Vertical Bike Stand Paw-and-Rack Locking for Stable Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical bike stands face difficulties in orienting and locking the connection tube, leading to troublesome adjustments and potential bicycle instability when the positioning bolt is not rotated tightly, causing the bicycle to fall.
Innovation Solution
A vertical bike stand design featuring a connector with an operation portion and orientation segment, utilizing a resilient element to engage a paw with a toothed section, allowing for controlled movement and orientation of the support tube, ensuring stable positioning of the bicycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a positioning bolt is used to lock the connection tube, then the bicycle can be fixed in position, but the adjustment and locking process becomes troublesome and time-consuming
Solution Approach 1:
The connector allows the support tube to dynamically adjust to different angles and positions during operation, then locks firmly when positioned. The connection tube can rotate and tilt freely during adjustment, then becomes stable when locked by the positioning bolt, transforming from a static rigid connection to a dynamic adjustable one.
Solution Approach 2:
The connector is divided into multiple independent components: the connection tube for angle adjustment, the positioning bolt for locking, the resilient element for cushioning, and the operation portion for control. This segmentation allows each component to perform its specific function independently, making the overall system both adjustable and reliable.
2Ease of operation
If the positioning bolt is not rotated tightly, then the adjustment process is faster, but the connection tube may be released causing the bicycle to fall
Solution Approach 1:
The resilient element automatically engages with the positioning rack teeth to lock the connection tube in place without requiring tight rotation of the positioning bolt. The system self-locks through the elastic force of the resilient element pressing against the toothed section, providing reliable locking while maintaining ease of operation.
Solution Approach 2:
The positioning rack with its toothed section acts as an intermediary mechanism between the connection tube and the locking system. The resilient element engages with these teeth to provide positive locking, transforming the direct bolt-to-tube connection into a multi-stage locking process that is both reliable and easy to operate.
3Adaptability or versatility
If the connection tube is adjusted to different angles, then the support portion can reach desired positions, but the orientation control becomes difficult
Solution Approach 1:
The connector enables dynamic orientation control where the connection tube can be freely adjusted to different angles during operation. The support tube and holder can tilt and rotate to various positions, then be locked firmly once the desired orientation is achieved, making both position flexibility and orientation control easy.
Solution Approach 2:
The connector adds rotational and tilting dimensions to the connection between the support tube and holder. Instead of fixed linear movement only, the system now includes angular adjustment capabilities in multiple dimensions, allowing the support portion to reach desired positions while maintaining easy orientation control through the operation portion.

AI summary
A vertical bike stand contains: a base, a coupling column, a guide groove, and a positioning rack. The positioning rack includes a toothed section, and the support tube includes a channel. A holder is arranged on the support tube and is configured to close the channel and includes two prongs and a recess. A fixer is fitted on the support tube and is rotatably connected with a connector. The connector includes a shaft rotatably connected with the fixer, a press tab extending from an upper end of the connector, an operation portion extending outward from the press tab, an orientation segment extending into the guide groove from a lower end of the connector, and a paw extending from the orientation segment and configured to engage with the toothed section. The orientation segment is pushed by a first resilient element to fix in the fixer.
