Innovation Solution

A building design featuring a completely enclosed shell that eliminates the need for traditional openings for natural lighting, ventilation, and fire escape, while providing alternative solutions for these requirements, allowing for flexible and adaptable living spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional building construction methods are used to achieve high-density urban development, then land utilization efficiency is improved, but quality of life deteriorates due to lack of privacy, natural light, and adaptable living spaces

Engineering Contradiction:
Improveland utilization efficiencyVSAvoidadaptability to different life stages
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The building shell is designed as a dynamic, transformable structure that can be reconfigured from enclosed to open states. This allows the same physical space to adapt to different life stages and family compositions, resolving the contradiction between high-density fixed construction and the need for adaptability to changing life circumstances

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The building is divided into modular units with standardized interfaces, allowing flexible reconfiguration of internal and external spaces. This segmentation enables the structure to be adapted for different densities and living arrangements while maintaining construction efficiency

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If traditional building construction with openings for natural lighting and ventilation is used, then quality of life is improved, but building density and land utilization deteriorate

Engineering Contradiction:
Improvequality of lifeVSAvoidbuilding density
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The shell structure can dynamically open and close to provide natural light and ventilation when needed, then close to enable higher density configurations. This dynamic behavior allows the building to achieve both high quality of life and high building density at different times

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The transformable shell serves multiple functions: it provides structural enclosure, enables natural lighting when opened, allows ventilation, and facilitates fire escape. This multi-functionality eliminates the need for separate dedicated openings, thereby increasing building density while maintaining quality of life

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

3Productivity

If enclosed building shells without openings are used to achieve high density, then building density is improved, but natural lighting, ventilation, and fire safety deteriorate

Engineering Contradiction:
Improvebuilding densityVSAvoidnatural light
Core Design Contradiction:
ProductivityVSIllumination intensity

Solution Approach 1:

The shell sections can be dynamically opened to allow natural light penetration and ventilation, then closed to achieve dense urban configurations. This temporal separation of functions allows the building to provide natural light when needed while maintaining high density overall

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The building utilizes vertical stacking and multi-level configurations where shell sections can be opened at different heights and positions. This three-dimensional approach to opening/closing allows natural light and ventilation to penetrate deep into the building while maintaining high ground-level density

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of manufacture

If fixed living spaces are provided to simplify construction, then construction complexity is reduced, but flexibility for changing life circumstances deteriorates

Engineering Contradiction:
Improveconstruction simplicityVSAvoidflexibility for life changes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The building is constructed from standardized modular units with uniform connection details, simplifying construction while enabling flexible reconfiguration. The modular segmentation allows simple manufacturing processes while providing adaptability through different module arrangements

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transformable shell and reconfigurable interior partitions provide dynamic adaptability without requiring complex custom construction. The standardized dynamic mechanisms can be replicated across modules, maintaining construction simplicity while enabling flexibility for life changes

Inventive Principle:
Principle #15Dynamics
