Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing swivel fittings for doors and windows lack a simple and effective method for securely fixing the carrier part to the frame, limiting adjustability and durability.

Innovation Solution

The carrier part is made to be longitudinally displaced within limits relative to a metal base rail with angled guide webs and anchor webs, ensuring a secure connection by engaging behind the base rail's openings, allowing for easy adjustment and guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the carrier part is rigidly fixed to the base rail, then the connection strength is improved, but the adjustability of the swivel fitting is lost

Engineering Contradiction:

Improveconnection strengthVSAvoidadjustability

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The connection between the carrier part and base rail is made dynamically adjustable through the guide web and anchor web mechanism. The carrier part can be positioned at different locations along the base rail and fixed in place, providing both movement capability and stable fixation when needed.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the carrier part is made adjustable relative to the base rail, then the adaptability is improved, but the connection strength is reduced

Engineering Contradiction:

ImproveadjustabilityVSAvoidconnection strength

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The anchor webs are designed to be pushed through the guide webs in advance, and the base rail is pre-formed with recesses that will engage the anchor webs. This preliminary preparation ensures that when the carrier part is adjusted to its final position, the connection strength is immediately maximized without requiring additional fastening operations.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If a complex fixing mechanism is used to secure the carrier part to the frame, then the reliability is improved, but the device complexity increases

Engineering Contradiction:

Improvefixing reliabilityVSAvoidfixing mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fixing mechanism is designed to be self-securing through the interaction between the guide webs, anchor webs, and base rail recesses. Once the carrier part is positioned and the anchor webs are pushed through the guide webs, the base rail's recesses automatically engage the anchor webs to lock the position, eliminating the need for separate fastening components or complex assembly procedures.

Inventive Principle:

Principle #25Self-service

4Strength

If the base rail openings are made small for secure engagement, then the connection strength is improved, but the ease of manufacture deteriorates

Engineering Contradiction:

Improveengagement strengthVSAvoidmanufacturing ease

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The base rail is pre-formed with recesses in the appropriate locations before the carrier part is assembled. This preliminary preparation allows the anchor webs to be simply pushed through the guide webs and into the pre-positioned recesses, ensuring strong engagement without requiring complex post-assembly operations or precision drilling of small holes.

Inventive Principle:

Principle #10Preliminary action
