Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple layers of packaging film are provided for externally wrapping the flexible freight bag, then the battery powder is protected from rainwater, but the device complexity and packaging volume increase
Solution Approach 1:
The patent combines the rain protection function and the hydrogen absorption function into a single integrated packaging container. The container body serves as both the rain barrier and the housing for the gas-suction member with hydrogen-absorbing material, eliminating the need for separate packaging films and reducing overall packaging complexity.
Solution Approach 2:
The packaging container is designed to perform multiple functions simultaneously: it provides mechanical protection against rainwater, actively absorbs generated hydrogen gas through the gas-suction member, and maintains structural integrity during transportation. This multi-functional design reduces the number of separate components needed.
2Productivity
If the gas-suction member is made elastic to enable automatic hydrogen absorption through elastic vibration, then the hydrogen removal efficiency is improved, but the device complexity increases
Solution Approach 1:
The gas-suction member is designed with elastic properties that allow it to dynamically respond to pressure changes inside the container. As hydrogen accumulates and increases internal pressure, the elastic member deforms and vibrates, actively drawing gas into the absorption chamber. This dynamic behavior enables automatic hydrogen removal without external power sources or complex control systems.
Solution Approach 2:
The elastic gas-suction member is self-actuating, using the hydrogen pressure buildup itself as the driving force for gas absorption. The system serves itself by converting the harmful pressure increase into the mechanical energy needed for gas suction, eliminating the need for external actuators, sensors, or control mechanisms.
3Reliability
If check valves are installed to prevent gas leakage and improve suction efficiency, then the hydrogen absorption effectiveness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The check valve function is extracted as a separate, simple component integrated into the gas-suction member assembly. By isolating the one-way valve function from the main container structure, the design achieves reliable gas flow control while keeping the overall manufacturing process relatively simple and the valve placement straightforward.
4Reliability
If a filter assembly is added to filter impurities from the sucked gas, then the gas absorbent efficiency is improved, but the device complexity increases
Solution Approach 1:
The filter assembly is nested within the gas-suction member structure, with the filter element positioned inside the hollow chamber. This nested arrangement allows the filter to be integrated into the existing gas flow path without requiring separate external filtration systems, reducing overall structural complexity while maintaining effective impurity removal before gas contacts the absorbent material.

AI summary
A gas absorption box includes a box body, at least one gas absorption member and an outer housing assembly, the box body has an accommodating cavity; the gas absorption member is elastic and is provided with a first inner cavity, and the first inner cavity is in communication with the outside of the box body; and the outer housing assembly is arranged in the accommodating cavity and is elastically connected to the box body, and the outer housing assembly has a second inner cavity for accommodating a gas absorbent, the second inner cavity being in communication with the first inner cavity, and the gas absorption member being capable of absorbing gas for the second inner cavity. When battery powder or some positive-electrode materials for batteries are transported, hydrogen generated by the battery powder or some positive-electrode materials for batteries gathers towards the upper portion of a ton bag.
