Bicycle parking rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle parking racks that secure bicycles horizontally are not space-efficient, leading to overcrowding and potential damage, especially in smaller display areas where multiple bicycles are showcased, resulting in a poor impression for buyers and increased risk of scratching.
Innovation Solution
A bicycle parking rack with a base and two pivotably connected support units, one of which includes an outer and inner tube with an extension rod that can secure a bicycle in either horizontal or upright positions, allowing for adjustable wheel support and seat post engagement, enabling flexible display and storage configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bicycles are displayed horizontally on existing parking racks, then the bicycle is securely restrained, but the storage space required increases and multiple bicycles crowd the display area
Solution Approach 1:
The parking rack employs a pivotable support unit that can dynamically switch between horizontal and upright positioning modes. The support unit rotates about a pivot point on the base, allowing the extension rod to transition from a horizontal wheel-restraining position to an upright seat-post engagement position, thereby adapting the space requirements based on display needs
Solution Approach 2:
The invention utilizes vertical space by enabling upright bicycle positioning. The extension rod can engage with the bicycle seat post vertically, allowing bicycles to be stored in an upright orientation rather than only horizontal, effectively using the third dimension (height) to reduce floor space occupation
2Quantity of substance
If multiple bicycles are displayed in a crowded manner to maximize space usage, then storage capacity increases, but the risk of scratching and damage increases and buyer impression deteriorates
Solution Approach 1:
The dynamic positioning capability allows bicycles to be alternately displayed in horizontal and upright orientations, creating visual variety and reducing the crowded appearance. This dynamic reconfiguration prevents the monotonic, cramped display that increases damage risk
Solution Approach 2:
The system changes the spatial parameters of bicycle display by switching between horizontal wheel restriction and vertical seat-post engagement. This parameter change from two-dimensional horizontal arrangement to three-dimensional upright positioning reduces crowding and associated damage risks

AI summary
A bicycle parking rack includes a base with a first support unit and a second support unit connected thereto. The first support unit restricts one of two wheels of a bicycle that is not in upright pose. The second support unit is pivotably connected to the base and includes an outer tube pivotably connected to the base and an inner tube that is movably inserted in the outer tube. An extension rod is threadedly connected to the inner tube and movable with the inner tube relative to the outer tube, The extension rod is configured to extend through one of the two wheels of the bicycle, or to contact a seat post of the bicycle when the bicycle is in upright pose, while the first support unit supports another one of the two wheels of the bicycle.
