Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dimensional deviations and inaccuracies occur during production and assembly, then manufacturing flexibility is improved, but sealing reliability deteriorates leading to leaks and increased material stress
Solution Approach 1:
The patent applies parameter changes by providing adjustment mechanisms that allow the sealing device to adapt to dimensional variations. The fastening means can be positioned at different locations on the positioning element, and the sealing device can be adjusted in its mounting position, enabling the system to accommodate manufacturing tolerances while maintaining reliable sealing performance.
Solution Approach 2:
The positioning element serves as an intermediary between the hull and the boat drive assembly. It provides a reference structure that mediates the connection, allowing precise positioning of fastening means and sealing devices while compensating for dimensional deviations in the individual components.
2Manufacturing precision
If dimensional deviations occur during production and assembly, then manufacturing tolerance range is improved, but service life deteriorates due to increased material stress
Solution Approach 1:
The adjustment mechanisms allow the sealing device and fastening means to be repositioned to accommodate dimensional variations, preventing excessive stress on sealing elements and fastening components. This extends the service life by ensuring that components operate within their designed stress parameters despite manufacturing tolerances.
Solution Approach 2:
The positioning element with multiple positioning possibilities provides a buffer against dimensional deviations before they can cause damage. By allowing adjustment within a range of positions, the system cushions the sealing elements and fastening means from excessive stress that would otherwise occur due to manufacturing tolerances.
3Ease of manufacture
If inaccurate transitions and gaps occur on the outside of the hull, then assembly flexibility is improved, but flow behavior deteriorates leading to unfavorable hydrodynamics
Solution Approach 1:
The positioning element allows adjustment of the sealing device and cover positions to achieve accurate transitions and minimize gaps. By enabling positional adjustments, the system can accommodate assembly flexibility while maintaining smooth external surfaces that favorably affect flow behavior.
Solution Approach 2:
The patent applies local quality by ensuring that the external surface transitions are precisely controlled at critical locations. The cover and sealing device can be positioned to create smooth, continuous surfaces in areas where flow behavior is most sensitive, while allowing more flexibility in other areas.
