Solution Overview

Problem

Existing interior wall construction systems are inflexible and costly, failing to adapt to changing domestic space needs, such as varying dimensions and privacy requirements, and often result in waste and ecological footprint due to demolition and reconstruction.

Innovation Solution

A modular interior wall system using 'U' shaped rails fixed to floors, walls, and ceilings, allowing for easy assembly and disassembly without damaging components, using reusable materials like wood and composites, and incorporating thermal and acoustic insulation panels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional masonry or gypsum plasterboard walls are used, then structural strength and stability are achieved, but adaptability to changing space needs deteriorates and demolition waste increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability to space reconfiguration

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The wall system is divided into modular components including vertical profiles, horizontal rails, and interchangeable panels that can be independently assembled and disassembled. This segmentation enables flexible reconfiguration while maintaining structural integrity through standardized connection mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from static conventional walls to a dynamic modular structure where components can be easily repositioned, added, or removed. The profiles and panels are designed with movable connections that allow adaptation to changing spatial requirements without compromising structural stability.

Inventive Principle:

Principle #15Dynamics

2Productivity

If fixed conventional construction systems are used, then initial construction speed is achieved, but future renovation flexibility deteriorates and costs increase

Engineering Contradiction:

Improveinitial construction speedVSAvoidrenovation flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The modular components are pre-fabricated with standardized connection features and dimensions during manufacturing. This preliminary preparation enables rapid assembly during initial construction and equally rapid reconfiguration during renovations, eliminating the need for time-consuming on-site modifications.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The profiles and connection elements are designed as universal components that serve multiple functions: structural support, panel attachment, and easy disconnection. This multi-functionality allows the same components to be used in both initial construction and future renovations, maintaining productivity while enabling flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If modular office partition systems are used, then quick assembly is achieved, but acoustic and thermal isolation deteriorates and aesthetic quality for domestic spaces worsens

Engineering Contradiction:

Improveassembly easeVSAvoidacoustic and thermal isolation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system employs composite panel constructions combining insulating materials (foam, mineral wool) with decorative facing materials (wood veneers, laminates). This composite structure provides effective acoustic and thermal isolation while maintaining aesthetic quality suitable for domestic environments, all within the easy-to-assemble modular framework.

Inventive Principle:

Principle #40Composite materials

4Adaptability or versatility

If demolition and reconstruction is performed, then space reconfiguration is achieved, but material waste increases and ecological footprint deteriorates

Engineering Contradiction:

Improvespace reconfiguration capabilityVSAvoidmaterial waste

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The modular system is designed for complete disassembly and component recovery. When reconfiguration is needed, individual panels, profiles, and connectors can be removed and reused in new configurations, dramatically reducing material waste and ecological footprint compared to traditional demolition approaches.

Inventive Principle:

Principle #34Discarding and recovering
