Constant Bearer Spring System with Rotatable Cam Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing constant bearers for loads, such as pipelines, face challenges in maintaining a constant carrying force over travel due to changes in prestress, leading to deviations from the desired spring force profile, which requires complex adjustments or replacement of components.
Innovation Solution
A correction device is integrated within the constant bearer to adjust the spring system by changing the spatial orientation of springs, allowing for automatic compensation of deviations in the carrying force profile without replacing components, by modifying the load and force points' positions relative to the cam part, thereby maintaining a constant carrying force over travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the prestress of the suspension system is changed to accommodate varying load conditions, then the adaptability of the constant bearer improves, but the spring characteristics change causing deviations from the desired constant carrying force profile
Solution Approach 1:
The cam disc is designed with a rotatable adjustment mechanism that allows the compensation profile to be dynamically changed. By rotating the cam disc to different angular positions, the constant bearer can adapt to different prestress conditions while maintaining the constant carrying force profile, resolving the contradiction between adaptability and reliability
Solution Approach 2:
The invention changes the angular position parameter of the cam disc to compensate for changes in prestress. This parameter adjustment allows the system to maintain optimal compensation characteristics across varying load conditions, ensuring the constant carrying force profile is preserved despite prestress variations
2Manufacturing precision
If a cam disc with specific geometry is designed for a preset prestress, then the compensation precision for that specific prestress improves, but the system becomes inflexible when prestress changes requiring component replacement
Solution Approach 1:
The cam disc is made rotatable with an adjustment mechanism that allows changing its angular position. This dynamic adjustment capability enables the same cam disc to provide precise compensation for different prestress values by rotating to the appropriate angular position, eliminating the need for component replacement and providing both precision and adaptability
Solution Approach 2:
The single cam disc is designed to perform multiple compensation functions for different prestress conditions through angular rotation. This multi-functional design allows one component to replace what would otherwise require multiple specialized components, providing both precision and versatility
3Manufacturing precision
If the relative position of the cam disc and circular disc is adjusted by rotation to reach the adjusting position, then the compensation accuracy improves, but the adjustment process becomes complicated and inconvenient
Solution Approach 1:
The adjustment mechanism is designed to be self-aligning, where the cam disc automatically rotates to its correct angular position based on the current prestress condition. This self-service feature eliminates the need for complex manual adjustment procedures while maintaining high compensation accuracy
Solution Approach 2:
The system incorporates feedback mechanisms that detect the current prestress level and automatically determine the required angular position of the cam disc. This feedback control simplifies the adjustment process by eliminating the need for manual calculation and precise positioning, while still achieving high compensation accuracy
