An insulated door leaf for a gate, a gate comprising an insulated door leaf, and use of an insulating baffle in a door leaf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulated gates between cold and hot storage rooms face challenges in maintaining efficiency due to the trade-off between insulation and operation speed, with existing solutions either reducing speed or requiring complex mechanisms, and existing door leaves are not adaptable for different types of gates or easily repairable.
Innovation Solution
An insulated door leaf design featuring insulating baffles with through-going channels and cords that allow for high-speed movement and easy repair, enabling use in various gate types by allowing the door leaf to bend and be stacked during transportation, and incorporating a biasing cassette for improved insulation and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the amount of insulating material is increased to improve insulation efficiency, then the opening and closing speed of the door decreases
Solution Approach 1:
The door leaf is divided into multiple separate insulating baffles (first baffle, second baffle, third baffle, etc.) that can move independently through the roller. Each baffle is a separate unit that contributes to the overall insulation while allowing the door to maintain flexibility and speed during operation.
Solution Approach 2:
The insulating baffles are designed to be dynamic rather than static - they can move independently as the door opens and closes, and can be stacked during transportation. This dynamic configuration allows the door to achieve both high insulation efficiency when closed and high operating speed during movement.
2Loss of energy
If the amount of insulating material is increased to improve insulation efficiency, then the gate operating mechanism becomes more complex and heavier
Solution Approach 1:
By segmenting the insulation into multiple independent baffles, the system avoids the need for a single complex insulated structure. Each baffle is a simple unit that can be independently managed, reducing the overall complexity of the operating mechanism while maintaining high insulation efficiency.
Solution Approach 2:
The baffles are designed to be replaceable individual units. If one baffle becomes damaged or worn, only that specific baffle needs to be replaced rather than the entire door leaf or insulation system, simplifying maintenance and reducing operational costs.
3Adaptability or versatility
If the door leaf is designed with inclined edges for roller gate compatibility, then the door leaf thickness decreases causing a drop in insulation efficiency
Solution Approach 1:
The door leaf is segmented into multiple baffles of uniform thickness rather than a single piece with varying thickness. This segmentation allows each baffle to maintain consistent insulation properties while the overall door structure adapts to roller gate requirements through the flexible arrangement of multiple units.
Solution Approach 2:
Instead of changing the thickness parameter of the door leaf (which would reduce insulation), the invention changes the configurational parameters - the number, arrangement, and movement characteristics of multiple baffles. This allows the door to adapt to different gate types while maintaining constant baffle thickness and insulation efficiency.
4Reliability
If the door leaf is designed as a single unit, then replacement is required if damaged, increasing operation costs
Solution Approach 1:
The door leaf is segmented into multiple independent baffle units that can be individually replaced. This segmentation transforms the repair strategy from replacing an entire door leaf to replacing only the damaged baffle, significantly reducing operation costs and maintenance complexity.
Solution Approach 2:
The design enables selective replacement of damaged baffles while retaining functional ones. This approach recovers the value of undamaged components and reduces waste, allowing the door system to maintain reliability with minimal intervention and cost.
