Vehicle Wheel Parasol Rack With Multi-Arm Tire Clamping Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted parasol racks fail to securely hold large-sized parasols, as they can be blown down or tipped by external forces, even when properly inserted into wheel clamping devices.
Innovation Solution
A vehicle-carrying leisure-purpose parasol rack with a screw rod, connection ring, clamp arms, and assisting member that securely attaches to a vehicle wheel, allowing a parasol post to be inserted and stabilized, featuring a hollow tubular grip, retaining notches, and torsion springs for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple wheel clamping device is used to attach the parasol, then the device is easy to carry and install, but the parasol can be blown down or tipped by external forces
Solution Approach 1:
The clamping device is divided into multiple clamp arms (typically three) that are distributed around the wheel, each independently clamping the tire wall. This segmentation allows the structure to distribute external forces (wind, rain) across multiple attachment points, significantly improving stability while maintaining ease of installation through modular assembly
Solution Approach 2:
The clamp arms are designed with specific local features: hook-shaped clamping terminals for gripping the tire wall, mounting terminals for connection to the connection ring, and integrated torsion springs for automatic tensioning. These localized structural qualities enable each component to perform its specific function optimally, ensuring reliable parasol support
2Reliability
If a secure clamping structure with multiple clamp arms is used, then the parasol stability is improved, but the device complexity increases
Solution Approach 1:
Multiple functional elements are merged into integrated components: the clamp arm combines the clamping terminal, extension section, and mounting terminal into a single piece; the connection ring integrates the thread for the screw rod with multiple retaining notches for mounting terminals; the torsion spring is integrated directly into the clamp arm structure. This merging reduces the number of separate parts and simplifies assembly while maintaining structural stability
Solution Approach 2:
The clamp arms incorporate torsion springs that provide dynamic automatic tensioning as the parasol experiences external forces. The springs allow the clamp arms to flex and adjust to wind pressure or rain weight, maintaining optimal clamping force without requiring complex mechanical adjustment mechanisms, thus improving stability while keeping the structure relatively simple

Function Achieved in This Case
The solution provides a stable and secure means to hold large-sized parasols, preventing them from being turned or fallen by external forces, eliminating the need for additional weights or ropes, and allowing easy carrying and adjustment.
Implementation Method 1
a torsion spring is arranged between each of the clamping terminals and each of the extension sections

AI summary
A vehicle-carrying leisure-purpose parasol rack includes a screw rod including a hollow tubular grip and a holding seat attached thereto; a connection ring having a thread in mating engagement with the screw rod; a plurality of clamp arms, each of which includes a clamping terminal in a hook form, an extension section, and a mounting terminal, the clamping terminal and the mounting terminal being arranged on two opposite ends of the extension section, the mounting terminals respectively corresponding to retaining notches formed in the connection ring so that the clamp arms are detachably connected to the connection ring; and an assisting member having a fixed terminal and a hollow tubular terminal. The fixed terminal is detachably connected to the extension section of one of the clamp arms, such that the hollow tubular terminal is in alignment with the hollow tubular grip.
