Bicycle Parking Rack with Curved Support Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle parking racks fail to securely support bicycles, leading to easy falling due to the angle at which bicycles are parked, and they do not efficiently accommodate bicycles of different tire sizes.
Innovation Solution
A bicycle parking rack design featuring restriction members with curved sections and support members with recessed areas to accommodate various wheel sizes, preventing brake interference and allowing adjustable metal tube assembly for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional parking racks are used to park bicycles in a row, then space utilization is improved, but bicycles easily fall down due to unstable support
Solution Approach 1:
The support members have different structures at different locations: the first support member has a curved surface to accommodate the bicycle wheel, while the second support member has a planar surface. This local differentiation provides stable support for the bicycle, preventing it from falling while maintaining space utilization.
Solution Approach 2:
The first support member features a curved surface that conforms to the circular shape of the bicycle wheel. This curvature provides stable contact and support, preventing the bicycle from falling while allowing it to be parked in a compact arrangement for efficient space utilization.
2Reliability
If restriction members are designed to hold bicycles securely, then bicycle stability is improved, but brake systems or quick-releases may be hit and damaged
Solution Approach 1:
The design extracts the harmful function of the restriction member contacting the brake system by introducing a recessed area. The restriction member is positioned such that its connection section does not contact the brake system or quick-release, eliminating the damage risk while maintaining bicycle stability through proper wheel restriction.
Solution Approach 2:
The recessed area acts as an intermediary space between the restriction member and the brake system. This design feature allows the restriction member to securely hold the bicycle wheel while preventing direct contact with the brake system, thus avoiding damage.
3Ease of manufacture
If parking racks are designed for standard wheel sizes, then manufacturing simplicity is maintained, but bicycles with different tire sizes cannot be accommodated
Solution Approach 1:
The support members are designed with dual functionality: the first support member with a curved surface accommodates standard bicycle wheels, while the second support member with a planar surface accommodates different wheel sizes. This universal design allows the same parking rack structure to handle various wheel dimensions without complicating manufacturing.
Solution Approach 2:
Different portions of the support members have different geometries (curved vs. planar surfaces) to accommodate different wheel sizes. This local differentiation in the support structure enables versatility in handling various tire sizes while maintaining overall manufacturing simplicity through a unified component design.

AI summary
A bicycle parking rack includes a rectangular base and at least two restriction members are connected to the base. Each restriction member includes two first sections and a connection section formed between the two first sections. Two support members are respectively connected between the at least two restriction members. Each support member includes a support portion and two connection portions which are formed on two sides of the support portion. The two connection portions are respectively connected to the two first sections of the at least two restriction members corresponding thereto. The support portion of each support member has a recess which accommodates a portion of a bicycle wheel. The restriction members of the bicycle parking rack restrict the bicycle wheel between the two restriction members.
