Solution Overview

Problem

Conventional modular sofas lack the ability to independently select and position seaters, backs, and armrests, and integrate rigid support surfaces, limiting customization and flexibility while being costly and complex to manufacture.

Innovation Solution

A modular sofa design featuring tracks with hooking means and connecting elements that allow for the removable and adjustable attachment of seaters, backs, armrests, and rigid support surfaces, enabling infinite configuration options with standardized components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional modular sofa designs are used, then manufacturing is simpler with predefined solutions, but customization options are limited and flexibility is reduced

Engineering Contradiction:
Improvecustomization optionsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sofa is divided into independent modular components (seaters, backs, armrests, support surfaces) that can be selectively assembled. Each module features standardized connection interfaces (tracks with hooking means) that enable flexible reconfiguration without requiring complex custom manufacturing for each configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The track system with hooking means serves as a universal connection interface that can accommodate multiple types of components (seaters, backs, armrests, rigid support surfaces). This single standardized mechanism provides multi-functional attachment capability, reducing the need for different connection systems for different components.

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

2Adaptability or versatility

If predefined sofa compositions are used, then manufacturing costs are lower, but the ability to independently select and position components is limited

Engineering Contradiction:
Improveindependent component selectionVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the sofa into independently selectable modules with standardized connections, the system allows customers to choose only the components they need, reducing inventory requirements and manufacturing complexity while maintaining cost-effectiveness through standardized production of individual modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized track and hooking means system establishes fixed geometric parameters and connection protocols that enable automated or semi-automated assembly processes. This standardization maintains manufacturing efficiency while enabling unlimited configuration variations through different component combinations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If fixed sofa configurations are used, then structural stability is maintained, but positioning flexibility of cushions and armrests is reduced

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The connection system transitions from fixed rigid attachments to a dynamic modular system where components can be positioned at various locations along the tracks and securely locked. The hooking means provide stable fixation at selected positions while allowing repositioning when needed, combining structural stability with positioning flexibility.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If integrated rigid support surfaces are added to modular sofas, then functional versatility is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:
Improvefunctional integrationVSAvoidintegration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The track system with hooking means serves as a universal mounting interface that can accommodate both soft components (cushions, armrests) and rigid support surfaces (commodes, tables). This single standardized mechanism provides multi-functional attachment capability, reducing the need for different connection systems for different component types.

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