Pivoting Bicycle Support for Lift Vehicle Wheel Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle support devices for mechanical lift vehicles cause wheel damage and hinder loading/unloading due to wheel contact with the ground and insufficient oscillation range without striking vehicle components.
Innovation Solution
A support device with an articulated lower support that pivots between transport and loading positions, using rolling means to maintain wheel clearance and elastic return means for secure retention, allowing the vehicle to oscillate without ground contact and facilitating easy loading/unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support device is installed low on the mechanical lift vehicle, then the height-wise disposition allows the vehicle to oscillate from front to back without striking cables or pylons, but the second wheel contacts the ground causing damage and buckling
Solution Approach 1:
The lower support is made pivotable between a transport position and a loading position, allowing it to dynamically adjust its orientation. During transport, it maintains an elevated position to prevent ground contact, while during loading/unloading operations, it can pivot to accommodate wheel placement without causing damage.
2Object-affected harmful factors
If the support device is installed high on the mechanical lift vehicle, then the second wheel is kept clear of the ground, but the support device strikes cables or pylons during vehicle oscillation
Solution Approach 1:
The pivotable lower support enables the system to maintain high wheel clearance during transport while accommodating vehicle oscillation through dynamic position adjustment, eliminating the need for a fixed high installation that would restrict oscillation range.
3Device complexity
If the lower support is fixed in position, then the structure is simple and robust, but the wheel cannot maintain clearance during vehicle oscillation and causes lateral skidding
Solution Approach 1:
The pivotable lower support introduces controlled mobility to the otherwise simple structure, enabling it to adapt to vehicle oscillation and ground conditions while maintaining structural robustness. This dynamic adjustment prevents lateral skidding by allowing the support to follow the vehicle's movement rather than resisting it rigidly.
4Adaptability or versatility
If the support device allows wide oscillation range, then the vehicle can respond to wind and terrain variations, but the support device may strike cables or pylons in the mechanical lift system
Solution Approach 1:
The pivotable lower support enables the system to achieve wide oscillation range during loading/unloading operations while maintaining a more restricted, safe position during transport. This dynamic control allows the vehicle to respond to environmental conditions without colliding with fixed infrastructure elements.
