Specific Gravity Measurement via Segmented Liquid Bath Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specific gravity measuring apparatuses experience accuracy issues due to the need to open and close the aerial mounting member, which causes physical shocks and subtle variations in measured values.
Innovation Solution
The apparatus is designed such that the aerial mounting member covers only a part of the liquid bath's opening, allowing the measured object to be dropped directly onto the receiving member without opening and closing, eliminating the need for labor-intensive operations and reducing physical shocks, with a simplified support structure and a concave dish-shaped mounting portion to prevent accidental rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aerial mounting member is fully opened and closed to measure weight in air and weight in water, then the measurement process can be completed, but physical shock is given to the weighing apparatus causing measurement accuracy to deteriorate
Solution Approach 1:
The opening of the liquid bath is segmented into two zones: a first opening for receiving the aerial mounting member and a second opening for receiving the measured object receiving member. This segmentation allows the aerial mounting member to remain in place while enabling object transfer, eliminating the need to open and close the aerial mounting member repeatedly.
Solution Approach 2:
A partition wall is introduced as an intermediary structure that divides the liquid bath opening into two separate openings. This partition wall enables independent access to different functional zones (aerial mounting and object receiving) without requiring the aerial mounting member to be opened or closed, thus preventing physical shock to the weighing apparatus.
2Productivity
If the aerial mounting member is opened and closed repeatedly, then the measurement steps can be completed, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The opening is segmented into a first opening and a second opening, allowing simultaneous or sequential access to the aerial mounting member and the measured object receiving member. This eliminates the need for repeated opening and closing operations, simplifying the操作流程 and improving measurement efficiency.
Solution Approach 2:
The partition wall is pre-configured to create separate access openings before measurement begins. This preliminary structural arrangement enables direct placement of objects without requiring intermediate opening and closing actions during the measurement process, reducing operational complexity and time.

AI summary
A specific gravity measuring apparatus includes a liquid bath, a measured object receiving member which is housed in the liquid bath via a support means in a non-contact manner and into and out of which a liquid within the liquid bath can freely flow, an aerial mounting member which is supported by the support means and on which a measured object is placed in order to measure gravity thereof in the air, and a weighing apparatus receiving and supporting the measured object receiving member via the support means. The weighing apparatus 5 is provided with a sensor and a measuring section. The aerial mounting member is provided in such a manner as to cover a part of an opening O at an upper part of the liquid bath.
