonding system, which also improves appearance quality by eliminating visible seams and needle holes. The welded or bonded joint creates a smooth, continuous surface that is aesthetically superior to traditional sewn connections.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If sewing is used to attach skin members, then connection is achieved, but productivity is reduced due to multiple sewn portions

Engineering Contradiction:

Improveconnection strengthVSAvoidmanufacturing efficiency

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The patent replaces the sewing process with welding or bonding, which can be automated more easily and executed in fewer steps. This substitution reduces the number of operational stages required for attachment, thereby improving manufacturing productivity while maintaining the necessary connection strength between skin members.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent merges multiple sewing operations into a single welding or bonding process. Instead of requiring separate sewing steps for different attachment points, the welding or bonding process can simultaneously or sequentially join multiple components in one operational stage, significantly improving manufacturing efficiency.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided is a convenient blood pressure cuff. A blood pressure cuff includes a band-like body enveloping an air bag between an outer cloth and an inner cloth facing the outer cloth; a ring-like member held at a position near one end edge it in a longitudinal direction of the band-like body and extending in a lateral direction of the band-like body; and an auxiliary member stored inside a terminal region between the end edge it of the band-like body and the ring-like member and extending in the lateral direction. The outer cloth and the inner cloth in the terminal region are welded to each other in a state where the auxiliary member is sandwiched between the outer cloth and the inner cloth.
