Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed design with plain printed paper is used, then the structure is simple and easy to manufacture, but the display options are limited and lack tactile experience

Engineering Contradiction:
Improvedisplay optionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage case is divided into modular components: a base part, side elements, a holding frame, and interchangeable display elements. This segmentation allows different display elements to be swapped while maintaining the same structural framework, thus increasing display versatility without proportionally increasing overall structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display element is nested within the holding frame, which is in turn connected to the side elements of the storage case. This nested structure allows the display element to be integrated into the existing case structure, providing enhanced display options while utilizing the space and structural framework already present.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If interchangeable display elements are implemented, then flexibility in production and material usage increases, but the number of components and locking mechanisms increases

Engineering Contradiction:
Improveflexibility in productionVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holding frame with its taps and grooves serves as a universal interface that can accommodate different types of display elements through standardized mechanical locking. This universal connection mechanism allows the same structural component to work with multiple different display elements, providing production flexibility without requiring a unique structure for each display type.

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

3Reliability

If a holding frame with mechanical locking mechanisms is used, then secure connection of display elements is achieved, but the assembly process becomes more complex

Engineering Contradiction:
Improveconnection securityVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The mechanical locking mechanism with taps and grooves is designed to automatically engage and secure the display element to the holding frame through deformation and interlocking. This self-securing mechanism reduces the need for additional fastening steps or complex assembly procedures, maintaining ease of manufacture while ensuring reliable connection.

Inventive Principle:
Principle #25Self-service
