Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional anchoring methods with drilling and fastening means are used, then stable floor joist construction is achieved, but installation time increases significantly

Engineering Contradiction:
Improvestable floor joist constructionVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention extracts the anchoring function from the traditional drilling and fastening process by using a foot element with a lower base part that can be directly fixed to the support surface without drilling. This eliminates the time-consuming drilling operation while maintaining stable anchoring through the base part's contact with the support surface and optional adhesive or mechanical fixation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The foot element acts as an intermediary component between the floor joist and the support surface. It provides a simplified anchoring interface that eliminates the need for direct drilling into the support surface, thereby reducing installation time while maintaining structural stability through its base part's contact with the support surface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If traditional floor constructions without dampening layers are used, then simpler structure is achieved, but vibration and noise increase

Engineering Contradiction:
Improvestructure simplicityVSAvoidvibration and noise
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The dampening layer is incorporated into the foot element as a preliminary measure to counteract vibrations and noise before they can propagate through the floor construction. This preliminary anti-action against harmful vibrations is integrated into the basic structure, providing vibration absorption without requiring additional separate dampening components.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The foot element is constructed as a composite structure combining a lower base part, dampening layer, and upper connection part. The dampening layer is made of vibration-absorbing material that reduces noise and vibration transmission, while the base part provides structural support and anchoring functionality, creating a multi-functional composite component.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If complex bar systems with enclosing bars and level adjustment mechanisms are used, then functional requirements are met, but construction becomes heavy and expensive

Engineering Contradiction:
Improvefunctional requirementsVSAvoidconstruction weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The invention segments the support function into distinct components: the foot element with lower base part for anchoring, dampening layer for vibration absorption, and upper connection part for level adjustment. This segmentation allows each component to be optimized independently, reducing overall weight while maintaining all necessary functions compared to monolithic bar systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using heavy enclosing bars to provide structural support, the invention uses a simplified foot element design that copies the essential support function through its lower base part's contact with the support surface. This eliminates the need for heavy enclosing structures while maintaining structural integrity and functionality.

Inventive Principle:
Principle #26Copying

4Reliability

If drilling and anchoring operations are performed, then secure attachment to support surface is achieved, but construction cost increases

Engineering Contradiction:
Improvesecure attachmentVSAvoidconstruction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts the costly drilling and anchoring operations by using a foot element with lower base part that attaches to the support surface through simpler means such as adhesive or mechanical fixation without drilling. This eliminates expensive drilling equipment and materials while maintaining secure attachment through the base part's contact with the support surface.

Inventive Principle:
Principle #2Taking out (Extraction)
