Innovation Solution

The system incorporates a cooling mechanism with an inner circuit for each container disc to manage temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If natural convection cooling is used for the rotating brake disc, then the system structure remains simple, but the cooling efficiency is insufficient leading to overheating
Solution Approach 1:
The cooling system is segmented into multiple independent channels: natural convection channels in the brake disc, and forced circulation channels in the container discs. This segmentation allows each component to contribute differently to cooling, with the container discs providing active cooling while the brake disc maintains structural simplicity.
Solution Approach 2:
The container discs act as intermediary cooling elements between the brake disc and the cooling fluid. They are positioned to receive cooling fluid through channels and transfer the cooling effect to the brake disc assembly, thereby enhancing overall cooling efficiency without directly modifying the brake disc structure.

If brake pads are moved axially to increase friction and braking capacity, then braking efficiency improves, but wear on pads and disc increases due to intermittent friction
Solution Approach 1:
The brake pads are designed with axial movement capability, allowing them to dynamically adjust their position relative to the brake disc. This dynamic adjustment enables optimal friction contact during braking while reducing wear through controlled movement patterns that prevent continuous intermittent friction.
Solution Approach 2:
The system changes the friction parameter by controlling the axial movement of brake pads. During braking, the pads are positioned to maximize friction contact with the disc, while during non-braking periods, they are repositioned to minimize wear, thereby optimizing both braking capacity and service life.
3Temperature
If a single container disc is used for cooling, then the device complexity is reduced, but the cooling capacity and heat evacuation efficiency are insufficient
Solution Approach 1:
The cooling function is segmented across multiple container discs, each with its own cooling channels and fluid circulation paths. This segmentation increases the total cooling surface area and heat evacuation capacity while distributing the thermal load across multiple components.
Solution Approach 2:
Multiple container discs are merged into a single integrated cooling assembly that works in conjunction with the brake disc. The combined cooling capacity of multiple discs provides enhanced heat evacuation efficiency while maintaining a unified structural design.
Applied Scientific Principles
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 solution significantly improves braking efficiency by increasing friction and reducing wear on components, while the cooling system ensures thermal stability, extending the lifespan of brake components.
Implementation Method 1
each one of them comprises an inner circuit configured to accommodate the passage or flow of a coolant configured to cool it, reducing the temperature which can be reached by friction with the lining
Implementation Method 2
When the first container disc, as it is moved, makes contact with said first lining, it exerts a pressure on the surface thereof which generates a friction and, therefore, the braking of the supporting disc

AI summary
A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.
