Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional magnetic cushioning structures with electromagnets and mechanical springs are used, then magnetic cushioning is provided, but horizontal vibration isolation is ineffective and device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical springs and complex electromagnet assemblies with a MagLev module using permanent magnets and magnetic repulsion forces. This substitution eliminates mechanical contact points that fail to isolate horizontal vibrations, while the magnetic field inherently provides isolation in all directions including horizontal, thereby resolving the contradiction between vibration isolation effectiveness and device complexity
Solution Approach 2:
The patent changes the fundamental parameter from mechanical spring stiffness to magnetic repulsion force by using opposing permanent magnets with like polarity. This parameter change enables the system to provide effective horizontal vibration isolation through the non-contact magnetic field, while reducing overall device complexity by eliminating mechanical spring components and complex mounting structures
2Ease of operation
If magnetic cushioning systems with aligned magnet sheets are used, then magnetic support is provided, but sidewise movement freedom is limited by mechanical mounting structure
Solution Approach 1:
The patent replaces rigid mechanical mounting structures that constrain sidewise movement with a MagLev module suspended by flexible elements. The magnetic repulsion provides support without mechanical contact, allowing natural sidewise movement and swinging motion while maintaining vertical support, thus resolving the contradiction between movement freedom and structural support
3Adaptability or versatility
If adjustable firmness magnetic cushioning systems are used, then firmness adjustment is provided, but manufacturing cost increases due to multiple coil-like units
Solution Approach 1:
The patent achieves adjustable firmness by changing the magnetic field parameters through an electromagnet that can vary its magnetic strength, rather than using multiple discrete coil-like units. By controlling the current to the electromagnet, the magnetic repulsion force can be adjusted continuously, providing firmness control while simplifying manufacturing and reducing costs
Solution Approach 2:
The electromagnet serves multiple functions: it provides the primary magnetic repulsion force for support, enables firmness adjustment through variable current control, and can interact with the permanent magnet for horizontal swing control. This multi-functionality eliminates the need for separate components, reducing manufacturing complexity and cost while maintaining adaptability
4Strength
If heavy-duty MagLev modules are mounted on vessel hulls for ice protection, then impact protection is provided, but system cost and complexity increase
Solution Approach 1:
The patent applies MagLev modules to the vessel hull before ice impact occurs, creating a pre-positioned magnetic cushioning layer. The permanent magnets in the modules generate repulsive forces that cushion against incoming ice, absorbing impact energy before it reaches the hull. This beforehand cushioning provides strong impact protection while maintaining relatively simple system architecture compared to active reinforcement systems

AI summary
The present invention relates to a innovative magnetic tension lock(MTL) control system which guides the MagLev module in both vertical and horizontal movement. The MagLev module moves on its inherent magnetic force and is guided by the MTL control system. The MagLev module with MTL control system can be used in products of various applications. It can be made at efficient cost to perform unique function. It can provide magnetic cushioning, which is great for seat, bed and other body-supporting furniture. It can also be applied as a cushioning layer against outside impact, thus it can be mounted onto the surface of heavy duty equipment or even the vessel sailing in icy water. It functions on its magnetic energy for load capacity and only requires compact battery power for its MTL control system. Thus it saves energy and reduces impact on the environment. It can replace the traditional MagLev module that runs on electricity otherwise.
