Stacking Storage Upright Clamp Joint for Stable Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking storage arrangements face challenges in ensuring stable alignment and simplified assembly of uprights with respect to the frame assembly, often requiring complex post-processing and multiple joining elements.
Innovation Solution
A connecting device that bridges the angle between the frame assembly and upright, utilizing a clamping mechanism and dovetail profiles, allows for easy assembly and secure attachment without needing to guide joining elements through bores, and can be produced with zinc or aluminum die casting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional joining elements are used to connect uprights to frame assembly, then connection stability is achieved, but assembly complexity increases and post-processing is required
Solution Approach 1:
The connecting device merges multiple functions into a single integrated component: it provides clamping force against the frame assembly, creates a triangular rigid structure for stability, and eliminates the need for separate joining elements. The connecting device itself forms the structural triangle with the frame assembly and upright, combining connection and stabilization functions.
Solution Approach 2:
The invention extracts and eliminates the need for complex joining elements and post-processing operations. By using a clamping mechanism that directly engages with the frame assembly, the design removes unnecessary intermediate components and simplifies the assembly process while maintaining connection reliability.
2Strength
If multiple joining elements and bores are used, then connection strength is ensured, but manufacturing complexity increases
Solution Approach 1:
The connecting device is designed as a segmented clamping mechanism with two connecting elements that can engage with the frame assembly at different locations. This segmentation allows the clamping force to be distributed and applied effectively without requiring complex integrated structures, simplifying manufacturing while maintaining connection strength.
Solution Approach 2:
The invention changes the connection parameter from rigid fixed joints (requiring precise bores and multiple joining elements) to a clamping mechanism with adjustable engagement. The clamping force and engagement points can be optimized without requiring precise pre-drilled holes, simplifying the manufacturing process while ensuring adequate connection strength.
3Manufacturing precision
If complex post-processing is required, then precise alignment is achieved, but production time increases
Solution Approach 1:
The connecting device is designed with preliminary alignment features built into its structure. The clamping mechanism and connecting elements are pre-configured to engage with the frame assembly in a way that automatically ensures proper alignment, eliminating the need for time-consuming post-processing operations while maintaining manufacturing precision.
