Innovation Solution

A metal frame body with a deformable receiving groove leg, allowing for greater strength and flexibility, enabling the production of large windows and doors in various colors and configurations, with a deformable L-shaped leg design that compensates for size variations and tolerances, and includes a spacer for secure installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the frame body is made of plastic with a rigid receiving groove design, then the manufacturing precision can be maintained, but the adaptability and flexibility for large-area windows and doors are limited

Engineering Contradiction:

Improveadaptability for large-area windows and doorsVSAvoidfitting precision of receiving groove

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The receiving groove is designed with a deformable leg that can flexibly adjust during installation. The leg includes a deformation zone with reduced wall thickness that allows controlled bending, enabling the groove to adapt to dimensional variations and tolerances in large window and door frames while maintaining secure engagement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The wall thickness of the leg in the deformation zone is reduced to create a flexible region. This parameter change allows the leg to bend and deform under load, providing adaptability for accommodating size variations and inclinations in large-area window and door installations.

Inventive Principle:

Principle #35Parameter changes

2Strength

If the frame body is made of metal for high strength, then large window and door surfaces can be supported, but the manufacturing complexity and color customization become more difficult

Engineering Contradiction:

Improvestrength for large window and door surfacesVSAvoidcolor customization and manufacturing flexibility

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The metal profile body is equipped with a coating layer that can be applied in various colors to match customer requirements. This allows metal frames to achieve the color customization capability traditionally associated with plastic frames, while retaining the structural advantages of metal.

Inventive Principle:

Principle #32Color changes

3Manufacturing precision

If the receiving groove has a rigid design for precise fit, then the assembly precision can be ensured, but the flexibility to compensate for size variations and inclinations is reduced

Engineering Contradiction:

Improveassembly precision of frameVSAvoidflexibility to compensate for size variations

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The receiving groove incorporates a deformable leg with a deformation zone that allows controlled bending. This dynamic design enables the groove to adapt to dimensional variations and frame inclinations during installation while maintaining secure engagement with the frame.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The deformable leg is designed to absorb and compensate for tolerance variations and size discrepancies before final assembly. The flexible region acts as a cushion that accommodates imperfections in advance, ensuring smooth installation without requiring extremely tight tolerances.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Ease of operation

If the leg of the receiving groove rests directly on the wall opening end face, then the installation is simple, but the flexibility and adaptability are limited

Engineering Contradiction:

Improveinstallation simplicityVSAvoidflexibility and adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The leg is designed with a deformation zone that allows it to bend and adapt during installation. This dynamic design maintains the simplicity of direct placement on the wall opening end face while adding the flexibility to accommodate various installation conditions and dimensional variations.

Inventive Principle:

Principle #15Dynamics
