Undergarment Modular Connecting System for Shirt Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing shirts within pants or skirts are uncomfortable, create visible lines, and fail to maintain a professional appearance due to their design, which often attach to the shirt tails or require attachment around both legs.
Innovation Solution
An undergarment with front and back panels featuring elastic bands that extend across the thigh and under the buttocks, respectively, and dual clasp connectors that attach to the side seams of shirts or blouses, providing a secure and comfortable fit without visible lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing undergarment systems attach around both legs or connect to shirt tails, then the shirt is secured within the waistband, but the device becomes uncomfortable and creates visible lines under clothing
Solution Approach 1:
The patent extracts the attachment mechanism from the problematic locations (both legs and shirt tails) and relocates it to a single concealed location at the center front of the undergarment. The connector is positioned to attach to the shirt front below the waistband, removing the shirt tail attachment that caused discomfort and visible lines while maintaining effective shirt retention.
Solution Approach 2:
The patent introduces an intermediary connector mechanism that mediates between the undergarment and shirt. This connector attaches to the shirt front (not the tail) and connects to the undergarment at a concealed location, serving as an intermediate attachment point that eliminates direct contact between the undergarment bands and the shirt tail, thereby preventing visible lines and discomfort.
2Reliability
If existing systems use elongate members connecting front and back of shirt to waistband, then shirt is secured, but the device creates creases and visible lines that defeat the professional appearance goal
Solution Approach 1:
The patent removes the elongate members that connect the back of the shirt to the waistband, extracting the problematic attachment mechanism from visible areas. The connector is repositioned to attach only at the front center below the waistband, eliminating the rear attachment points that created visible lines and creases in the shirt and undergarment.
Solution Approach 2:
The patent applies local quality by concentrating the attachment function at a single concealed location at the center front, rather than distributing attachment points across the back and sides. This localized attachment approach ensures that the connector is positioned where it will not create visible lines or creases, maintaining the professional appearance while still securing the shirt effectively.
3Reliability
If elastic bands extend across the body to secure shirts, then shirts remain tucked in during active movements, but visible lines are created under pants or skirts
Solution Approach 1:
The patent extracts the elastic band attachment from visible areas and relocates it to a concealed location at the center front of the undergarment, below the waistband. The elastic band is positioned horizontally across the front, parallel to the waistband, and the connector attaches to the shirt front in a location that is concealed by the waistband and clothing, eliminating visible lines while maintaining shirt retention during active movements.
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 undergarment effectively keeps shirts tucked in, maintaining a professional appearance by distributing the elastic bands discreetly across the body, ensuring the shirt remains within the waistband even during active movements, while being comfortable and invisible under clothing.
Implementation Method 1
an elastic band arranged on the front panel along the top edge and extending beyond the front panel parallel to the top edge, an elastic band arranged on the back panel along the top edge and extending beyond the back panel parallel to the top edge

AI summary
An undergarment including a front panel having a top edge, an elastic band arranged on the front panel along the top edge and extending beyond the front panel parallel to the top edge. The undergarment further includes a back panel having a top edge, the elastic band arranged on the back panel along the top edge and extending beyond the back panel parallel to the top edge, and a pair of connectors secured to the elastic band and configured to attach to a side seam of a blouse or shirt.
