Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three clamping jaws are used in the clamping jaw assembly, then the clamping range is improved, but the structure becomes complicated and the cost increases
Solution Approach 1:
The patent combines multiple clamping functions into a single clamping jaw by designing grooves and protrusions on its inner surface. The groove forms a clamping cavity that can accommodate different drill bit sizes, while protrusions provide additional clamping points. This merging of functions allows one jaw to replace what would traditionally require multiple jaws, reducing structural complexity while maintaining clamping range.
Solution Approach 2:
The inner surface of the clamping jaw is segmented into multiple functional zones: grooves that form clamping cavities, protrusions that create additional clamping points, and smooth surfaces. This segmentation allows the single jaw to provide multiple clamping interfaces, effectively increasing the clamping range without adding more jaws to the assembly.
2Adaptability or versatility
If three clamping jaws are used in the clamping jaw assembly, then the clamping range is improved, but the operation convenience deteriorates
Solution Approach 1:
By merging multiple clamping functions into a single jaw, the patent reduces the number of components the operator must handle. The integrated design with grooves and protrusions allows one jaw to perform what would traditionally require multiple jaws, simplifying the loading and adjustment process while maintaining adaptability to different drill bit sizes.
3Adaptability or versatility
If three clamping jaws are used in the clamping jaw assembly, then the clamping range is improved, but the material waste increases and production cost rises
Solution Approach 1:
The patent merges the functions of multiple clamping jaws into a single jaw, reducing the total amount of material required. By designing the inner surface with grooves and protrusions that create multiple clamping interfaces, the single jaw can replace multiple separate components, thereby reducing material consumption and production costs while maintaining the ability to clamp different drill bit sizes.
4Device complexity
If traditional clamping jaw design is used, then the structure is simple, but the clamping effect deteriorates
Solution Approach 1:
The patent applies local quality by designing specific features on the inner surface of the clamping jaw. The grooves create localized clamping cavities, while protrusions provide localized clamping points. These localized features concentrate the clamping force at specific areas, improving the overall clamping effect without requiring a completely complex structure. The smooth surfaces between these features provide additional contact areas for stable clamping.
