Solution Overview

Problem

Conventional bras with steel rings cause discomfort, hinder blood circulation, and compress acupuncture points, leading to skin damage and health issues due to prolonged compression and friction.

Innovation Solution

A wireless bra design featuring flexible bands and a framework made of hard materials, such as silicon wafers or steel sheets, which are sewn into the gore to support and fix the cups, allowing for comfortable wear without the need for manual steel ring placement, enabling mechanized production and reducing material costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a steel ring is used to support the breast, then the breast support function is improved, but the comfort and health of the wearer deteriorates due to compression and friction

Engineering Contradiction:
Improvebreast supportVSAvoidskin damage and discomfort
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent removes the steel ring from the bra structure entirely, extracting the harmful element while maintaining breast support through alternative means (elastic bands and cup structure). This resolves the contradiction by eliminating the source of compression and friction that caused skin damage while preserving the essential support function through different mechanical principles.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the material parameter from rigid steel to flexible elastic bands, fundamentally altering the mechanical properties of the support structure. This parameter change allows the support system to adapt to breast movement and reduce compression forces, thereby maintaining support while eliminating skin damage and discomfort.

Inventive Principle:
Principle #35Parameter changes

2Shape

If a steel ring is used to improve breast shape, then the shaping function is improved, but blood circulation deteriorates due to compression

Engineering Contradiction:
Improvebreast shapeVSAvoidhindered blood circulation
Core Design Contradiction:
ShapeVSObject-generated harmful factors

Solution Approach 1:

The steel ring is completely removed from the design, eliminating the compression that hindered blood circulation. The breast shaping function is maintained through the cup structure and elastic band system that provides gentle, distributed support without constricting blood flow.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses flexible elastic bands and soft cup materials instead of rigid steel rings. These flexible components provide shaping and support through gentle pressure distribution rather than concentrated compression, allowing blood circulation to proceed unimpeded while maintaining breast shape.

Inventive Principle:
Principle #30Flexible shells and thin films

3Strength

If a steel ring is used to support the breast, then the support function is improved, but the manufacturing complexity increases due to manual placement requirements

Engineering Contradiction:
Improvebreast supportVSAvoidmanufacturing process
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

By removing the steel ring component entirely, the patent eliminates the complex manual placement process required for steel ring insertion. The support function is achieved through integrated elastic bands and cup construction that can be manufactured using standard automated sewing and assembly processes.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent integrates the support function directly into the cup structure and elastic band system, merging multiple functions into unified components. This integration eliminates separate assembly steps for steel ring installation, simplifying the manufacturing process while maintaining effective breast support.

Inventive Principle:
Principle #5Merging (Combining)

4Stability of the object's composition

If a steel ring is used to maintain breast position, then the stability is improved, but the wearer comfort deteriorates due to friction

Engineering Contradiction:
Improvebreast position stabilityVSAvoidskin irritation
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the friction parameter by replacing the smooth, rigid steel surface with textured or soft elastic band surfaces that reduce skin irritation. The elastic materials provide gentle grip and stability through distributed pressure rather than sliding friction, maintaining breast position while preventing skin irritation.

Inventive Principle:
Principle #35Parameter changes
