Brassiere Side Support Structure for Arm-Raise Skin Movement

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing brassieres inhibit the movement of a wearer's skin on the body side when performing arm raising movements due to insufficient stretch and contraction, leading to discomfort and displacement.

Innovation Solution

A brassiere design featuring a breast support portion, a belt portion, and a body-side support portion with varying stretching properties, where the body-side support portion has a higher stretching property in the lengthwise direction than the circumferential direction, and includes openings to accommodate skin movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the brassiere uses fabric with uniform stretching properties in all directions, then the structure is simple and easy to manufacture, but the brassiere cannot follow the stretch and contraction of the skin on the body side during arm raising movements

Engineering Contradiction:

Improveease of manufactureVSAvoidadaptability to skin movement

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by differentiating the stretching properties of different portions of the brassiere. Specifically, the body-side support portion is designed with higher stretching property in the lengthwise direction compared to the breast support portion, allowing it to adapt to skin movement during arm raising movements while maintaining structural integrity in other areas.

Inventive Principle:

Principle #3Local quality

2Reliability

If the brassiere provides strong wearing compression to the chest, then the feeling of wearing is improved, but the brassiere inhibits the movement of the skin on the body side and disturbs exercise

Engineering Contradiction:

Improvewearing compressionVSAvoidease of movement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements local quality by providing different stretching properties to different portions. The body-side support portion has higher stretching property in the lengthwise direction to allow skin movement during exercise, while the breast support portion maintains lower stretching property to provide necessary wearing compression and support.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The brassiere is segmented into functionally distinct portions: the breast support portion for providing compression and support, and the body-side support portion for accommodating skin movement. This segmentation allows each portion to optimize its function without compromising the other.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the brassiere uses fabric with high stretching property in all directions, then the brassiere follows skin movement well, but the brassiere cannot provide appropriate wearing compression and support

Engineering Contradiction:

Improveadaptability to skin movementVSAvoidwearing compression

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies local quality by assigning different stretching characteristics to different portions. The breast support portion uses fabric with lower stretching property to maintain wearing compression and support, while the body-side support portion uses fabric with higher stretching property in the lengthwise direction to follow skin movement during arm raising.

Inventive Principle:

Principle #3Local quality

4Reliability

If the brassiere lateral end is positioned outside the verge line for better breast support, then the support function is improved, but the brassiere generates displacement from the skin on the body side during movement

Engineering Contradiction:

Improvebreast support functionVSAvoidstability of brassiere position

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent implements local quality by positioning the body-side support portion at the verge line lower side with higher stretching property, allowing this specific area to adapt to skin movement and prevent displacement, while the breast support portion maintains its support function with appropriate positioning and fabric properties.

Inventive Principle:

Principle #3Local quality

AI summary

The brassiere 100 includes the breast support portion 1 arranged at the chest of the wearer, the belt portion 2 arranged from the lower side of the breast support portion 1 to the back portion, and the body-side support portion 3 connected to the lateral end 11 of the breast support portion 1 and arranged from the body side to the back portion. The stretching property of the body-side support portion 3 in the lengthwise direction is higher than that in the circumferential direction.
