Solution Overview

Problem

Conventional sports bras are cumbersome to put on, lack adjustable tension options, and require reaching behind the back to adjust fit, which is inconvenient during athletic activities.

Innovation Solution

A sports bra design with integrated strap portions that can be adjusted from the front, allowing for easy tension adjustment without encumbering the user, featuring a cup portion, base portion, and strap portions that wrap around the torso for a sleek and supportive fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a pre-sized sports bra with non-adjustable elastic rib band is used, then the bra structure is simple, but it is cumbersome to put on and lacks adjustment options for modifying tension

Engineering Contradiction:
Improvebra structureVSAvoidease of donning and adjustment
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The sports bra is divided into separate components: a base portion and adjustable strap portions. The strap portions can be independently attached and adjusted, allowing the bra to be put on more easily without requiring the entire garment to be stretched over the head. This segmentation enables partial adjustment while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If straps are positioned at the back to fasten together, then the bra provides secure fit, but the user needs to reach behind her back to readjust tension which is inconvenient during activity

Engineering Contradiction:
Improvefit securityVSAvoidadjustment convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adjustment mechanism is inverted from the conventional back-positioned straps to front-positioned straps. The strap portions extend forward to the front surface of the base portion, allowing users to adjust tension by manipulating clips at the front rather than reaching behind the back. This inversion maintains secure fit through the same fastening mechanism while dramatically improving adjustment accessibility during athletic activities.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If adjustable straps are added to allow tension modification, then the bra provides tailored fit, but the design becomes clunky and encumbers the user during activity

Engineering Contradiction:
Improvetension adjustment capabilityVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The strap portions are designed as dynamic, flexible elements that can be attached or detached from the base portion. The clips enable quick attachment and detachment without complex mechanisms. This dynamic design allows the bra to adapt to different support needs while maintaining a sleek profile when straps are attached, avoiding the clunky appearance of permanently integrated adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

AI summary

A sports garment includes a cup portion that receives and conforms to a user's breasts, a base portion disposed along a bottom edge of the cup portion, a first strap portion disposed along a first side edge of the base portion, and a second strap portion disposed along a second side edge of the base portion. The first and second strap portions each include a shoulder strap that may be removably coupled to the cup portion to adjust the tension of the sports garment and a side strap that may be removably coupled to a front surface of the base portion to adjust the tension of the sports garment. The first and second side straps may flex between an open position and a wrapped position.
