Adjustable Anchoring Connection for Precise Wooden Component Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for connecting wooden components in high-load applications face challenges in achieving precise assembly and accommodating manufacturing tolerances, leading to potential misalignment and increased assembly time due to the inability to adjust the screw-in depth after initial assembly.
Innovation Solution
The device features anchoring elements with an adjustable mechanism accessible from below, allowing for post-assembly adjustment of the second component relative to the first, ensuring high connection accuracy and enabling the transmission of significant tensile and transverse forces through a coaxial support and guide section with bores and conical surfaces, facilitating precise positioning and secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the screw-in depth of the retaining screw is fixed before assembly, then the assembly process is simplified, but manufacturing tolerances cannot be compensated leading to misalignment and connection inaccuracies
Solution Approach 1:
The retaining screw is designed with a threaded bore allowing dynamic adjustment of screw-in depth after assembly. The second component can be rotated relative to the first component to achieve precise alignment by adjusting the screw-in depth of the retaining screw, transforming a static fixed-depth design into a dynamic adjustable one.
Solution Approach 2:
The invention allows changing the screw-in depth parameter of the retaining screw after assembly. The threaded bore in the retaining screw enables variation of the engagement depth to compensate for manufacturing tolerances and achieve optimal connection accuracy between components.
2Ease of operation
If the retaining screw is made accessible from above, then initial assembly is easier, but post-assembly adjustment for tolerance compensation is impossible
Solution Approach 1:
The adjusting means is positioned at the bottom of the first component, providing access from a different spatial dimension (below rather than above). This allows the retaining screw to be accessible during initial assembly from above while enabling post-assembly adjustment from below, effectively utilizing vertical space for dual-purpose access.
Solution Approach 2:
The threaded bore in the retaining screw acts as an intermediary mechanism. It allows the retaining screw to be initially accessible from above for assembly while providing a pathway for adjustment from below after assembly, mediating between the two conflicting accessibility requirements.
3Productivity
If the screw-in depth is too small to ensure proper hanging, then assembly is straightforward, but play occurs between carrier plate and retaining screw reducing connection stability
Solution Approach 1:
The adjustable screw-in depth mechanism allows the connection to transition from a fixed state to a dynamically optimizable state. After assembly, the screw-in depth can be increased to eliminate play and achieve optimal connection stability without compromising the straightforward initial assembly process.
4Stability of the object's composition
If the screw-in depth is increased to eliminate play, then connection stability improves, but the retaining screw may become inaccessible for assembly
Solution Approach 1:
By positioning the adjusting means at the bottom of the first component, the invention enables access from a different dimension. This allows the retaining screw to be assembled from above while adjustment for optimal depth occurs from below, resolving the accessibility conflict.
