Moldable Bicycle Saddles With Thermal Fitting and Pressure Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle saddles often fail to provide comfortable support for riders due to anatomical variations and weight changes, leading to discomfort and the need for frequent replacement.
Innovation Solution
Customizable bicycle saddles with integrated or external heaters that mold to the rider's anatomy using thermoformable materials, allowing multiple adjustments to achieve a comfortable fit, and sensors for feedback-controlled heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bicycle saddles are used, then the saddle structure remains simple and cost-effective, but the saddle cannot adapt to anatomical variations and weight changes, leading to discomfort
Solution Approach 1:
The saddle incorporates a moldable material layer that can dynamically change its shape and properties through heating and cooling cycles, allowing the saddle to adapt to different rider anatomies and weight conditions while maintaining a relatively simple overall structure
Solution Approach 2:
The saddle utilizes temperature parameter changes to transform the material properties of the moldable layer, enabling it to become pliable for shaping during fitting and rigid for support during use, thus achieving adaptability without permanent structural complexity
2Ease of operation
If conventional bicycle saddles are used, then the saddle weight remains low, but the saddle does not provide customized support, causing discomfort and pain
Solution Approach 1:
The saddle applies the moldable material principle only to specific regions that require customization for comfort, rather than making the entire saddle complex and heavy, thus achieving improved support quality with minimal weight penalty
3Adaptability or versatility
If the rider's weight or size changes significantly, then a new saddle must be installed, but this requires additional cost and time, the existing saddle should be able to adapt
Solution Approach 1:
The saddle enables periodic remolding through heating cycles, allowing the rider to adjust the saddle fit at different times as their anatomy changes, eliminating the need for immediate saddle replacement and reducing time loss
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
Provides a highly customized fit that reduces pressure points and discomfort, enabling the saddle to adapt to changes in rider weight or size, with the ability to be remolded as needed.
Implementation Method 1
The shell is made of a moldable material that can be heated to a temperature above a glass transition temperature, a melt temperature, or a softening temperature of the material
Implementation Method 2
A pressure sensor can be positioned on the seat for interval data collection

AI summary
A bicycle saddle can be customized to a rider's body to achieve desired support and comfort. The support shell is configured to support a rider's body and can be heated by an external heater and/or at least one internal thermal element operable to heat the bicycle saddle such that the saddle is molded to the rider. A molding indicator in thermal contact with the saddle measures a molding factor, such as temperature or deflection, and visually indicates the measured molding factor for molding the bicycle saddle.
