Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle parking racks face difficulties in accommodating bicycles of varying tire sizes and ensuring stability, often requiring multiple racks and posing risks of the bicycles falling or hitting objects during placement or removal.
Innovation Solution
A bicycle parking rack design featuring a base with adjustable first and second portions, including tubes and hooks that can accommodate different tire sizes by contacting multiple points on the tire for stability, and a connection unit allowing multiple racks to be linked for secure parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional parking racks are used, then they can hold bicycles, but they cannot accommodate bicycles of different tire sizes and require multiple racks
Solution Approach 1:
The parking rack incorporates adjustable components including a first part with adjustable height and position, and a second part with adjustable position, allowing the rack to dynamically adapt to different bicycle tire sizes. This dynamic adjustability eliminates the need for multiple fixed racks for different bike types.
Solution Approach 2:
The parking rack is designed as a universal device that can accommodate various bicycle types (mountain bikes with 26-29 inch tires, road bikes with 650-700 mm tires) through its adjustable first and second parts, making a single rack serve multiple functions that previously required multiple specialized racks.
2Area of stationary object
If wall-mounted parking racks are used, then they do not occupy floor space, but it is difficult to place or remove bicycles safely
Solution Approach 1:
The parking rack positions the bicycle wheel at a height that makes placing and removing bikes effortless, eliminating the need for awkward lifting or climbing actions required by wall-mounted racks. The adjustable first part allows the contact point to be at an ergonomically optimal height.
Solution Approach 2:
The rack design with its adjustable components and stable base allows users to easily place and remove bicycles without requiring complex manipulation or risking bicycle falls, making the operation intuitive and safe.
3Adaptability or versatility
If multiple parking racks are used to accommodate different bicycles, then various bike sizes can be parked, but the stability and weight support of multiple separate racks is required
Solution Approach 1:
The patent combines multiple functional elements (first part with adjustable height, second part with adjustable position, hook end, and stable base) into a single integrated rack structure, providing both adaptability for different bike sizes and the stability of a unified design in one device.

AI summary
A bicycle parking rack includes a base to which a first portion is connected. Two first parts are adjustably connected to the first portion. A second portion connected to the base at an angle. The second portion includes a first tube, a second tube and a third tube. A second part is adjustably connected between the first tube and the third tube. A bicycle wheel contacts the two first parts and the second part to form three contact points. The second tube is inserted into the upper end of the first tube and includes a hook end which may hook to an inner periphery of a bicycle wheel. A connection unit is removably connected between two respective bases of two parking racks.
