Solution Overview

Problem

Conventional sofas are designed as one-piece units, making them large, cumbersome, and costly to transport and customize, with high material costs and limited flexibility in size and configuration.

Innovation Solution

A modular sectional sofa design featuring a separable bottom frame and backrest frame connected via hook bodies and U-shaped connection elements, allowing for adjustable configurations and easy assembly/disassembly, with a cushion that can be detached for cleaning and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a one-piece sofa design is used, then structural stability is improved, but the size and weight increase making transportation inconvenient

Engineering Contradiction:
Improvestructural stabilityVSAvoidsofa weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The sofa is divided into multiple independent modules including seat modules, backrest modules, and armrest modules that can be separated and reconfigured. Each module has standardized connection interfaces (hole slots and connecting pieces) that enable easy assembly and disassembly while maintaining structural stability when connected, thus reducing transportation weight and complexity without sacrificing overall structural integrity.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a one-piece sofa design is used, then structural stability is improved, but handling convenience deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidhandling convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The sofa structure is segmented into movable modules with standardized connection mechanisms. The connecting pieces with inserting parts and matching hole slots allow modules to be easily detached and reattached, enabling simple handling, moving, and reconfiguration while maintaining stable connections during use.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple sofa products are designed to meet different requirements, then adaptability is improved, but manufacturing complexity and costs increase

Engineering Contradiction:
Improvesofa configuration varietyVSAvoidproduct management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sofa system uses universal standardized modules (seat modules, backrest modules, armrest modules) with consistent connection interfaces that can be combined in multiple configurations. This modular approach allows a single set of components to create various sofa types and sizes, providing high adaptability while simplifying manufacturing and inventory management compared to producing entirely different sofa models.

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

4Adaptability or versatility

If multiple sofa products are designed to meet different requirements, then adaptability is improved, but material costs increase

Engineering Contradiction:
Improvesofa configuration varietyVSAvoidraw material costs
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The design employs universal modules that can serve multiple functions and configurations. The same seat modules, backrest modules, and connecting pieces can be reused across different sofa arrangements, reducing the total quantity of raw materials needed compared to manufacturing separate dedicated sofa products for each configuration requirement.

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