Adjustable Bra Cups with Rotary Buckle and Modified Cellulose Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bras are inconvenient to adjust due to complex mechanisms and unsatisfactory fabric selection, leading to poor comfort and sweat absorbency.
Innovation Solution
A bra with adjustable inner cups featuring a rotary buckle and take-up assembly, allowing for easy adjustment of tightness without removing the bra, using modified cellulose fibers and a metal or nylon adjustment band for improved comfort and sweat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hooks and eyes are used for adjustment, then the bra can be adjusted, but the operation becomes complex and inconvenient
Solution Approach 1:
The patent replaces the traditional hooks and eyes mechanical adjustment system with a rotary buckle mechanism. The rotary buckle allows users to adjust the bra band by simply rotating a buckle component, which transmits the rotational motion through a rope to tighten or loosen the band. This substitution of mechanical systems simplifies the operation while maintaining adjustability.
Solution Approach 2:
The patent introduces a dynamic adjustment mechanism where the rotary buckle can be rotated to change the bra band tension in real-time. The rope connected to the rotary buckle allows continuous adjustment of the band circumference, transforming the static bra structure into a dynamically adjustable one, thereby improving ease of operation.
2Ease of operation
If rotation adjustment is used, then the distance between cups can be controlled, but the arrangement becomes unreasonable and adjustment effect is unsatisfactory
Solution Approach 1:
The patent introduces a rope as an intermediary element between the rotary buckle and the bra band. The rope transmits the rotational motion from the buckle to the band, ensuring that the adjustment force is evenly distributed and effectively transmitted. This intermediary mechanism ensures that the adjustment effect is satisfactory and the distance between cups can be precisely controlled.
Solution Approach 2:
The patent divides the adjustment mechanism into distinct functional segments: the rotary buckle for user input, the rope for force transmission, and the bra band for final adjustment. This segmentation allows each component to perform its specific function efficiently, ensuring that the overall adjustment effect is precise and satisfactory.
3Ease of manufacture
If traditional fabric selection is used, then the bra can be made, but sweat absorbency and comfort are poor
Solution Approach 1:
The patent employs composite material construction for the bra, particularly in the cup portion. The cup is made by combining a breathable base fabric with a sweat-absorbent lining material. This composite structure allows the bra to simultaneously provide breathability for air circulation and sweat absorbency for comfort, addressing the reliability requirement while maintaining ease of manufacture through standardized material combinations.
