Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional monobloc formwork is manufactured for each specific opening dimension, then the formwork can be precisely fitted to the required opening size, but the formwork becomes single-use waste that must be removed and processed, generating significant transportation and disposal issues

Engineering Contradiction:
Improveformwork dimension precisionVSAvoidformwork waste
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The formwork device is divided into multiple detachable panels (main panels and additional panels) that can be separated and reused. Each panel is a discrete component that can be independently recovered and reassigned to different formwork assemblies, eliminating the need to discard entire monobloc formworks after a single use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The formwork system transitions from a static monobloc structure to a dynamic, reconfigurable assembly. Panels can be detached, repositioned, and reassembled in different configurations to match various opening dimensions, allowing the same physical components to adapt to multiple applications throughout the construction project and beyond.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If custom monobloc formwork is manufactured for each opening, then the formwork matches the specific opening dimensions, but as many specific formworks must be manufactured as there are openings of varying sizes, increasing manufacturing complexity and waste

Engineering Contradiction:
Improveformwork adaptability to opening dimensionsVSAvoidformwork manufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A universal set of standardized panels serves multiple functions across different opening configurations. The same main panels and additional panels can be combined in various arrangements to create formwork for openings of different sizes and shapes, eliminating the need to manufacture custom monobloc formworks for each specific opening while maintaining precise dimensional adaptation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If traditional formwork is used for openings of varying sizes, then each opening requires a specific formwork, but this generates a significant number of road transports as construction progresses and building plans are distributed

Engineering Contradiction:
Improveopening dimension accuracyVSAvoidtransportation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

By segmenting the formwork into standardized panels, the system enables rapid reconfiguration on-site without requiring transportation of complete custom formworks for each opening. Panels can be locally assembled and disassembled, significantly reducing the need for road transports as construction progresses and plans are distributed.

Inventive Principle:
Principle #1Segmentation

4Strength

If monobloc formwork is used, then the formwork structure is simple and robust, but the formwork becomes bulky waste that must be removed and processed after use

Engineering Contradiction:
Improveformwork structural integrityVSAvoidformwork waste volume
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The formwork is segmented into multiple panels connected by joining means, allowing the structure to maintain robustness during use while enabling complete disassembly after use. Each panel can be independently recovered and reused, transforming what would be bulky waste from monobloc formwork into reusable components that circulate through multiple construction projects.

Inventive Principle:
Principle #1Segmentation
