Rotating Receiver Module for Density Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load receiver devices require separate configurations for determining the density of solid bodies that sink and float in a fluid, with additional components needed for floating bodies, leading to inefficiencies and unreliable holding in cases where densities are similar to the fluid.
Innovation Solution
A load receiver device with a pivotally mounted receiver module that can rotate 180° to adjust its concavity orientation between sinking and floating positions, eliminating the need for additional parts like buoyancy constraints, and incorporating a height-adjusting element to optimize immersion depth and locking mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate load receiver devices are used for sinking and floating bodies, then density determination of both types is possible, but device complexity increases
Solution Approach 1:
The load receiver device is designed with a rotatable receiver module that can be oriented in different positions to handle both sinking and floating bodies with a single device, eliminating the need for separate configurations and reducing overall device complexity
2Reliability
If a buoyancy constraint is added to hold floating bodies, then floating bodies can be held in place, but device complexity increases
Solution Approach 1:
Instead of adding a buoyancy constraint to push floating bodies down, the invention inverts the approach by orienting the concavity upward and using the body's own buoyancy force to push it into the concavity, thereby holding it in place without additional components
3Reliability
If the concavity orientation is fixed for sinking bodies, then sinking bodies are held reliably, but floating bodies cannot be held
Solution Approach 1:
The receiver module is made dynamically adjustable through rotation, allowing the concavity orientation to change from downward (for sinking bodies) to upward (for floating bodies), thereby maintaining reliable holding capability for both types of bodies
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable density determination of solid bodies with any density magnitude, including those similar to the fluid, by securely holding bodies in place without relying on gravity or buoyant forces, and eliminating the need for additional components, thus improving operational flexibility and accuracy.
Implementation Method 1
a solid body that sinks in the fluid can rest in the concavity because of the gravity force acting on the body
Implementation Method 2
a solid body that floats in the fluid can be held in place in the surrounding fluid by means of the concavity because of the buoyant force acting on the body

AI summary
A load receiver device that serves to receive at least one solid body and to hold the solid body in place in a surrounding fluid during a density determination. Embodiments of the load receiver device include a hanger module that is adapted to establish a hanging connection to a part that is, in turn, connected to the weighing cell of a balance. Embodiments of the load receiver device further include a receiver module that is connected to the hanger module and serves to receive a solid body. The receiver module has a concavity that is designed to receive the solid body, and the orientation of the concavity can be selectively reversed to maintain the position of the solid body in the surrounding fluid during a density determination, regardless of whether the solid body will otherwise sink or float in the fluid.
