Bicycle Saddle with Compressible Nose and Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle saddles fail to provide comfortable and stable support for riders across various cycling positions, leading to discomfort and loss of control when transitioning between upright and aerodynamic positions, due to inadequate anatomical design and focus on weight reduction and aesthetics.
Innovation Solution
A bicycle saddle design featuring a rearward seat portion with a centrally disposed soft compressible nose and downwardly sloping lateral flanges that provide continuous support to the ischial tuberosities and absorb pressure on the pudendal region, maintaining contact and control through all cycling positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the saddle is designed to be smaller, narrower, lighter, and harder for racing positions, then weight reduction is achieved, but comfort and anatomical support are worsened
Solution Approach 1:
The saddle applies different material properties to different regions: the nose uses soft compressible material for pudendal region support, the seat portion uses firmer material for ischial tuberosity support, and lateral flanges provide structured support. This localized differentiation allows the saddle to be anatomically appropriate in each zone without requiring overall increased weight.
Solution Approach 2:
The saddle is divided into functionally distinct segments: a nose portion for perineal support, a seat portion for sit bone support, and lateral flanges for positional support. Each segment can be optimized independently for its specific function, allowing weight reduction in non-critical areas while maintaining comfort in critical zones.
2Stability of the object's composition
If the saddle nose is made hard for structural support, then stability is improved, but discomfort and pressure on the pudendal region increase
Solution Approach 1:
The nose portion specifically uses soft compressible material to reduce pressure on the pudendal region while the lateral flanges and seat portion maintain firmer structures for stability. This localized softness in the nose area eliminates harmful pressure without compromising overall saddle stability.
3Ease of operation
If the saddle is designed for upright cruising position with more cushioning, then comfort in cruising position is improved, but aerodynamic performance and support in racing position are worsened
Solution Approach 1:
The saddle design with lateral flanges and anatomical nose provides universal support for multiple cycling positions. The lateral flanges support the rider in both upright and aerodynamic positions, while the anatomical nose accommodates the pudendal region regardless of position, making the saddle adaptable to both cruising and racing conditions.
Solution Approach 2:
The saddle maintains consistent anatomical support parameters (nose support, flange positioning) across different riding positions. By keeping the structural parameters constant rather than changing cushioning levels, the saddle provides reliable support in both upright and aerodynamic positions without compromising either comfort or performance.
4Object-affected harmful factors
If the saddle lacks a centrally disposed nose or has a split nose design, then perineal pressure distribution may be improved, but loss of control and stability during position transitions occurs
Solution Approach 1:
The centrally disposed nose provides localized support to the pudendal region with soft compressible material, distributing pressure appropriately in this specific area. The presence of a central nose rather than split or absent design maintains stability during position transitions while still protecting the perineal region through localized softness.
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 saddle design ensures comfortable support and control across all cycling positions, reducing discomfort and preventing loss of contact, thereby enhancing performance and rider stability during transitions.
Implementation Method 1
a centrally disposed soft compressible nose adapted to support the rider's pudendal or pelvic anatomy
Implementation Method 2
the nose adapted to support the rider's pudendal or pelvic anatomy
Implementation Method 3
the sloping flanges provide continuous support to the ischial tuberosities as the rider slides forwardly and downwardly

AI summary
A bicycle saddle for attaching to a bicycle seat post including a rearward seat portion extending forwardly to a soft compressible nose. The seat portion adapted to support a rider's ischial tuberosities in the cruising position. The nose adapted to support the rider's pudendal or pelvic anatomy. The seat portion having downwardly sloped lateral flanges disposed either side of the nose wherein the flanges continue to provide support to the ischial tuberosities. Any increase in perineal and pudendal pressure is substantially absorbed by the compressibility of the nose such that maintaining continuous contact with the seat portion and nose enables full saddle control as the rider shifts from the cruising to an aerodynamic or racing position.
