Post-Op Compression Bra with Adjustable Strap Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compression bras cause discomfort due to skin scratching from hook and loop fasteners, nipple irritation from seams, and pressure on lymph nodes from side straps, failing to effectively reduce swelling and bruising after breast surgery.
Innovation Solution
A post-operative compression bra design featuring strap clips for adjustable pressure, rounded notches on side portions to avoid lymph nodes, and partial mesh construction for airflow, along with a seamless interior to prevent irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hook and loop fasteners are used to secure the bra, then the bra can be fastened securely, but the fasteners scratch the patient's skin causing discomfort
Solution Approach 1:
The patent removes the harmful hook and loop fasteners from the bra design entirely. Instead, it uses a front opening with overlapping edges that are secured using alternative fastening mechanisms positioned away from direct skin contact areas, thereby extracting the source of skin irritation while maintaining securing functionality
Solution Approach 2:
The patent introduces an intermediary smooth fabric layer or edge finish between the fastening mechanism and the patient's skin. This intermediary element prevents direct contact between rough fastener surfaces and sensitive post-surgical skin, eliminating scratching while preserving the securing function
2Device complexity
If seams are located down the middle of each cup, then the bra structure is simplified, but the seams rub against the nipple causing irritation
Solution Approach 1:
The patent removes seams from direct contact with the nipple area by repositioning them to the outer edges of the cups or eliminating them entirely in favor of seamless knitting techniques. This extraction of harmful seams from sensitive areas prevents rubbing and irritation while maintaining the structural integrity needed for compression support
Solution Approach 2:
The patent applies different construction qualities to different parts of the bra: seamless or edge-positioned seams in the cup areas that contact sensitive skin, while maintaining necessary seam structures in non-contact areas for structural support. This local differentiation eliminates irritation where it matters most while preserving overall bra functionality
3Force
If side straps wrap around the torso, then the bra provides lateral support, but the straps press against lymph nodes under the armpits causing discomfort
Solution Approach 1:
The patent segments the side strap into two separate components: an upper portion that clears the armpit area to avoid lymph node pressure, and a lower portion that provides lateral support lower on the torso. This segmentation allows the bra to maintain lateral support functionality while eliminating pressure on sensitive lymph nodes during healing
Solution Approach 2:
The patent relocates the lateral support function from the traditional side strap position (wrapping around the torso at mid-level) to alternative positions such as lower on the torso or using vertical back panels. This dimensional relocation of support forces away from the armpit area eliminates lymph node pressure while maintaining necessary lateral compression support
4Ease of manufacture
If the bra uses conventional fastening and strap design, then manufacturing is simplified, but adjusting the pressure exerted on the patient becomes difficult
Solution Approach 1:
The patent incorporates dynamic, adjustable elements into the bra design such as multiple fastening positions, adjustable strap lengths, or expandable sections that allow the compression pressure to be modified. These dynamic features enable easy pressure adjustment for different healing stages or comfort needs while maintaining relatively simple manufacturing processes
Solution Approach 2:
The patent designs the bra with variable compression parameters through features like progressive compression zones, adjustable fastening systems, or modular components that can be configured for different pressure levels. This allows the compression force parameter to be easily changed by the patient or caregiver without complex manufacturing requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bra reduces swelling and bruising while minimizing discomfort by allowing easy pressure adjustment and preventing irritation at lymph nodes, promoting comfort and airflow.
Implementation Method 1
The side portions and a rear portion may also be partially constructed out of a mesh material to allow for air flow to the skin

AI summary
A post-operative compression bra (1) having an opening located between two portions, a front right portion (2) and a front left portion (3) that are secured together using strap clips (9) that allow pressure being exerted by the bra on a patient to be adjusted. Rounded notches (19) are located on an upper edge (17) of a right side portion (12) and a left side portion (13) to prevent the side portions from coming into contact with a patient's lymph nodes. The side portions and a rear portion (20) may also be partially constructed out of a mesh material to allow for air flow to the skin.
