Post-Surgery Trousers With Fold-Out Access Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing postoperative underpants for men after genital surgery are not designed for easy care, can cause chafing, require frequent removal for bladder emptying, and are often non-washable, leading to complications and discomfort.
Innovation Solution
Design of postoperative trousers with a fold-out front part, double-layered side panels, and adjustable fasteners that allow easy opening and closing without affecting the waistband, featuring a central opening for bladder emptying and washability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pants are opened for bladder emptying, then access to the genital area is improved, but the waistband slips and causes chafing
Solution Approach 1:
The front of the pants is segmented into a detachable front panel that can be opened independently from the waistband. The waistband remains closed and stable while the front panel provides access to the genital area, eliminating the problem of waistband slipping and chafing during bladder emptying.
Solution Approach 2:
The front panel is extracted as a separate detachable component from the waistband structure. This allows the front panel to be opened for access while the waistband remains intact and stable, preventing the harmful effects of waistband movement and chafing.
2Ease of operation
If underwear is repeatedly put on and taken off for bladder emptying, then access to the genital area is improved, but the healing process is impaired and complications occur
Solution Approach 1:
The pants are segmented with a detachable front panel that can be opened independently without removing the entire underwear. This allows bladder emptying while maintaining continuous wear of the supportive underwear, protecting the healing process from repeated removal and reapplication.
3Ease of manufacture
If a single central fastener is used on the waistband, then the fold-out front part can be connected, but the waistband is pulled and causes chafing
Solution Approach 1:
The single central fastener is segmented into multiple fasteners distributed at different locations (e.g., left and right sides). This distributes the pulling forces away from the central waistband area, preventing chafing and slipping while maintaining secure connection of the front panel.
Solution Approach 2:
The fastening mechanism is extracted from the central waistband location and relocated to side positions. This removes the source of central pulling forces that cause chafing, while the fasteners continue to provide secure connection of the front panel.
4Ease of manufacture
If basic mesh underpants are used, then postoperative care is simple, but support is insufficient and they are not washable
Solution Approach 1:
The design merges the simplicity of basic mesh underpants with enhanced features including a fold-out front panel with fasteners, double-layered construction for support, and washable materials. This combines ease of manufacture with improved support and reusability through machine washing.
