Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the hydrogen storage component is subjected to high pressure to increase hydrogen storage capacity, then the hydrogen storage capacity is improved, but the vessel portion may undergo plastic deformation
Solution Approach 1:
The patent applies parameter changes by operating the hydrogen storage component at controlled temperatures and pressures within the safe operating window of the vessel portion. The system utilizes the temperature-pressure phase diagram of the hydrogen storage material to identify optimal operating conditions that maximize hydrogen capacity while maintaining vessel integrity, avoiding plastic deformation by staying within material limits.
Solution Approach 2:
The patent employs composite materials by combining the hydrogen storage component (containing hydrogen-absorbing material) with the vessel portion (made of high-strength material) in a nested configuration. This composite structure allows the vessel to withstand high pressures while the inner component handles hydrogen absorption, distributing mechanical and chemical functions across different materials.
2Productivity
If the hydrogen storage component is heated to facilitate hydrogen desorption, then the hydrogen release rate is improved, but heat management becomes more challenging
Solution Approach 1:
The patent introduces a tempering fluid as an intermediary substance that circulates through channels in the vessel portion. This fluid acts as a heat transfer mediator, absorbing excess heat during hydrogen absorption (exothermic) and releasing heat during hydrogen desorption (endothermic), thereby enabling temperature-controlled hydrogen release without direct heating of the storage component.
Solution Approach 2:
The patent replaces direct mechanical heating systems with a thermal management system using circulating tempering fluid. Instead of applying external heat sources, the system uses the natural heat exchange between the tempering fluid and the hydrogen storage component to control the endothermic desorption process, substituting mechanical heating control with fluid-based thermal management.
3Strength
If the vessel portion is made from high-strength material to withstand high pressure, then the mechanical strength is improved, but the thermal conductivity may be reduced
Solution Approach 1:
The patent introduces a tempering fluid as a thermal intermediary that circulates through channels in the vessel portion. This fluid serves as a heat transfer medium, compensating for any thermal conductivity limitations of the high-strength vessel material by providing active convection-based heat transfer between the hydrogen storage component and the external environment.
Solution Approach 2:
The patent employs hydraulic principles by using a circulating liquid tempering fluid to transfer heat. The fluid flows through channels in the vessel portion, utilizing convection and conduction mechanisms to efficiently manage thermal loads, thereby overcoming potential thermal conductivity constraints of high-strength materials through fluid-based thermal management.
