Roller Gate Insulation via Segmented Pockets and Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick roller gates have low insulation ability, leading to them often being non-operational during the day due to limited insulation effect and slow roll-up/roll-down times, which results in energy inefficiencies in freezing houses with high truck traffic.
Innovation Solution
A roller gate with transverse pockets and inwardly inclined longitudinal block-shaped members, allowing for efficient insulation and quick operation, featuring a flexible artificial web with Neoprene or similar insulation material and a driving mechanism for rapid rolling, and incorporating vertical side guards with electrical heating elements to manage heat and prevent thermal bridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If existing quick roller gates are used, then the gate can be operated quickly during working hours, but the insulation ability is too low to be effective
Solution Approach 1:
The gate leaf is constructed as a composite structure with an outer flexible web layer and an inner insulation layer (such as foam or air gaps) formed by the pocket construction. This composite design allows the gate to maintain both quick operational speed and effective insulation capability, resolving the contradiction between speed and energy loss.
Solution Approach 2:
The pocket construction creates air-filled spaces within the gate leaf structure. These air pockets act as thermal insulators while maintaining the flexibility and quick-roll capability of the gate. The porous/air-filled structure provides insulation without compromising the rapid operation requirement.
2Loss of energy
If insulation material is added to improve insulation, then the insulation effect improves, but the roll-up time increases
Solution Approach 1:
The insulation is divided into discrete pocket sections rather than a solid continuous layer. This segmentation allows the insulation material to be compressed into a compact form during roll-up, reducing the time required, while still providing effective insulation when the gate is in the closed position.
Solution Approach 2:
The outer flexible web structure allows the insulation layers to be compressed and folded during the roll-up process. This flexibility enables the gate to maintain insulation capability while achieving rapid roll-up and roll-down times, as the flexible outer layer accommodates the insulation material's volume changes.
3Loss of energy
If thick insulation layers are used, then the insulation ability improves, but the gate complexity and maintenance requirements increase
Solution Approach 1:
The insulation is divided into discrete pocket sections rather than a solid continuous layer. This segmentation allows the insulation material to be compressed into a compact form during roll-up, reducing the time required, while still providing effective insulation when the gate is in the closed position.

AI summary
A roller gate (2) of the type which is typically used in gateways (4) in industrial buildings such as freezing houses or the like, where the gate or door leaf (6) by opening is rolled up around a reel system (8) operated by a driving mechanism (10), and where the gate or door leaf (6) consists of one or more layers of a flexible artificial web such as a reinforced tarpaulin web of PVC or polyester, where said one or more layers of said gate or door leaf (6) at a first side (12) of the gate or door leaf are factory-tailored with transverse directed pockets (14) and with a smooth surface at an opposite side (16) of the gate or door leaf (6) -as said first side (12) of the gate or door leaf (6) is facing inwards when rolled up around said reel system (8). By simple provisions may hereby be achieved very important improvements in the operation of the roller gate or door during daily use where a great number of trucks are passing in and out to and from a freezing house or room. In this connection it is very important that the claimed and described roller gate or door operates very quickly and with a minimum of maintenance work during the working day.
