Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the air sealing device uses a fixed ferromagnetic plate positioned relative to the front wall, then the magnetic adhesion with the closure element is achieved, but the installation becomes complex and requires precise calibration of the plate position and inclination

Engineering Contradiction:
Improvemagnetic adhesion effectivenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ferromagnetic plate is made adjustable in position and inclination through fastening means that allow modification of the plate's orientation. This dynamic adjustability enables the plate to be optimally positioned relative to the closure element during installation, eliminating the need for complex pre-calibration of fixed positions and inclinations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The plate's position parameters (vertical and horizontal positioning) and inclination angle are made variable through the adjustable fastening system. This allows the parameters to be changed during installation to achieve optimal magnetic adhesion, transforming a complex fixed-configuration problem into a simple adjustment process.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the ferromagnetic plate position is precisely calibrated for optimal magnetic adhesion, then the sealing effectiveness is improved, but the assembly time increases due to the calibration process

Engineering Contradiction:
Improvesealing effectivenessVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The adjustable fastening system is pre-configured with multiple positioning options and adjustment mechanisms during manufacturing. This preliminary preparation of the adjustment capability eliminates the need for time-consuming on-site calibration, as installers can quickly adjust the plate to the optimal position using the pre-provided fastening means.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adjustment mechanism is designed to be self-adjusting, allowing installers to easily modify the plate position and inclination without requiring complex calibration procedures or specialized tools. The fastening means enable the plate to be repositioned and reclined simply by manipulating the adjustment components.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If the air sealing device is designed with fixed geometric parameters for the plate and wing, then the manufacturing is simplified, but the adaptability to different closure element positions is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidposition adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The air sealing device is divided into separate functional components: the ferromagnetic plate, the base structure, and the adjustable fastening means. This segmentation allows the plate to be manufactured with simple fixed geometry while the fastening system provides the adaptability to adjust the plate's final position and inclination to match different closure element configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening system transforms the static fixed-geometry design into a dynamic adjustable configuration. The plate maintains simple fixed manufacturing parameters, but the fastening means enable dynamic repositioning and reclining of the plate to adapt to various closure element positions and orientations.

Inventive Principle:
Principle #15Dynamics

Function Achieved in This Case

The solution enables fast and definitive installation of the sealing device, reducing assembly time and costs while ensuring effective air sealing, allowing for efficient adjustment of the sealing members to match the position of the closure element in its lowered configuration.

Implementation Method 1

The portions 33, 34 and 36 may form part of an integral member 32 obtained as a result of bending a single sheet of ferromagnetic material. The shape of the member 32 and the arrangements of the portion 36 and of the member 40 must be precisely calibrated so that the portion 36 and the member 40 assume a mutually facing and close position in the lowered configuration of the closure element 20, such as to allow their mutual adhesion by magnetic attraction in order to close the space 30 and block the passage of air through it.

AI summary

A liftable closure comprises a closure element (20) movable between a lowered and a raised configuration, associated with a portal structure (12) above which there is a compartment (26) for storing the closure element (20) delimited by a front wall (28), a space (30) being provided which communicates with the compartment (26) and with the outer environment between said wall (28) and the closure element (20). An air seal device for the liftable closure includes first and second sealing members (32a, 40; 32b, 40) adapted to reach a facing position in which they adhere by magnetic attraction to close the transverse space (30), one connected to said wall (28) for the support of a ferromagnetic plate (36a; 36b), the other consisting of a magnetic member (40) fixed to the closure element (20). The first sealing member (32a; 32b) comprises a base structure (42) which can be fixed to said wall (28) by means of first and second adjustable fixing means (44, 48) of the plate (36a; 36b) on said wall (28) in a position exactly corresponding to the position of the sealing member fixed to the surface of the closure element (20).
