Triathlon Handlebar Stem Infinite Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing triathlon aero handlebar and stem assemblies have limited height adjustment capabilities, requiring the removal and reinstallation of spacers, which is time-consuming and not infinitely adjustable.
Innovation Solution
A handlebar assembly with an aerodynamically-shaped extension shaft that is slidably received in the main body, secured by a wedge clamp, allowing infinite height adjustment and tilt adjustment of the elbow platform via cap screws, enabling quick and precise positioning for maximum efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spacers are used to adjust handlebar assembly height, then height adjustment is achieved, but the adjustment process is time-consuming and not infinitely adjustable
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the extension shaft can slide within the main body along a vertical opening, allowing continuous height adjustment rather than discrete spacer-based positioning. The wedge clamp mechanism enables the shaft to be moved to any position and securely locked in place, providing both infinite adjustability and speed.
Solution Approach 2:
The patent replaces the traditional mechanical spacer system with a wedge clamp mechanism. Instead of adding or removing discrete spacer components, the wedge clamp directly actuates on the extension shaft to secure it at any desired height position, eliminating the time-consuming process of spacer manipulation.
2Ease of operation
If spacers are used to adjust elbow platform height, then height adjustment is achieved, but the adjustment requires removal and reinstallation of components
Solution Approach 1:
The patent merges the height adjustment function directly into the extension shaft and main body structure. The vertical opening in the main body and the sliding shaft create an integrated adjustment system that eliminates the need for separate spacer components, reducing both complexity and operational steps.
Solution Approach 2:
The sliding shaft mechanism provides dynamic, continuous adjustment capability within the main body structure. The shaft can be freely moved to any position and secured with the wedge clamp, eliminating the need to remove and reinstall discrete spacer components for height adjustment.
3Adaptability or versatility
If a fixed extension shaft is used, then structural simplicity is maintained, but height and tilt adjustment capabilities are limited
Solution Approach 1:
The patent transforms the fixed extension shaft into a dynamic, adjustable component. The shaft can slide vertically within the main body and is secured at any position using the wedge clamp mechanism, enabling infinite height adjustment while maintaining structural integrity.
Solution Approach 2:
The patent segments the handlebar assembly into adjustable components: the extension shaft that can slide independently within the main body, and the wedge clamp mechanism that provides independent securing capability. This segmentation enables flexible positioning without complicating the overall structure.
