Movable Bicycle Rack With Vertical Base, Clamping And Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted bicycle racks are difficult to use, requiring significant effort to lift and secure bicycles, especially for women, children, or those with less strength.
Innovation Solution
A bicycle rack design featuring a movable base with a wheel fixing mechanism and a locking assembly that transitions between clamping and released states, facilitated by a rotatable locking element with hooks and pins, allowing easy vertical securing and removal of bicycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bicycle rack uses a fixed wall-mounted structure, then the storage stability is improved, but the ease of operation deteriorates because users must lift the entire bicycle to secure it
Solution Approach 1:
The base is designed to move vertically along the column, transitioning between a lower position (for easy bicycle placement) and an upper position (for secure wall-mounted storage). This dynamic positioning allows the rack to adapt to different operational states, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The locking assembly acts as an intermediary mechanism that coordinates the base position and wheel holder state. It uses locking members and hooks to mediate between the user's simple pulling action and the complex coordinated movement of the base and wheel holder, enabling easy operation while maintaining storage stability.
2Reliability
If the wheel holder maintains a constant clamping force, then the reliability of bicycle securing is improved, but the ease of operation deteriorates because the wheel cannot be easily released
Solution Approach 1:
The wheel holder transitions between a clamping state (when the locking assembly is in the first locking position) and a released state (when the locking assembly moves to the second locking position). This dynamic state change allows the wheel holder to provide strong clamping force during storage while enabling easy release during removal.
Solution Approach 2:
The wheel holder alternates between clamping and released states through periodic action of the locking assembly. The locking element rotates between positions that engage with different locking members, creating a rhythmic cycle of securing and releasing that maintains reliability while enabling easy operation.
3Reliability
If the locking mechanism uses multiple locking members and hooks, then the reliability of the locking system is improved, but the device complexity increases
Solution Approach 1:
The locking assembly integrates multiple functions into a single coordinated unit: it controls the base position along the column, manages the wheel holder state, and engages with both locking members. This merging of functions reduces the need for separate control mechanisms, maintaining reliability while managing complexity.
Solution Approach 2:
The locking element serves multiple purposes: it rotates to engage different locking members, controls the base position, and manages the wheel holder state. This multi-functionality allows a single component to perform what would otherwise require multiple separate mechanisms, balancing reliability with complexity.

AI summary
The disclosure provides a bicycle rack. The bicycle rack includes: a column (10); a wheel fixing mechanism (20), which includes a base (21), a wheel holder (22) mounted on the base, and a first locking member (23); a second locking member (30); and a locking assembly (40). The locking assembly has a first locking position, which engages with the first locking member, and a second locking position, which engages with the second locking member. When the locking assembly is in the first locking position, the first locking member contacts the wheel holder, causing the wheel holder to be in a clamping state. When the locking assembly is in the second locking position, the first locking member is separated from the locking assembly, placing the wheel holder in a released state, while the locking assembly engages with the second locking member. The technical solution of the disclosure solves problems of difficult placement and inconvenient operation found in conventional wall-mounted bicycle racks.
