Support Base Connecting Plate with Angled Through-Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support bases have low load-bearing capacity, particularly under tension and torsion, due to screw connections that can fail when transferring wind forces to the ground.
Innovation Solution
The support base design features a connecting plate with parallel and inclined through-openings, allowing screws to cut multiple annual rings in a wooden stand, enhancing load-bearing capacity and resistance to torsion, and includes a height-adjustable mechanism with a threaded extension and cone receptacle for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional screw connections are used to attach the support base to the stand, then the assembly is simple to manufacture, but the load-bearing capacity is low and screws tear out under wind forces
Solution Approach 1:
The connecting plate is segmented into multiple functional zones with different through-opening configurations. First through-openings are arranged parallel to the stand axis for primary vertical load bearing, while second through-openings are arranged at angles to cut annual rings for enhanced tensile strength. This segmentation allows each opening type to address specific load components, collectively achieving high load-bearing capacity while maintaining a relatively simple manufacturing process.
2Strength
If screws are arranged to cut multiple annual rings in wooden stands, then the load-bearing capacity under tension increases, but the device complexity increases due to specialized through-opening configurations
Solution Approach 1:
Different regions of the connecting plate are assigned different through-opening characteristics optimized for specific functions. The first through-openings (parallel to stand axis) are optimized for compressive loads and simple insertion, while the second through-openings (angled to cut annual rings) are optimized for tensile loads. This local quality differentiation ensures that each opening type addresses the most critical load conditions in its specific zone, achieving high overall strength without requiring all openings to be complex.
Solution Approach 2:
The second through-openings are deliberately arranged asymmetrically at specific angles relative to the stand axis, designed to cut through annual rings in a pattern that maximizes tensile resistance. This asymmetric configuration, where openings are not uniformly distributed but strategically positioned, creates superior mechanical interlocking with the wooden stand's grain structure, enhancing tensile load-bearing capacity while adding only moderate geometric complexity.
3Reliability
If the support base is designed with high resistance to torsion and dynamic loads, then the reliability under wind forces improves, but the ease of operation for height adjustment decreases
Solution Approach 1:
The support base incorporates a height-adjustable mechanism that allows the connecting plate's position relative to the ground contact part to be dynamically changed. Threaded extensions with cone receptacles enable controlled movement and locking at different heights. This dynamic capability allows the structure to adapt to varying height requirements while the inclined through-opening configuration maintains high resistance to torsion and dynamic loads, achieving both reliability and operational flexibility.
