Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional thermal insulation methods (capillary devices, glass fiber inserts) are used in profiled glass sheets, then thermal insulation properties are improved, but assembly complexity and production difficulty increase

Engineering Contradiction:

Improvethermal insulationVSAvoidassembly complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The thermal insulation is segmented into modular profiled glass sheets, each with integrated insulation cores. This allows standardized production and simplified assembly compared to traditional methods requiring complex fitting of capillary devices or glass fiber inserts between separate glass panes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The insulation material is merged with the glass profile structure itself, creating an integrated composite element. The heat-insulating core is positioned within the profiled glass sheet structure, combining the structural and insulation functions into a single assembly unit, eliminating the need for separate insulation installation steps.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of energy

If dimensionally stable translucent capillary devices or glass fiber inserts are fitted into profiled glass sheets, then thermal insulation is enhanced, but manufacturing precision requirements increase

Engineering Contradiction:

Improvethermal insulationVSAvoidassembly precision

Core Design Contradiction:

Loss of energyVSManufacturing precision

Solution Approach 1:

The heat-insulating core is pre-integrated into the profiled glass sheet structure during manufacturing. This preliminary integration ensures precise positioning and dimensional stability without requiring high-precision field assembly, as the insulation element is already correctly positioned within the profile structure before installation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The insulation material parameters are optimized for dimensional stability and thermal performance. The core uses materials with controlled thermal conductivity and dimensional properties that maintain insulation effectiveness while simplifying assembly tolerances compared to traditional capillary or glass fiber solutions.

Inventive Principle:

Principle #35Parameter changes

3Loss of energy

If multiple rows of profiled glass sheets are assembled to form double-shell or multi-shell arrangements, then thermal insulation capacity increases, but assembly time and complexity increase

Engineering Contradiction:

Improvethermal insulation capacityVSAvoidassembly time

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The multi-shell arrangement is segmented into standardized profiled glass sheet modules that can be independently manufactured and then quickly assembled. Each module contains integrated insulation, allowing parallel assembly of multiple shells without requiring complex coordination of separate insulation components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The profiled glass sheets are designed with universal connection features and standardized dimensions that allow the same components to be used across single-shell, double-shell, and multi-shell configurations. This universality simplifies the assembly process for multi-shell arrangements compared to traditional methods requiring different components for each shell layer.

Inventive Principle:

Principle #6Universality (Multi-functionality)
