Solution Overview
Problem
In cold storage facilities, a large temperature difference leads to significant dew condensation on sliding doors and frames, which can accumulate on lower frames without being completely drained, reducing efficiency.
Innovation Solution
A cold storage design featuring a sliding door with a vertically extending drain channel and a porous body with water permeability attached to the door's upper surface, establishing fluid communication with the drain channel to enhance drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a drain hole is formed in the lower frame to drain dew condensation water, then the drainage function is provided, but the dew condensation water may remain on the lower frame without being completely drained
Solution Approach 1:
The drainage system is segmented into multiple components: the drain hole in the lower frame, the drain channel in the sliding door, and the porous body. This segmentation allows water to be drained through multiple pathways simultaneously, improving overall drainage efficiency and preventing water accumulation on the lower frame.
Solution Approach 2:
The porous body acts as an intermediary component between the drain channel and the drain hole. It establishes fluid communication while controlling the flow of dew condensation water, enabling efficient drainage from the sliding door through the lower frame without causing water accumulation.
2Temperature
If the sliding door and frame are exposed to large temperature difference, then the cold storage function is maintained, but a relatively large amount of dew condensation water generates
Solution Approach 1:
The drainage system extracts the harmful dew condensation water that forms due to the temperature difference. The drain channel and porous body work together to remove the condensed water from the sliding door and frame surfaces, preventing water accumulation while maintaining the necessary temperature difference for cold storage function.
3Productivity
If a porous body with water permeability is attached to the sliding door to establish fluid communication with the drain channel, then the drainage efficiency is increased, but the device complexity increases
Solution Approach 1:
A porous body with water permeability is attached to the sliding door to establish fluid communication with the drain channel. The porous structure allows dew condensation water to pass through efficiently while adding minimal structural complexity. The porous material provides multiple flow pathways that enhance drainage efficiency without requiring complex mechanical components.
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
The solution effectively increases the efficiency of draining dew condensation water by suppressing the flow rate and ensuring that water is smoothly drained through the designated outlet, preventing accumulation on lower frames.
