Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrophoresis devices face difficulties in maintaining constant temperature within the thermostat and in easily attaching or detaching the capillary array unit due to the curved wind direction control plate, which limits the range of motion and causes temperature variations.
Innovation Solution
The electrophoresis device incorporates a capillary array unit with a support, a pump mechanism, a detection unit, and a thermostat with a heat source and fan, featuring a straightening plate to adjust air flow and facilitate capillary attachment/detachment, while reducing temperature variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a curved wind direction control plate is arranged along the capillary periphery to control air flow, then temperature uniformity is improved, but the range of motion of the capillary is limited making attachment/detachment difficult
Solution Approach 1:
The wind direction control plate is divided into a fixed portion attached to the thermostat housing and a movable portion that can move relative to the fixed portion. This segmentation allows the plate to control air flow when needed while being movable out of the way during capillary attachment/detachment operations.
Solution Approach 2:
The wind direction control plate transitions from a static curved structure to a dynamic system where the movable portion can change its position. The plate is designed to be movable between a first position (controlling air flow for temperature uniformity) and a second position (clearing the path for capillary attachment/detachment).
2Stability of the object's composition
If the wind direction control plate is fixed in position to maintain temperature control, then temperature stability is improved, but the capillary cannot be easily attached or detached
Solution Approach 1:
The wind direction control plate is designed with movable characteristics, allowing it to transition between different positions. The movable portion can be positioned to stabilize temperature during analysis, then moved to facilitate capillary attachment and detachment operations.
Solution Approach 2:
The movable portion of the wind direction control plate can be preliminarily positioned to clear the attachment path before capillary installation, and then moved to its temperature control position after attachment is complete. This preliminary action resolves the conflict between accessibility and temperature stability.
