Timed Hydraulic Pressure Boost Control for Load Spikes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power boost control systems require manual activation of the boost mode each time it is needed, which is inconvenient and may limit working situations, especially when a large external load is applied, potentially damaging devices due to excessive pressure.
Innovation Solution
A time-based power boost control system that automatically controls the relief device to use a higher pressure level for a shorter boost-on time and a lower pressure level for a longer boost-off time, or sets a cumulative boost-on time limit, to prevent device damage and enhance operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual activation of boost mode is required each time, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The control device automatically detects when boost mode is needed and activates it without manual intervention. The system monitors operational conditions and self-regulates the relief pressure level, eliminating the need for manual activation while maintaining system simplicity
Solution Approach 2:
The control device continuously monitors system pressure and operational status, using this feedback to automatically determine when to activate or deactivate boost mode. This closed-loop control enables automatic operation while keeping the control logic relatively simple
2Productivity
If boost mode is activated to overcome large external load, then productivity is improved, but reliability deteriorates due to excessive pressure
Solution Approach 1:
The relief pressure level is made dynamic rather than fixed. The control device adjusts the relief pressure between a first level and a second level based on real-time operational needs, allowing the system to adapt to varying load conditions while preventing excessive pressure buildup that could damage components
Solution Approach 2:
The system changes the pressure parameter dynamically by switching between different relief pressure levels. When boost mode is activated, the relief pressure is increased to enable higher power output; when deactivated, it returns to the normal level to ensure component safety, thus balancing productivity and reliability
3Power
If boost-on time is extended to maintain high pressure, then power output is improved, but durability deteriorates
Solution Approach 1:
The control device implements periodic switching between boost mode and normal operation mode. By activating boost mode only for necessary time periods and then deactivating it, the system achieves the required power output while limiting the cumulative duration of high-pressure exposure, thereby protecting components from degradation
Solution Approach 2:
The system applies high pressure (excessive action) only when absolutely necessary to overcome large external loads, rather than maintaining it continuously. The control device carefully manages the duration and frequency of boost mode activation, using high power output partially and selectively, which maintains productivity while preventing excessive wear on components
Data Source
AI summary
A time-based power boost control system. A fluid source supplies fluid. A relief device relieves pressure of the fluid supplied by the fluid source when the pressure of the fluid exceeds a relief pressure level. A control device controls the relief device. When a boost mode in which at least a first level of pressure and a second level of pressure, higher than the first level of pressure, are allowed to be selectively used as the relief pressure level is active, a length of a boost-on time in which the second level of pressure is used as the relief pressure level is shorter than a preset maximum boost-on time limit, and a length of a succeeding boost-off time succeeding the boost-on time in which the first level of pressure is used as the relief pressure level is equal to or longer than a preset minimum boost-off time limit.
