Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flexible materials are used to construct the apparatus, then the apparatus can be bent and adapted to different configurations, but the apparatus lacks structural stability and rigidity when needed

Engineering Contradiction:
ImproveflexibilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The apparatus employs adjustable members that can dynamically change their state between engaged and disengaged configurations. When engaged, these members provide structural support and rigidity; when disengaged, they allow the flexible layer to bend and conform. This dynamic adjustment capability enables the apparatus to transition between stable and flexible states as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The apparatus changes its structural parameters by moving adjustable members between different positions and configurations. By altering the engagement state of these members, the apparatus modifies its effective stiffness and structural integrity, transforming from a rigid-supported state to a flexible state without changing the physical composition of the flexible layer itself.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If adjustable members are added to enable switching between flexible and rigid configurations, then the apparatus gains versatility, but the device complexity increases

Engineering Contradiction:
Improveconfiguration switching capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The apparatus utilizes a flexible layer as its primary structural component, eliminating the need for rigid frames or complex mechanical assemblies. The adjustable members interact with this flexible layer to provide support when needed, maintaining overall simplicity while enabling configuration changes.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent replaces complex mechanical locking or rigid connection systems with simpler adjustable members that can be positioned to provide support or allow flexibility. This substitution reduces the number of moving parts and mechanical interfaces required to achieve the same functional outcome.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
