Solution Overview

Problem

Existing hinges with three coaxial hinging elements require complex assembly processes and lack easy adjustment mechanisms, making them difficult to install and adjust without disassembling components.

Innovation Solution

A hinge design featuring a central hinging element with sliding pivoting means and adjustment screws, allowing terminal hinging elements to be assembled independently and adjusted in multiple directions without disassembly, with clamping elements for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If pins are inserted through terminal hinging elements into the central hinging element, then the hinge structure is assembled, but the assembly process becomes complex and time-consuming

Engineering Contradiction:

Improveassembly simplicityVSAvoidassembly time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

Instead of inserting pins from terminal elements into the central element (complex multi-directional assembly), the patent inverts the approach by having the central hinging element insert into the terminal elements through guide members. This allows assembly from one direction only, simplifying the manufacturing process and reducing assembly time significantly.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If the hinge structure is fixed during assembly, then structural stability is achieved, but adjustment of mobile element position becomes difficult

Engineering Contradiction:

ImproveadjustabilityVSAvoidstructural stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent incorporates adjustment means including threaded rods and clamping elements that allow the hinge to transition from a fixed stable state during installation to an adjustable state for positioning, and then back to a fixed stable state once adjusted. This dynamic capability enables both structural stability and ease of operation at different stages of use.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple adjustment mechanisms are added to enable position adjustment, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveposition adjustment capabilityVSAvoidhinge structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment means are integrated into the existing hinge structure components. The threaded rods, clamping elements, and guide members serve multiple functions: they enable position adjustment, maintain structural stability, and guide the insertion motion. This multi-functionality provides adaptability without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A hinge (10) for hinging a mobile element (11) with respect to a fixed structural element (12) and comprising a central hinging element (13) having a pivoting axis (X) and two terminal hinging elements (14, 15) configured to be disposed on reciprocally opposite sides and with play with respect to the central hinging element (13), coaxially to the pivoting axis (X). The central hinging element (13) comprises a first cavity in which a first pivoting mean (23) is slidingly disposed, mobile parallel to the pivoting axis (X) between an inactive position in which it is substantially inside the cavity, and an operating position in which it protrudes operatively from the cavity so that it can be selectively inserted into a corresponding first guide member of one of the two terminal hinging elements (14).
