Adjustable Bicycle Rack with Movable Compartments and Hanging Shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle racks are inconvenient due to fixed intervals between vertical rods, which cannot accommodate different bicycle models and do not allow for the hanging of riding accessories, leading to instability and the need for riders to carry these items.
Innovation Solution
A bicycle rack with movably disassembled compartment bars and hose sleeves that adjust to different wheel widths, along with a hanging shelf for accessory storage, providing stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed interval vertical rods are used in the bicycle rack, then the structure is simple and stable, but it cannot accommodate different bicycle models and wheel sizes
Solution Approach 1:
The compartment bars are designed to be movable rather than fixed, allowing them to be adjusted to different positions. This dynamic adjustment capability enables the rack to accommodate various bicycle wheel sizes and models while maintaining structural simplicity through the use of standard connection mechanisms.
Solution Approach 2:
The rack is divided into modular components including adjustable compartment bars and detachable hose sleeves. This segmentation allows each component to be independently adjusted or removed, providing versatility for different bicycle types while keeping the overall structure manageable and not overly complex.
2Ease of operation
If multiple bicycles are parked side by side in the existing rack, then the parking capacity is maximized, but there is almost no gap between adjacent bicycles making it difficult to hang riding accessories
Solution Approach 1:
The hanging shelf is added as a new dimensional element above the bicycles, providing a separate space for storing riding accessories. This allows riders to hang items without requiring horizontal space between bicycles, thus maintaining high parking capacity while improving ease of operation for accessory storage.
3Adaptability or versatility
If the interval between vertical rods is fixed, then the manufacturing is simple and cost-effective, but it cannot be adapted to different wheel widths of bicycles
Solution Approach 1:
The compartment bars are designed with movable connections that allow them to be repositioned along the vertical rods. This dynamic adjustment mechanism provides adaptability to different wheel widths while maintaining manufacturing simplicity through the use of standard adjustment holes and connection pieces that can be easily manufactured.
4Reliability
If hose sleeves are added to the compartment bars, then the bicycle stability is improved for different wheel widths, but the device complexity increases
Solution Approach 1:
Hose sleeves are used as flexible components that can be easily attached to the compartment bars. These flexible sleeves provide the necessary stability and adjustment capability for different wheel widths while adding minimal complexity compared to rigid mechanical adjustment mechanisms, as they can be simply slipped onto the bars and tied or clipped in place.

AI summary
A bicycle rack includes a frame body, compartment bars, hose sleeves and a hanging shelf. The frame body includes two side frames, an upper frame bar and a lower frame bar which are connected between the two side frames. The compartment bars are movably disposed between the upper frame bar and the lower frame bar, and arranged in interval. The hose sleeves are movably mounted on the compartment bars, respectively. The hanging shelf is disposed on one of the two side frames. Each compartment bar can be movably disassembled to adjust an interval between the adjacent two compartment bars; each compartment bar is mounted with a hose sleeve, and even if a wheel width of a bicycle is slightly lower than the interval between the adjacent two compartment bars, the bicycle can be prevented from shaking when being tightened by the hose sleeves.
