Adjustable Leveling Chock With High-Friction Bearing Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable chocks have limited transverse load capacity, which affects their ability to resist horizontal movement under mechanical loads.
Innovation Solution
The adjustable chock is enhanced with high-friction coatings on its lower bearing surface and upper bearing surface, increasing the friction coefficient between the chock and its support or machine frame, thereby enhancing transverse load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional adjustable chock design is used, then the device structure is simple, but the transverse load capacity is limited
Solution Approach 1:
The patent applies parameter changes by modifying the friction coefficient parameter of the bearing surfaces. High-friction coatings are applied to the lower bearing surface of the second component and/or the upper bearing surface of the bearing element, changing the physical parameter of surface friction from conventional levels to high-friction levels (coefficient of friction μ ≥ 0.3). This parameter change directly increases the transverse load capacity without altering the fundamental chock structure.
Solution Approach 2:
The patent employs composite materials by combining the base metal material of the chock components with high-friction coating materials. The coatings (such as tungsten carbide, ceramic coatings, or other high-friction surface treatments) form a composite surface structure that maintains the mechanical strength of the base material while providing enhanced friction characteristics for improved transverse load resistance.
2Strength
If the friction coefficient is increased with high-friction coatings, then the transverse load capacity is improved, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing complexity is managed by focusing the parameter change solely on the surface friction coefficient through coatings, rather than modifying the entire component geometry or material composition. This localized parameter change allows the use of established coating technologies (thermal spray, CVD, PVD, electroplating) that are already integrated into conventional manufacturing workflows.
Solution Approach 2:
The high-friction coatings are applied as relatively thin layers (typically 1-10 micrometers) that can be reapplied or replaced if worn, rather than requiring the entire chock component to be replaced. This approach treats the friction surface as a consumable or replaceable layer, reducing the economic impact of manufacturing complexity.

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 increased friction coefficient significantly improves the chock's resistance to horizontal movement, effectively increasing its transverse load capacity and ensuring better stability under mechanical loads.
