Spring Tensioner Pressure Plate Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring tensioners require multiple interchangeable sets of differently designed support elements to clamp variously configured spring shock absorber struts, leading to stress on gripper elements due to diameter changes and limited adaptability to differently dimensioned coil springs, with a risk of slipping and uncertainty in extreme situations.
Innovation Solution
A spring tensioner design featuring a pressure plate that securely connects and stabilizes the holding elements via screw connections, allowing for adjustable alignment and engagement with the upper spring plate, and an optional pressure ring for precise angular adjustment, enabling adaptation to various spring plate geometries without needing multiple sets of holding elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interchangeable sets of differently designed support elements are provided to clamp variously configured spring shock absorber struts, then adaptability to differently dimensioned coil springs is improved, but device complexity increases and the risk of slipping occurs due to stress on gripper elements from diameter changes
Solution Approach 1:
The pressure plate is designed with a universal interface that can accommodate various spring configurations through a single standardized component. The holding elements are configured to work with the pressure plate across different spring types, eliminating the need for multiple specialized support element sets while maintaining adaptability to differently dimensioned coil springs
Solution Approach 2:
The support element is divided into modular components: holding elements, connecting elements, and a pressure plate. This segmentation allows the pressure plate to serve as a standardized interface that can work with various holding element configurations, reducing the need for complete interchangeable sets while maintaining versatility
2Ease of operation
If gripper elements are designed to engage with spring coils, then the ability to tension helical springs is improved, but stress on gripper elements increases due to diameter changes during tensioning and relaxation
Solution Approach 1:
The pressure plate serves as an intermediary component between the holding elements and the spring assembly. It distributes and stabilizes the engagement forces, reducing stress concentrations on the gripper elements during tensioning and relaxation cycles while maintaining the ability to effectively tension helical springs
Solution Approach 2:
The pressure plate is positioned to provide preliminary stabilization and force distribution before the full tensioning load is applied to the gripper elements. This pre-cushioning effect reduces the peak stress on the gripper elements during the tensioning cycle
3Adaptability or versatility
If holding elements are made adjustable relative to the actuator, then adaptability to different spring configurations is improved, but reliability decreases in extreme situations due to potential unintended movement or slipping
Solution Approach 1:
The holding elements are designed with controlled adjustability that allows dynamic adaptation to different spring configurations while maintaining stable engagement. The adjustment mechanism provides flexibility during setup but ensures fixed, reliable positioning during operation, preventing unintended movement even in extreme situations
Solution Approach 2:
The pressure plate acts as a stabilizing intermediary that secures the adjustable holding elements in their positioned state. It provides additional contact points and force distribution that prevent slipping, ensuring reliability in extreme situations while preserving the adaptability benefits of adjustable holding elements

AI summary
The compressor has an actuator actuated for varying distance between supporting elements for tensioning a helical spring or a spring damper. One of the supporting elements includes two holding elements that are engaged with an upper spring plate and/or a spring coil of the spring. The holding elements are connected with the actuator relative to each other, and a pressure plate (1) axially supports the holding elements at the plate and is detachably connected with the holding elements. The pressure plate is engaged with the plate.
