Erecting device for bicycle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle erecting stands fail to securely fix a bicycle after releasing air from the tire, leading to instability and potential falling, due to the need for forceful operation of the pull shaft and lack of effective engagement with the wheel.
Innovation Solution
The proposed erecting device features rotatable connection portions with arcuate faces and dampers, a swing rack mechanism, and a stop wheel system that allows for stable engagement with the bicycle wheel regardless of size, using resilient elements and compression springs to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pull shaft is operated forcefully to rotate the first positioning support, then the positioning support can be removed from the fixing sheets, but the operation becomes difficult and requires excessive force
Solution Approach 1:
The patent applies the dynamics principle by making the positioning support rotatable and movable between different positions. The first positioning support can rotate relative to the fixing sheets, transitioning from an engaged state (when the bicycle wheel is inserted) to a removed state (when the wheel is taken out). This dynamic movement eliminates the need for forceful operation of a pull shaft, as the positioning support naturally rotates and detaches when the wheel is inserted or removed, reducing the required operating force to minimal manual guidance.
2Ease of operation
If air is released from the rubber rim, then the wheel can be removed from the groove and abutting wheel, but the bicycle will fall and cannot be fixed
Solution Approach 1:
The patent applies segmentation by separating the wheel retention function into two independent systems: (1) the groove and abutting wheel that provide initial support and enable easy wheel insertion/removal, and (2) the first positioning support that provides secondary stabilization. When air is released and the wheel is removed from the groove, the positioning support remains engaged with the fixing sheets to prevent the bicycle from falling, thus maintaining stability while preserving ease of operation.
Solution Approach 2:
The patent applies beforehand cushioning by providing the first positioning support as a pre-positioned stabilization mechanism. Before the wheel is completely removed from the groove (when air is released), the positioning support is already in place and ready to engage with the fixing sheets, cushioning against the potential instability and preventing the bicycle from falling. This preparatory stabilization ensures continuous support throughout the wheel removal process.
3Stability of the object's composition
If the first positioning support is engaged with the fixing sheets through the arcuate slot and orifices, then the structure is stable, but the design becomes complex with multiple components
Solution Approach 1:
The patent applies merging by combining multiple engagement functions into a single integrated first positioning support structure. Instead of using separate locking mechanisms, pins, and fasteners, the positioning support integrates the arcuate face for clamping, the rotation capability for engagement/disengagement, and the interaction with the arcuate slot and orifices all into one unified component. This reduces the number of separate parts while maintaining stable engagement through the combined geometric relationships between the arcuate slot, orifices, and positioning support features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures the bicycle remains upright and stable even after air is released from the tire, as the arcuate faces and stop wheel system securely clamp the wheel, allowing for easy adjustment and support without requiring forceful operation.
Implementation Method 1
The resilient element has two first returning segments. One of the two first returning segments abuts against each rotatable connection portion, and the other first returning segment is biased against a bottom of each clamper.
Implementation Method 2
The second rotatable connector has a housing room configured to a compression spring and a positioning bolt

AI summary
An erecting device for a bicycle contains at least one mounting, at least one groove, and at least one rotatable connection portion. Two rotatable connection portions are parallelly arranged on each of two ends of the at least one groove, and each of the two rotatable connection portions is rotatably connected with each of multiple dampers. Each clamper has a coupling portion for mating with each rotatable connection portion, a fixing shaft is connected with each rotatable connection portion and the coupling portion, and the fixing shaft is inserted through a resilient element. The resilient element has two first returning segments, each damper has an arcuate face parallel to each rotatable connection portion, and each damper has a receiving portion formed on the arcuate face beside each of two sides of each groove.
