Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional connectors use hinged half-shells or separate rings for fixing hoses, then the hose can be secured, but the device complexity increases and ease of operation decreases

Engineering Contradiction:
Improveease of useVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the hose clamping function and the connector body into a single integrated structure. The clamping element is formed as an integral part of the connector body, eliminating the need for separate fixing rings or hinged half-shells. This merging of functions reduces the number of components and simplifies the overall device structure while maintaining effective hose securing capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamping element is designed to automatically grip and secure the hose when the connector is assembled. The elastic deformation of the clamping element creates a self-locking mechanism that holds the hose in place without requiring additional fastening operations or complex adjustment mechanisms, thereby improving ease of operation.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If conventional connectors lack protective structures, then the device complexity remains low, but the hose is vulnerable to external forces and environmental agents

Engineering Contradiction:
Improveprotection from external forcesVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective features are integrated into the connector body structure itself. The contoured recess and inclined surface are formed as integral features of the connector, providing mechanical protection for the hose insertion area while maintaining a compact, unified design. This approach adds protection without requiring separate protective components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamping element acts as a flexible protective structure that surrounds and secures the hose. Its elastic nature allows it to conform to the hose shape while providing mechanical protection against external forces, effectively serving as both a securing and protective mechanism.

Inventive Principle:
Principle #30Flexible shells and thin films

3Ease of manufacture

If conventional connectors use multiple separate components for fixing, then the hose can be securely fixed, but the manufacturing cost and implementation complexity increase

Engineering Contradiction:
Improveease of manufactureVSAvoidsecure locking
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

By forming the clamping element as an integral part of the connector body through injection molding or similar manufacturing processes, the patent reduces the number of assembly steps and potential failure points. The unified structure ensures consistent manufacturing quality while maintaining reliable hose securing through the elastic clamping mechanism.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastic clamping element provides self-locking functionality through its inherent elastic deformation characteristics. When the connector is assembled, the clamping element automatically deforms to grip the hose and maintains this grip through its elastic recovery force, ensuring secure locking without requiring additional locking mechanisms or complex assembly procedures.

Inventive Principle:
Principle #25Self-service

AI summary

A connector (1) for hoses and the like, which comprises a main body (10) and a fixing ring (20) which is adapted to be coupled mechanically to the main body (10) in a coupling condition in which the fixing ring (20) and the main body (10) form a complete body of the connector (1) which defines inside it a through tunnel (5) which extends along a longitudinal axis (Y) and which is configured to accommodate one end of a hose (9) or the like; the main body (10) comprises a contoured fixing recess (60) and an inclined surface (17) which is internal to the main body (10); the fixing ring (20) comprises: - a plurality of engagement fingers (30) which protrude longitudinally and are transversely flexible in the direction of the longitudinal axis (Y) at least up to a fixing configuration in which they engage the hose (9), thus preventing its movement out of the connector (1); - one or more fixing pins (22) which in the coupling condition each occupy a respective contoured fixing recess (60); the inclined surface (17) being configured to interact mechanically with the engagement fingers (30) so as to induce the bending thereof toward the fixing configuration when the fixing ring (20) is moved along the longitudinal axis (Y).
