Dual Wheel Mounting Device for Heavy Construction Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel mounting devices for heavy construction equipment fail to prevent sinking in wet and muddy soil conditions and allow debris to get caught between wheels, leading to reduced operational efficiency, stability, and safety.
Innovation Solution
A dual tire mounting device featuring an inner wheel mount connected to an axle with outwardly extending fins and U-shaped ribs, an outer ring, and a separator ring, designed to reduce ground pressure and facilitate floating over wet and muddy surfaces.

Engineering Contradiction Analysis
1Force
If multiple wheels are mounted on heavy construction equipment, then load bearing capacity is improved, but ground pressure increases causing equipment to sink in wet and muddy soil
Solution Approach 1:
The wheel assembly is segmented into an inner wheel and an outer wheel mounted side-by-side on the same axle. This segmentation distributes the load across two separate contact patches with the ground, effectively reducing ground pressure while maintaining load bearing capacity. The separator ring further segments the space between wheels to prevent debris entrapment.
Solution Approach 2:
The invention transitions from a single-wheel configuration to a dual-wheel configuration by adding the outer wheel dimension. This dimensional change increases the total contact area with the ground without increasing the vertical load, thereby reducing ground pressure and preventing sinking in soft terrain.

If multiple wheels are mounted close together, then space is conserved, but debris becomes trapped between wheels causing operational problems
Solution Approach 1:
A separator ring is introduced as an intermediary component between the inner and outer wheels. This separator ring prevents debris from becoming trapped between the wheels while maintaining compact spacing. The separator ring acts as a mediator that allows the dual-wheel configuration to function effectively without the harmful effect of debris entrapment.
Solution Approach 2:
The separator ring is positioned specifically in the critical region between the wheels where debris entrapment occurs. This localized application of the separator ring addresses the debris problem without affecting the overall compact design of the wheel assembly.
