Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laboratory tripods require separate scales for accurate dosing and weighing of substances during processing, which can be cumbersome and inefficient, especially when dealing with multiple substances or ongoing evaporation operations.
Innovation Solution
Integration of support projections on the tripod's ground support that are adjustable and connected to a weighing device, allowing for in-place weighing of vessels and their contents without the need for additional scales, enabling precise and immediate detection of weight changes during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate scales are used for weighing substances during processing, then weighing can be performed, but the operation becomes cumbersome and inefficient
Solution Approach 1:
The patent combines the weighing function with the tripod support structure by integrating support projections that are movable relative to the support surface and connected to a weighing device. This merging eliminates the need for separate scales, allowing vessels to be weighed directly on the tripod while processing, thereby improving ease of operation and reducing equipment complexity.
Solution Approach 2:
The tripod is designed with multi-functionality by incorporating both support and weighing functions into a single device. The support projections serve dual purposes: providing mechanical support for vessels and enabling weight measurement through connection to the weighing device, thus eliminating the need for dedicated weighing equipment.
2Productivity
If separate scales are used for dosing substances, then dosing can be performed, but the processing time increases due to repeated refilling and weighing
Solution Approach 1:
The integrated weighing function allows for continuous monitoring of substance weight during processing operations. The movable support projections maintain constant contact with the weighing device, enabling real-time weight detection without interrupting processing, thus eliminating time losses associated with removing vessels for separate weighing and refilling operations.
Solution Approach 2:
The weighing device provides immediate feedback on the weight of substances in vessels through the movable support projections. This real-time feedback enables operators to monitor dosing progress continuously and make adjustments without removing vessels from the tripod, significantly reducing the time required for dosing operations and improving overall productivity.
3Measurement precision
If conventional tripods are used without integrated weighing, then the structure remains simple, but weight changes during processing cannot be detected in real-time
Solution Approach 1:
The support projections are designed to be movable relative to the support surface, allowing them to dynamically adjust to the weight of vessels and substances. This dynamic capability enables precise weight detection through the weighing device while maintaining a relatively simple overall structure, as the movability is achieved through straightforward mechanical design rather than complex systems.

AI summary
A laboratory stand (1) comprises a base support (3) and support projections (4) which can themselves be set-up feet or else are provided in addition to such set-up feet. Furthermore, the laboratory stand (1) comprises a holding rod (2) for receiving instruments or measuring devices (12) for treating or examining media or substances or mixtures which may be contained or filled into a vessel (10) arranged next to the holding rod (2) in the usage position, into which vessel appropriate instruments or measuring instruments can engage from above. In order to be able to perform the metering of the substances in the vessel (10) prior to, or during, the processing in a simple manner and/or in order to be able to quickly and reliably identify weight changes, support projections (4) are movably mounted and provided with, or connected or provided with an operative connection to, a weighing apparatus such that the displacement of the set-up feet (4), which is increased in the case of increasing weight or reduced in the case of decreasing weight, can be determined as weight change.
