Surveyor Wheel Self-Standing Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveyor wheels with dual wheels cannot stand independently and require a handle to abut against a surface for support, leading to instability when the handle's angle changes, causing the wheel to fall.
Innovation Solution
A surveyor wheel design featuring an assembling seat with a supporting element that protrudes downward to abut the ground, combined with rotatable wheels and a telescopic handle, allowing the wheel to stand independently and facilitating easy storage and access.

Engineering Contradiction Analysis
1Stability of the object's composition
If a surveyor wheel uses dual wheels without a kickstand, then it achieves better balance, but it cannot stand independently and requires external support
Solution Approach 1:
The supporting element is separated from the handle structure, creating an independent support component that protrudes downward from the assembling seat. This segmentation allows the support function to operate independently of the handle, enabling the surveyor wheel to stand without relying on the handle abutting against external surfaces.
Solution Approach 2:
The supporting element provides self-support capability directly integrated into the assembling seat structure. The element protrudes downward to abut against the ground, allowing the surveyor wheel to support itself independently without requiring external walls or objects for the handle to lean on.
2Ease of operation
If the handle of a dual-wheel surveyor wheel abuts against a wall or supporting object, then it can stand erectly, but stability is compromised when the handle's angle changes
Solution Approach 1:
The support function is separated from the handle structure into a distinct supporting element. This segmentation ensures that the supporting element provides stable ground contact independent of handle position or angle, preventing the instability that occurs when the handle's angle changes during use.
Solution Approach 2:
The supporting element acts as an intermediary between the assembling seat and the ground. It provides a dedicated support interface that transfers the weight and maintains stability without requiring the handle to contact external surfaces, thereby eliminating the instability caused by handle angle variations.
3Ease of operation
If a surveyor wheel uses a single wheel with a kickstand, then it can stand independently, but it has worse balance compared to dual-wheel designs
Solution Approach 1:
The invention merges the advantages of both single-wheel and dual-wheel designs by combining the independent standing capability (from the kickstand design) with the dual-wheel configuration. The supporting element protruding from the assembling seat provides the standing capability, while the dual wheels maintain the superior balance characteristics.

AI summary
A surveyor wheel has an assembling seat, a supporting element, a handle, and two wheels. The assembling seat has a moving direction, an upper surface, a lower surface, and two opposite ends. The upper surface of the assembling seat and the lower surface of the assembling seat are opposite each other. The supporting element is formed on the assembling seat, protrudes downward, and has a supporting end. The handle is formed on the assembling seat. The two wheels are rotatable and are respectively connected to the two opposite ends of the assembling seat. The supporting end of the supporting element is to abut against the ground or a horizontal surface to provide support.
