Square Retaining Base Connecting Body for Grid Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support frames with lattice structures have low storage density for rotationally symmetrical workpieces and require custom-made lattice structures with rectangular openings, leading to high costs due to the need for a rectangular connection mechanism.
Innovation Solution
A connecting body with a square retaining base and diametrically arranged clamping grooves that can be inserted into a square receiving opening and locked by rotating about a pitch circle angle, allowing for a detachable connection using a predetermined torque, enabling use in conventional square lattice structures and providing haptic feedback and anti-twist functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rectangular grid structure with spaced wire strands is used to form receiving openings, then the support frame has high inherent stability and dimensional stability, but the bearing density is low for rotationally symmetrical workpieces and custom-made structures are required
Solution Approach 1:
The connecting body uses a square retaining base instead of a circular one, matching the square geometry of the receiving openings in the grid structure. This asymmetric adaptation to the rectangular grid enables optimal space utilization and maximum bearing density for rotationally symmetrical workpieces while maintaining compatibility with the stable rectangular grid structure.
2Reliability
If connecting elements with retaining lugs are used that require 90° rotation for locking, then a secure connection is achieved, but the connecting elements cannot be used with conventional square grid structures and custom-made grid structures must be provided
Solution Approach 1:
The connecting body is designed with a square retaining base that can be universally inserted into any square receiving opening of conventional grid structures. The clamping grooves with radius of curvature and tangent enable locking at any angle (30°, 45°, 60°), making the connecting body compatible with standard square grid structures while maintaining secure connection, eliminating the need for custom-made structures.
3Stability of the object's composition
If the distance between wire strands in upper level is greater than in lower level to form rectangular receiving openings, then the grid structure provides stable receiving openings, but the surface area utilization is not optimal
Solution Approach 1:
The square retaining base of the connecting body is specifically adapted to match the square geometry of the receiving openings formed by the rectangular grid structure. This asymmetric design optimizes surface area utilization by perfectly fitting the available space in each receiving opening, maximizing the number of connecting bodies that can be mounted on the support frame while maintaining the stable rectangular grid structure.
