Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional hinge device with multiple pieces and fixing screws is used, then the rotatable coupling function is achieved, but the system becomes expensive and difficult to install

Engineering Contradiction:
Improverotatable coupling functionVSAvoidinstallation difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the hinge device and mounting plate into a single integrated unit that performs both functions simultaneously. The mounting plate incorporates the hinge mechanism directly, eliminating the need for separate components and multiple fixing screws, thus simplifying installation while maintaining the rotatable coupling function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting plate is designed to serve multiple functions: it provides structural mounting support, incorporates the hinge mechanism for rotation, and includes adjustable components for positioning. This multi-functionality reduces the overall component count and simplifies the installation process

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

2Reliability

If a traditional hinge device with multiple pieces is used, then the rotatable coupling function is achieved, but the system becomes bulky

Engineering Contradiction:
Improverotatable coupling functionVSAvoidsystem bulkiness
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

By merging the hinge device and mounting plate into one integrated component, the patent significantly reduces the overall volume of the system. The combined structure eliminates gaps and redundant spaces between separate parts, creating a compact solution that maintains full rotational functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hinge mechanism is nested within the mounting plate structure, with the pivot and rotating elements contained within the plate's body. This nesting approach minimizes the external dimensions of the system while preserving the rotatable coupling function

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If a traditional hinge device with multiple pieces and fixing screws is used, then the rotatable coupling function is achieved, but the system becomes expensive

Engineering Contradiction:
Improverotatable coupling functionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The integration of multiple functions into a single mounting plate reduces the total number of parts that need to be manufactured, inventoried, and assembled. This consolidation lowers manufacturing complexity and material costs while maintaining the reliable rotatable coupling function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the essential function of rotation from the complex multi-component hinge system and implements it through a simplified mounting plate design. By taking out only the necessary rotational capability and integrating it directly into the mounting structure, the system achieves the required function at lower cost

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A rotating coupling system for a closing element (D), such as a door, window, door or the like, and a stationary support structure (S) such as a wall, floor, frame or the like comprising a hinge device (5) anchorable to the closing element (D) and a mounting plate (100) anchored to the stationary support structure (S). The hinge device (5) comprises a hinge body (10) and at least one pivot (20) defining a first axis (X) which is reciprocally coupled each other to rotate one with respect to the other around the axis (X). In particular, the pivot (20) includes at least one coupling portion (21) which protrudes from said hinge body (10) and the mounting plate (100) includes, respectively consisting of, a plate-shaped body (110) having at least one seat (111) for the coupling portion (21) of the pivot (20). The plate- shaped body (110) further includes means (140) for the adjusting of its position with respect to the stationary support structure (S).
