Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional circuit boards or chips are mounted across the entire surface of the main circuit board to implement smart functions, then the medical fluid pump gains smart features, but the main circuit board becomes larger and the pump dimensions increase
Solution Approach 1:
The communication board is arranged perpendicular to the main circuit board, transitioning from a planar layout to a three-dimensional configuration. This vertical arrangement allows the communication board to be mounted on the side surface of the main board, significantly reducing the projected area occupied on the main circuit board while accommodating the communication module's space requirements.
Solution Approach 2:
The communication board is enclosed within a shielding cage that is integrated with the housing structure. This nesting approach allows the communication module to be housed within the existing pump structure without requiring additional external space, effectively nesting the communication functionality within the compact pump body.
2Adaptability or versatility
If the main circuit board is made larger to accommodate smart functions, then more smart features can be implemented, but the pump's accessibility for medical personnel is reduced
Solution Approach 1:
By arranging the communication board perpendicular to the main circuit board, the patent reduces the footprint on the main board, thereby maintaining the compact dimensions of the pump and ensuring accessibility for medical personnel during patient treatment.
3Area of stationary object
If smart functions are implemented directly on the motherboard, then the required size is reduced, but the cost of the motherboard significantly increases and replacement is required if functions fail
Solution Approach 1:
The patent separates the communication module onto an independent communication board that can be mounted perpendicular to the main circuit board. This segmentation allows the communication functionality to be implemented as a separate, replaceable component rather than integrating it directly into the motherboard, reducing manufacturing costs and enabling selective replacement.
Solution Approach 2:
The communication board is extracted as a separate component from the main circuit board, allowing it to be independently manufactured, tested, and replaced. This extraction reduces the complexity and cost of the main motherboard while enabling modular maintenance.
4Area of stationary object
If the number of smart features is limited to counteract space increase, then installation space is reduced, but various smart features are eliminated
Solution Approach 1:
The perpendicular arrangement of the communication board enables the system to accommodate smart features without increasing the pump's footprint, as the communication board utilizes vertical space rather than horizontal space on the main circuit board.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design maintains compact dimensions, ensures effective cooling and electromagnetic stability, and allows for independent operation of the communication module, enabling wireless control and data transmission without increasing the pump's size or cost, while maintaining essential functions.
Implementation Method 1
The communication board (10) is enclosed by a metallic shielding cage (12)
Implementation Method 2
the orthogonal orientation of the communication board to the main board allows air to circulate more effectively around it than in the case of a planar/parallel orientation. This improves the cooling of the communication board.
