Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional building elements are used, then the structure is simple and easy to manufacture, but the user engagement and assembly verification are insufficient

Engineering Contradiction:
Improveassembly verificationVSAvoidbuilding element structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies hydrochromic layers that change color when exposed to water, allowing the building elements to visually indicate assembly status. When two elements are properly connected, the hydrochromic layers at the interface change color to provide visual feedback that assembly is correct, thereby improving assembly verification without significantly complicating the overall structure.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The hydrochromic color change mechanism provides immediate visual feedback to the user about assembly correctness. This feedback system allows users to verify proper connection of building elements through color changes at the interface, enhancing reliability of assembly verification while maintaining relatively simple element structures.

Inventive Principle:
Principle #23Feedback

2Reliability

If hydrochromic layers are added to building elements, then assembly verification is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveassembly verificationVSAvoidbuilding element production
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The hydrochromic layers are applied as coatings on the building element surfaces, particularly at connection interfaces. These layers change color upon water exposure to indicate proper assembly, providing reliable verification while using a manufacturing process that involves coating existing simple geometric shapes, thus limiting the increase in manufacturing complexity.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The building elements combine conventional plastic or material structures with hydrochromic coating layers, creating composite structures that leverage the simplicity of traditional building blocks while adding the verification functionality of hydrochromic materials. This composite approach allows manufacturing to proceed in stages, first forming the basic element shapes then applying the functional coating.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If static configurations are used, then manufacturing is simple, but user engagement and interactivity are reduced

Engineering Contradiction:
Improveuser engagementVSAvoidbuilding element structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces dynamic color-changing properties to otherwise static building elements. The hydrochromic layers remain inactive until water is applied during assembly, at which point they dynamically change color to provide visual feedback. This adds interactivity and user engagement while maintaining the static geometric simplicity of the building elements themselves.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hydrochromic color change mechanism transforms static building elements into dynamic, interactive components. When users assemble elements and water contacts the hydrochromic layers at connection points, the color changes provide immediate visual feedback, enhancing user engagement and making the assembly process more interactive without requiring complex mechanical or electronic systems.

Inventive Principle:
Principle #32Color changes
