Motorcycle Garment Elastic Insert Segmentation for Fit and Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcyclist suits face challenges in balancing aerodynamics and comfort while providing adequate protection, particularly at the sides and back, due to complex manufacturing processes and weight issues with existing elastic inserts, which can lead to displacement of protective elements during accidents.
Innovation Solution
A garment design incorporating elastic inserts connected by non-stretchable elements, combined with stretchable pieces and panels, ensures flexibility and protection without increasing weight or compromising aerodynamics, featuring accordion leather stretch inserts and Kevlar fabric for enhanced comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If U-shaped elastic strips are applied along the sides and back of the suit, then the suit provides flexibility for rider movement, but the manufacture becomes complex and the back protections can displace during accidents
Solution Approach 1:
The elastic strip is divided into three separate pieces (first piece along the side, second piece along the bottom of the back, third piece along the other side) that are joined by connecting elements. This segmentation simplifies manufacturing by allowing each piece to be produced and attached independently, while still providing the necessary flexibility for rider movement throughout the back and side areas.
2Stability of the object's composition
If inextensible material is used for the suit, then the suit maintains aerodynamic properties, but the suit hinders rider movement
Solution Approach 1:
The suit uses inextensible material for most of the body to maintain aerodynamic properties, but incorporates elastic strips in specific locations (along the sides and bottom of the back) where flexibility is needed for rider movement. This local differentiation allows the suit to be aerodynamic overall while providing necessary flexibility in key movement areas.
3Ease of operation
If accordion leather stretch inserts are applied along all sides of the trunk, then the suit provides flexibility for arm raising and back arching, but the suit cannot accommodate side protections and creates weight issues
Solution Approach 1:
Instead of applying elastic inserts along all sides of the trunk, the invention places elastic strips only in specific locations (along the sides and bottom of the back) where flexibility is needed. This allows other areas to accommodate rigid or semi-rigid side protections, combining flexibility where needed with protection where required.
4Ease of operation
If multiple elastic inserts are added to the suit, then the suit provides improved flexibility, but the weight of the suit increases
Solution Approach 1:
Instead of adding elastic inserts to the entire suit, the invention applies them partially only in specific areas (along the sides and bottom of the back) where flexibility is most needed for rider movement. This partial application provides the necessary flexibility while minimizing the added weight compared to a full-coverage elastic insert design.
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 design enhances comfort and protection for motorcyclists by maintaining adherence to the body, reducing weight, and simplifying manufacturing, while allowing for improved flexibility and side protection without compromising aerodynamic properties.
Implementation Method 1
a first piece of elastic fabric, a second piece of elastic fabric and a third piece of elastic fabric
Implementation Method 2
The two elastic inserts are connected to the elastic band by means of at least one not-stretchable element, running along the sides of the trunk

AI summary
The present invention relates to a garment for motorcyclists (10) comprising a panel (12) formed by two elastic inserts (14), each elastic insert (14) having a first portion (141), positioned underneath the respective armpit, along the side of the upper portion of the trunk, and a second portion (142), inclined upwards over the respective shoulder blade, and by an elastic band (16), crosswise positioned along the bottom portion of the back. According to the invention the two elastic inserts (14) are connected to the elastic band (16) by means of at least one not-stretchable element (18), running along the sides of the torso. Moreover the garment (10) comprises two further stretchable pieces (20), each stretchable piece (20) running along the inner side of the sleeve from the wrist up to the armpit and being provided with an extension (22) extending along the adjacent side of the upper portion of the trunk and joined to the first portion (141) of the adjacent elastic insert (14).
