Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If high pressure of 6000 to 10,000 bar is applied during treatment, then the preservation effect is achieved, but triaxial deformation and leakage occur in the holding frame, high-pressure vessel, closures, and seals
Solution Approach 1:
The force transmission device is divided into multiple semicircular disks arranged side by side, with each disk independently supporting the closure plug. This segmentation allows the high pressure forces to be distributed across multiple separate load-bearing elements, preventing concentration of stress that would cause triaxial deformation and leakage in single-piece structures.
Solution Approach 2:
Semicircular disks with curved surfaces are used instead of flat or angular structures. The rounded geometry of the semicircular disks better distributes the high pressure loads and reduces stress concentration points, preventing plastic deformation and maintaining sealing integrity under 6000-10,000 bar treatment pressures.
2Strength
If massive design of load-bearing parts is used, then strength is improved, but the holding frame and components still undergo triaxial deformation under extreme pressure
Solution Approach 1:
The load-bearing structure is segmented into multiple semicircular disks that independently bear axial forces. This segmentation allows each component to be optimized for its specific load path, improving overall structural strength while reducing cumulative deformation through the distribution of stresses across multiple discrete elements rather than a single massive component.
Solution Approach 2:
The force transmission device combines semicircular disks made of pressure-resistant material with sealing elements, creating a composite structure that simultaneously provides high load-bearing capacity and resistance to deformation. The combination of structural and sealing materials in one integrated component prevents both mechanical failure and leakage under extreme pressure.
3Ease of operation
If conventional closure support devices are used, then the closure can be held, but plastic deformation and leakage arise under high pressure
Solution Approach 1:
The semicircular disks with curved surfaces provide superior deformation control compared to conventional flat support structures. The geometry of the semicircular disks naturally distributes contact stresses and prevents concentration at sharp edges or flat surfaces, maintaining manufacturing precision and preventing plastic deformation even under 10,000 bar treatment pressures.
Solution Approach 2:
The semicircular disks act as intermediary elements between the closure plugs and the holding frame. These disks mediate the transmission of high pressure forces, distributing the loads evenly and preventing direct contact between the closure and potentially deforming structures, thereby maintaining both ease of operation and dimensional stability.

AI summary
A device for high-pressure treatment of goods in a sealable high-pressure chamber may include a holding frame that holds the high-pressure chamber during pressurization, a closure having a sealing plug for sealing the high-pressure chamber, a hydraulic drive for moving the closure relative to the pressure chamber, and a support device that is movable between an end face of the high-pressure chamber and the holding frame and transmits force between the closure and the holding frame during pressurization. Axial forces acting on the sealing plug from the pressure may be absorbed by a force-transmission device configured as a semicircular disk. The semicircular disk may have an end face that faces the high-pressure chamber and a holder for a hydraulic cylinder. The semicircular disk may form a part of the outer shell of the hydraulic cylinder bearing the hydraulic pressure.
