Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample collection apparatuses disturb seabed sediment during sampling and fail to easily separate the sample collection box for transportation.
Innovation Solution
A sample collection apparatus with a frame section, vertical operation section, rotary operation section, and box-mounting unit that allows for stable seabed sediment collection and easy detachment of the sample collection box for transportation, using a trigger device and outflow prevention mechanism to prevent sample disturbance and loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sample box digs into the sediment to collect samples, then sample collection efficiency is improved, but the sediment is disturbed causing sample loss
Solution Approach 1:
The sample collection apparatus is divided into a frame section and a box-mounting unit that can be detached. The box-mounting unit with the sample box can be separated from the frame section after sampling, allowing the sample box to be transported independently to the laboratory without disturbing the collected sediment samples.
Solution Approach 2:
The sample box is extracted as a separate removable component from the collection apparatus. After the frame section completes the sampling operation by digging into the seabed, the box-mounting unit with the sealed sample box is detached and taken out for transportation, preventing any further disturbance to the samples.
2Stability of the object's composition
If the sample box is integrally configured in the collection apparatus, then structural stability is improved, but the sample box cannot be easily separated for transportation
Solution Approach 1:
The collection apparatus is segmented into a frame section and a box-mounting unit with distinct functions. The frame section provides structural stability during operation, while the box-mounting unit can be easily detached for transportation. This segmentation allows both structural stability and ease of separation to be achieved.
Solution Approach 2:
The connection between the frame section and box-mounting unit is designed to be dynamic - stable during the sampling operation but easily detachable afterward. The box-mounting unit can be separated from the frame section through simple operation, enabling flexible transition from a stable operational state to a transportable state.
3Ease of operation
If the box-mounting unit is designed for easy detachment, then transportation convenience is improved, but the reliability of sample containment may be compromised
Solution Approach 1:
The lower portion of the sample box is closed by the box opening/closing member before detachment occurs. This preliminary closing action ensures that samples are securely contained within the box before the box-mounting unit is separated from the frame section, preventing any sample loss during transportation while maintaining ease of detachment.
Solution Approach 2:
The box opening/closing member acts as an intermediary mechanism that ensures sample containment reliability. It automatically closes the lower opening of the sample box when the box-mounting unit is detached, serving as a mediator between the easy detachment function and the sample containment requirement.
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 stable seabed sediment collection without disturbing the seabed and facilitates easy transportation of the sample collection box using a moving carriage, ensuring minimal disturbance and efficient operation.
Implementation Method 1
the trigger device is operated, and the vertical operation member descends such that the sample collection box mounted on the box-mounting unit digs into the seabed surface
Implementation Method 2
the rotary members are rotated about the rotary shafts by pulling of the pulling cable such that the box opening/closing member closes the opened lower portion of the sample collection box
