Bicycle Wheel Holder with Automatic Retaining Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle transport systems require significant effort for mounting and securing bicycles on vehicles due to the need for manual lifting and attachment of brackets, which is cumbersome and inefficient.
Innovation Solution
A wheel holding system with a mount and movable retaining brackets that automatically lock into place when a wheel is placed in the receptacle, featuring a triggering device to secure the wheel and a locking mechanism to prevent removal, allowing for easy and secure attachment and detachment of bicycle wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual attachment of brackets and lifting of bicycles is used, then secure transport is achieved, but mounting effort and time increase significantly
Solution Approach 1:
The bicycle carrier system performs attachment actions automatically through self-service mechanisms. When the bicycle wheel is placed in the receptacle, the triggering device is activated by the wheel itself, which automatically actuates the retaining brackets to engage with the wheel and the locking device to secure it. This eliminates the need for manual bracket attachment and significantly reduces mounting effort while maintaining secure transport.
Solution Approach 2:
The retaining brackets are pre-positioned in a retracted state away from the wheel, and the locking device is pre-configured to engage automatically. The system prepares all attachment components in advance so that when the wheel is inserted, the engagement actions occur automatically without requiring manual intervention to position or attach individual components.
2Productivity
If automatic triggering device is used, then mounting speed increases, but device complexity increases
Solution Approach 1:
The triggering device combines multiple functions into a single integrated mechanism. It simultaneously activates both the retaining brackets to engage with the wheel and the locking device to secure the wheel in place. This merging of functions into one triggering mechanism achieves automatic mounting with a single simple action, avoiding the need for multiple separate complex systems.
Solution Approach 2:
The triggering device serves multiple purposes: it detects the presence of the wheel, activates the retaining brackets, and triggers the locking device. This multi-functional design achieves automatic mounting speed improvement without proportionally increasing complexity, as one component performs several critical attachment functions.
3Reliability
If retaining bracket is positioned close to wheel, then wheel security improves, but wheel insertion difficulty increases
Solution Approach 1:
The retaining bracket transitions from a static fixed position to a dynamic movable position. In the retracted state, the bracket is positioned away from the wheel to allow easy insertion. Upon triggering, the bracket dynamically moves to the engaged position where it contacts the wheel for secure retention. This dynamic positioning resolves the contradiction between insertion ease and security.
Solution Approach 2:
The retaining bracket is pre-positioned in a retracted state away from the wheel path, creating clear space for wheel insertion. The engagement action is prepared in advance but executed only after the wheel is properly positioned in the receptacle, ensuring easy insertion followed by automatic secure engagement.

AI summary
The invention relates to a wheel holding system (100) for a bicycle wheel. The wheel holding system (100) has a receptacle (110) for a bicycle wheel and at least one movable retaining bracket (120) for securing a bicycle wheel. The movable retaining bracket (120) has a first position and a second position. In the first position, the retaining bracket (120) is spaced apart from the bicycle wheel, and in the second position, the retaining bracket (120) rests against the bicycle wheel. Furthermore, the wheel holding system (100) has a locking device (130) for locking the bicycle wheel in the receptacle (110) and a release device (140). The release device (140) is designed to automatically actuate the locking device (130) as soon as a bicycle wheel is placed in the receptacle (110). By triggering the release device (140), the two retaining brackets (120) are unlocked and pressed against the positioned wheel, so that the wheel is fixed.Furthermore, the release device (140) is designed to actuate the locking device (130) after the wheel has been fixed by the retaining brackets (120) and to lock the wheel (130) in the fixed position, so that the wheel is locked in the receptacle (110).
