Anchor fitting for anchoring in a workpiece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring fittings require precise alignment and drilling of workpiece recesses, which can be challenging due to limited movement play and alignment transverse width, making them unsuitable for inexactly arranged holes.
Innovation Solution
The anchoring fitting features an insertion receptacle with an increased alignment transverse width, allowing for greater movement play and adjustable alignment, enabling the tie rod to be inserted and aligned correctly even in slightly misaligned workpiece recesses, with a clamping body that adjusts along a clamping axis perpendicular to the tie rod's longitudinal axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the insertion receptacle has a limited transverse width to ensure precise fitting, then the alignment precision is improved, but the adaptability to inexactly arranged workpiece recesses deteriorates
Solution Approach 1:
The patent changes the dimensional parameter of the insertion receptacle by providing a transverse width that is intentionally larger than the tie rod diameter. This parameter change allows the receptacle to accommodate alignment variations while maintaining secure engagement, resolving the contradiction between precision and adaptability.
Solution Approach 2:
The invention segments the engagement dimensions into two independent functional zones: the transverse width dimension for alignment accommodation and the longitudinal depth dimension for secure engagement. This segmentation allows each dimension to independently fulfill its specific function without compromising the other.
2Adaptability or versatility
If the insertion receptacle has a larger transverse width to accommodate alignment variations, then the adaptability to misaligned recesses is improved, but the manufacturing precision requirements worsen
Solution Approach 1:
The patent incorporates a dimensional buffer by making the insertion receptacle transverse width larger than the tie rod diameter. This buffer zone absorbs alignment variations and manufacturing tolerances before they can affect the engagement quality, effectively cushioning against precision issues.
3Stability of the object's composition
If the support surface extends perpendicularly to the tie rod axis for stable support, then the stability of the tie rod is improved, but the ease of insertion deteriorates due to reduced movement play
Solution Approach 1:
The invention segments the support function from the insertion function by providing multiple support surfaces at different locations and orientations. The perpendicular support surfaces provide stability during operation, while the enlarged transverse width provides movement play during insertion, allowing both functions to coexist without conflict.
