Adjustable Shaker Platform Clamping for Mixed Container Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laboratory shaking devices struggle to securely fasten containers of varying sizes and shapes, leading to unwanted movement, damage, and contamination, with complex and cumbersome locking mechanisms that require access from multiple sides.
Innovation Solution
The shaking platform features adjustable holding rods that span only part of its length and width, allowing multiple container-receiving spaces with independent clamping, and a simplified locking mechanism accessible from above, using an adjusting rail and clamping knobs for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holding rods are designed to extend over the entire length or width of the shaking platform to fasten containers, then containers can be secured across the full platform area, but containers of different sizes cannot be accommodated and containers may come loose during operation
Solution Approach 1:
The shaking platform is divided into multiple independent container-receiving spaces, each with its own holding rods. This segmentation allows each space to be independently adjusted for different container sizes while maintaining secure fixation. The platform surface is divided into several regions, each capable of accommodating containers of varying dimensions without affecting others.
Solution Approach 2:
The holding rods are designed to be adjustable in position and distance from one another, allowing dynamic adaptation to different container sizes and shapes. The adjusting rails enable the holding rods to be repositioned along the platform, providing flexibility to securely fasten containers of various dimensions while maintaining reliable fixation during shaking operations.
2Reliability
If conventional locking mechanisms are used to secure holding rods, then containers can be fixed in place, but the locking mechanisms require access from multiple sides and are complex and cumbersome to operate
Solution Approach 1:
Instead of requiring lateral access to lock the holding rods as in conventional designs, the locking mechanism is inverted to allow operation from above. The clamping knobs are positioned on the upper side of the platform, enabling users to easily secure or release holding rods by simply reaching over the platform, dramatically improving accessibility and ease of operation.
Solution Approach 2:
The locking mechanism is designed to be self-contained and operable from a single direction (above the platform). The clamping knobs with integrated locking functionality allow users to independently secure each holding rod without requiring assistance or access from multiple sides, making the system self-sufficient and easier to operate.
