Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional single-point thread interface is used for silencer mounting, then the mounting process is simple, but the attachment is slow and cumbersome, and requires precise orientation which increases installation time
Solution Approach 1:
The single continuous thread is divided into multiple discrete thread segments positioned at different axial locations. Each segment can engage independently, allowing the silencer to be mounted by rotating it into alignment with any of the multiple thread segments, thereby reducing installation time and eliminating the need for precise orientation.
Solution Approach 2:
The multiple thread segments provide multiple mounting orientations, making the interface universal and adaptable to different silencer positions. The system can accommodate silencers mounted at various angles, providing versatility and eliminating the need for precise alignment during installation.
2Reliability
If the Browning type tilt locking system is used, then the pistol functions reliably without a silencer, but the silencer weight is limited to 3-5.8 ounces before disabling the tilt locking function
Solution Approach 1:
The mounting interface is segmented into multiple discrete thread sections that distribute the mechanical load across multiple engagement points. This segmentation allows the system to handle greater silencer weights without compromising the tilt locking function, as the load is not concentrated at a single thread point.
Solution Approach 2:
The invention combines the tilt locking mechanism with a multi-segment thread interface that provides additional mechanical support. This merging of functions allows the pistol to maintain reliable tilt locking while supporting heavier silencers, as the multiple thread segments work together to distribute and manage the additional weight.
3Adaptability or versatility
If a single continuous thread is interrupted to create mounting segments, then multiple mounting orientations are enabled, but the thread structure becomes complex and manufacturing becomes more difficult
Solution Approach 1:
The thread structure is segmented into discrete, separate sections that can be manufactured independently. This segmentation simplifies manufacturing compared to creating a single complex interrupted thread, as each segment can be cut or formed separately and then assembled into the final mounting interface.
Solution Approach 2:
Each thread segment is positioned and dimensioned to provide specific mounting capabilities at different axial locations. The local quality of each segment is optimized for its specific function, allowing for versatile mounting orientations while keeping each individual segment relatively simple in structure.
4Reliability
If conventional thread mounting is used, then the attachment process is straightforward, but the mounting is not secure and can be affected by vibration and temperature changes
Solution Approach 1:
Multiple discrete thread segments provide multiple engagement points that work together to secure the silencer more reliably than a single thread. The segmented structure distributes vibrational and thermal stresses across multiple points, preventing loosening while maintaining ease of attachment through simple rotational engagement.
Solution Approach 2:
The invention merges multiple thread segments with a tapered bore and shoulder surfaces to create a composite mounting system. This combination provides both the simplicity of rotational attachment and the security of multi-point engagement, as well as mechanical sealing that prevents vibration and temperature-induced loosening.
