Bicycle Handlebar Integrated Aero Measuring Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for measuring the coefficient of drag area (CdA) on bicycles are bulky and interfere with performance, as they are permanently or semi-permanently attached to the handlebar, increasing CdA and reducing the effectiveness of the data they collect.
Innovation Solution
A bicycle handlebar with an integrated aero measuring device housed within the frame structure, featuring a pitot tube exposed to external air and a notification system that reports changes in CdA in real-time through visual, auditory, or haptic alerts, allowing for on-the-go data collection without performance impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standalone CdA measuring device is attached to the bicycle handlebar, then CdA measurement capability is improved, but the device's bulkiness increases CdA and reduces measurement accuracy
Solution Approach 1:
The patent merges the CdA measuring device with the bicycle handlebar into a single integrated unit. The measuring device is housed within the handlebar's internal space, eliminating the need for separate attachment and removing the harmful aerodynamic impact of external mounting while preserving measurement functionality.
Solution Approach 2:
The measuring device is nested within the handlebar structure, specifically housed in the internal space formed by the handlebar tubes. This nesting approach allows the measuring components to be contained within the existing aerodynamic profile of the handlebar, preventing additional drag.
2Duration of action of stationary object
If a permanent CdA measuring device is attached to the handlebar, then continuous measurement is improved, but the device becomes a permanent source of drag
Solution Approach 1:
By combining the measuring device with the handlebar structure itself, the system enables continuous measurement without adding separate permanent attachments that would create ongoing aerodynamic drag and energy loss.
3Measurement precision
If a bulky measuring device is used, then measurement functionality is improved, but the device's size increases its aerodynamic drag
Solution Approach 1:
The measuring device components are nested within the handlebar's internal tubing structure, utilizing the existing volume of the handlebar rather than adding external bulk. This allows functional measurement capabilities to be housed within the aerodynamic profile already established by the handlebar design.
Solution Approach 2:
The patent moves the measuring device from an external three-dimensional attachment to an internal configuration within the handlebar tubes. This dimensional repositioning reduces the device's external aerodynamic profile while maintaining internal measurement functionality.
