Cycling Jersey Integrated Base Layer for Sweat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cycling garments have poor breathability and permeability, leading to sweat accumulation and discomfort during intense efforts, requiring additional underwear for sweat management, which can cause discomfort and affect performance due to mismatched properties between layers.
Innovation Solution
A cycling jersey with a permanently fixed inner lining acting as an integrated base layer, strategically covering the torso and side areas for enhanced sweat transport and thermal protection, utilizing breathable mesh fabric for the inner layer and a more resistant material for the outer layer to ensure efficient sweat removal and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single-layer structure is used for protection from outside elements, then protection is provided, but breathability and permeability are poor
Solution Approach 1:
The jersey is divided into two distinct layers: an outer layer for protection from atmospheric agents and an inner base layer for sweat management. This segmentation allows each layer to specialize in its function, with the outer layer providing durability and weather protection while the inner layer provides breathability and moisture transport capabilities.
Solution Approach 2:
The jersey combines two different materials with complementary properties: the outer layer uses a durable, weather-resistant material while the inner base layer uses a breathable, moisture-wicking material. This composite structure resolves the contradiction by allowing each material to optimize its specific function without compromising the other.
2Weight of moving object
If conventional summer jersey is designed to be light and protective, then protection and lightness are achieved, but sweat removal capability is insufficient
Solution Approach 1:
The sweat management function is segmented into a dedicated inner base layer that is permanently integrated into the jersey structure. This base layer is strategically designed with sweat-transport properties while keeping the overall jersey light, as only the necessary inner portions are lined rather than the entire garment.
Solution Approach 2:
The base layer is strategically located in specific areas where sweat accumulation is most problematic (inner portions of the jersey), rather than uniformly distributing material throughout. This localized approach provides effective sweat management where needed while maintaining overall lightness.
3Reliability
If underwear is worn underneath the sports jersey for sweat management, then sweat transport is improved, but device complexity and comfort are reduced
Solution Approach 1:
The base layer and outer jersey are permanently merged into a single integrated garment through stitching. This eliminates the need for separate underwear pieces while maintaining effective sweat transport, as the base layer functions are built-in rather than requiring an additional separate garment.
Solution Approach 2:
The integrated base layer serves multiple functions within a single structure: it transports sweat, provides thermal comfort, and maintains a streamlined fit. This multi-functionality eliminates the need for separate specialized underwear, reducing overall garment complexity while achieving comprehensive performance.
4Reliability
If underwear with different elasticity is worn under the outer garment, then sweat management is provided, but skin-tightness and aerodynamics are degraded
Solution Approach 1:
The base layer and outer layer are designed with matched elasticity coefficients, creating a homogeneous elastic response across the entire garment. This ensures that both layers move together uniformly during cycling motions, maintaining skin-tightness and aerodynamic shape without the creases and wrinkles that occur when layers have mismatched elasticity.
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 integrated base layer effectively removes sweat, maintains skin dryness and temperature stability, provides optimal thermal protection, and enhances comfort and practicality by eliminating the need for additional underwear, while ensuring a snug and aerodynamic fit.
Implementation Method 1
the inner layer is able to transport the sweat out of the body... said inner layer has greater breathability than the outer layer
Implementation Method 2
ensure an excellent fit and suitable thermal protection... provides the best compromise between lightness and performance

AI summary
A cycling garment, said garment being a jersey, a jacket or a vest having a structure realized with an outer fabric layer and further comprising an inner fabric layer having different breathability properties from the outer layer, wherein the inner layer is internally joined to the outer layer and forms an inner lining of at least part of said cycling garment.
