Helical Spring Line for High-Pressure Solid Media Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure devices for diamond synthesis suffer from complex and uneconomical handling due to the need to drain hydraulic oil to access the breeding chamber, leading to oil leaks, valve wear, and pressure imbalances, which result in misalignments and potential breakage of the internal stamp or rupture of materials.
Innovation Solution
A device with permanently connected pressure chambers via a helical spring line, eliminating the need for valves and moving parts, ensures consistent oil pressure and symmetrical movement of ball sectors, preventing misalignments and enhancing the quality of synthesis results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If valves with moving parts are used to prevent oil leakage when separating half-bodies, then oil leakage is reduced during operation, but valve wear causes pressure imbalance and misalignment of spherical sectors
Solution Approach 1:
The invention removes the valves with moving parts from the system entirely. Instead of using valves to control oil flow between pressure chambers, the design allows direct communication between chambers through the common parting line, eliminating the source of wear and pressure imbalance while maintaining sealing through the rigid structural connection of the half-bodies
Solution Approach 2:
The pressure chambers are segmented into multiple zones that can be independently controlled through the oil line connecting to both half-bodies. This segmentation allows precise pressure control in different regions without requiring valves at each chamber interface, using the single oil line connection to distribute pressure uniformly
2Ease of operation
If the oil line is interrupted when separating half-bodies to allow access, then the breeding chamber is accessible, but hydraulic oil leaks and handling becomes complex
Solution Approach 1:
The invention extracts the problematic valve components from the oil line system. The oil line is designed to remain continuous through the common parting line without interruption, eliminating the need for complex valve operations while maintaining full accessibility when half-bodies are separated. The oil simply flows through the open path without requiring active control
Solution Approach 2:
The common parting line serves as an intermediary structure that naturally connects the pressure chambers when half-bodies are joined and allows free access when separated. This intermediary geometry eliminates the need for active valve control, using the structural arrangement itself to manage oil flow and accessibility
3Reliability
If valves are used to maintain pressure seal, then pressure containment is improved, but pressure losses occur during pressure build-up and release
Solution Approach 1:
The invention removes all valves from the pressure control system. Pressure containment is achieved through the rigid structural connection of half-bodies and the geometry of the pressure chambers themselves, eliminating pressure losses associated with valve opening and closing operations. Pressure is built up and released directly through the oil line without intermediate control elements
Solution Approach 2:
The oil line provides continuous pressure transmission from the oil pump through both half-bodies to the breeding chamber without interruption. The pressure build-up and release processes are continuous actions without the start-stop nature imposed by valve operations, eliminating energy losses and maintaining consistent pressure throughout the system

The device (1) additionally comprises an opening and a channel (14) in the lower half-body (2), in order to connect an oil line from an oil pump to the device and to pump the oil into the pressure space between the lower half-body (2) and the elastic membrane (6) inserted in it. The pressure spaces (62, 73) in the lower half-body (2) and in the upper half-body (3) are connected by means of a line. The device (1) is distinguished by the fact that the line permanently connects the pressure spaces (62, 73) in the lower half-body (2) and in the upper half-body (3) to one another both in the opened state and in the closed state of the device. The device is also distinguished by the fact that it comprises a pipeline which runs outside the lower shell-shaped half-body (2) and the upper shell-shaped half-body (3) and takes the form of a helically coiled line (17).
