Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable chocks do not allow for sliding of the supported equipment, which is necessary to accommodate deformations due to temperature and pressure variations, and their installation is hindered by curing processes.
Innovation Solution
An adjustable chock kit with a sliding element having a lower friction coefficient, allowing for easy installation and accommodating equipment deformations, featuring a stainless-steel plate and a sliding element with a roughness average Ra less than 0.8 μm to reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sliding element with lower friction coefficient is added to enable equipment sliding, then the ability to accommodate deformations is improved, but the device complexity increases
Solution Approach 1:
The chock is divided into multiple components: a first component (base), a second component (adjustable element), and a sliding element. This segmentation allows each component to have specific functions - the first component provides structural support, the second component enables height adjustment, and the sliding element facilitates deformation accommodation, thereby resolving the contradiction by making the complex functionality manageable through modular design.
Solution Approach 2:
The sliding element acts as an intermediary between the first component and the supported equipment. It mediates the interaction by providing a low-friction interface that allows controlled sliding while still maintaining support functionality. This intermediary approach enables the chock to accommodate deformations without requiring complete redesign of the entire support system.
2Loss of time
If adjustable chocks are used instead of grout or epoxy resin, then installation time is reduced and operational activities are not limited, but the ability to allow equipment sliding is lost
Solution Approach 1:
The chock incorporates a sliding element that introduces dynamic capability to an otherwise static support device. This sliding element allows the chock to transition from a fixed position to a movable state, enabling it to accommodate thermal and pressure deformations dynamically while maintaining the quick-installation advantage of mechanical chocks over curing-based solutions.
Solution Approach 2:
The chock combines different materials with complementary properties: the first and second components provide structural strength and adjustability, while the sliding element (made of materials with low friction coefficients) provides sliding capability. This composite approach integrates multiple functions within a single device, resolving the contradiction between quick installation and sliding capability.
3Adaptability or versatility
If the sliding element has a very smooth surface (Ra < 0.8 μm) to reduce friction, then the sliding capability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a quantitative parameter for surface roughness (Ra < 0.8 μm) to optimize the sliding capability. This parameter change approach allows for objective quality control and standardized manufacturing processes. By defining a specific roughness threshold, the patent balances the need for low friction with practical manufacturing capabilities, avoiding excessively stringent requirements while ensuring adequate sliding performance.
