Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If prefabricated building elements with large glass areas and outer doors are used to create recreational areas, then the standard of living is improved, but thermal comfort and energy efficiency are reduced

Engineering Contradiction:

Improvestandard of livingVSAvoidenergy efficiency

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The energy accumulator is nested within the structural foundation of the building element, specifically within the frame between upper and lower sheet shaped elements. This integration allows the energy storage system to be concealed within the existing structure without adding external bulk, resolving the contradiction by embedding functionality within the architectural form.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The building element serves multiple functions: it provides the structural foundation for the recreational area while simultaneously housing an energy accumulator that stores and supplies energy to the building. This multi-functionality addresses both the need for recreational space and energy efficiency improvement within a single integrated system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of energy

If an energy accumulator is integrated into the building element, then energy efficiency is improved, but the structural complexity increases

Engineering Contradiction:

Improveenergy efficiencyVSAvoidstructural complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The energy accumulator is merged with the structural foundation components (frame, upper sheet shaped element, lower sheet shaped element) into a single integrated building element. This combination eliminates the need for separate energy storage infrastructure, reducing overall system complexity while maintaining energy efficiency benefits.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The energy accumulator is nested within the compartment formed by the frame and sheet shaped elements, utilizing the existing structural space for dual purposes. This nesting approach adds energy storage functionality without requiring additional external structural complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If the energy accumulator is positioned outside the building, then fire risk is reduced, but protection from external damage is compromised

Engineering Contradiction:

Improvefire riskVSAvoidprotection from external damage

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The energy accumulator is nested within the protected compartment of the building element's structural foundation, shielded by the frame and sheet shaped elements from external environmental damage, while its integration into the balcony structure maintains safe separation from the main building interior, thus reducing fire risk propagation.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The structural foundation components (frame, upper and lower sheet shaped elements) act as intermediary protective barriers between the energy accumulator and external environmental factors, providing protection from damage while maintaining the safety separation that reduces fire risk to the main building.

Inventive Principle:

Principle #24Intermediary (Mediator)
