Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If windows are installed early in the construction process, then construction time is reduced, but windows are damaged or covered in dirt during structural work

Engineering Contradiction:
Improveconstruction timeVSAvoidwindow damage and dirt accumulation
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The formwork system is divided into modular wall panels with integrated window cavity formations, allowing the formwork to be segmented into functional zones. This enables windows to be installed in protected cavities during the formwork assembly phase, separating the window installation from the structural construction timeline and preventing damage while maintaining construction efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The window cavities are formed and prepared within the formwork structure before the actual window installation. The formwork panels are pre-configured with recesses and coupling formations that accommodate windows, allowing windows to be installed early in the construction sequence while protected from damage by the surrounding formwork structure.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If windows are installed at the end of construction, then windows are protected from damage, but construction time is extended

Engineering Contradiction:
Improvewindow protection from damageVSAvoidconstruction time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The formwork system is pre-configured with integrated window cavity formations and coupling mechanisms during the formwork assembly phase. This preliminary preparation allows windows to be installed early in the construction sequence while protected by the surrounding formwork structure, eliminating the need to extend construction time for late-stage window installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The window cavity formations are merged with the formwork panel structure, integrating window installation capabilities directly into the formwork system. This combination allows windows to be installed concurrently with formwork assembly, protecting them from damage while maintaining efficient construction timing.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If modular plastic formwork units are used, then ease of assembly is improved, but structural stability and insulation performance are insufficient

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The formwork system combines modular plastic panels with integrated metal bracing elements and spacer connectors to create a composite structure. The plastic panels provide ease of assembly while the metal bracing and spacers reinforce structural stability and create insulation spaces, achieving both ease of operation and structural integrity.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The formwork system is segmented into modular panels with integrated coupling formations that connect to bracing elements. This segmentation allows for easy assembly of individual panels while the interconnected bracing system provides overall structural stability, resolving the contradiction between ease of assembly and structural integrity.

Inventive Principle:
Principle #1Segmentation

4Stability of the object's composition

If wall panels are spaced apart to form insulation space, then insulation performance is improved, but device complexity increases due to additional connectors

Engineering Contradiction:
Improveinsulation performanceVSAvoidconnector complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The spacer connectors are merged with the bracing elements, combining the functions of structural support and insulation space creation into a single integrated component. This reduces the number of separate parts and simplifies the assembly process while maintaining the insulation performance provided by the spaced-apart wall panels.

Inventive Principle:
Principle #5Merging (Combining)
