Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing door and window closing systems face issues such as wear and noise due to roller latches, and aesthetic limitations from visible mechanical components, while also being constrained by the need for a handle for unlocking.

Innovation Solution

A door or window system utilizing a magnetic induction closing catch and mechanical dead bolt locking mechanism, where the magnetic catch retains the panel in the closed position, allowing for handle-free operation and reducing wear, with the dead bolt ensuring secure closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a roller latch is used to close the panel, then the closing function is achieved, but wear and noise increase progressively

Engineering Contradiction:

ImprovedurabilityVSAvoidwear and noise

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical roller latch system with a magnetic closing catch system. The magnetic catch uses magnetic attraction forces to retain the panel in the closed position without mechanical contact between moving parts, thereby eliminating wear and noise while maintaining the closing function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state of the locking mechanism from mechanical contact to magnetic field interaction. By using magnetic forces instead of mechanical rollers, the system achieves the same closing function without the harmful effects of friction and impact.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If a handle is directly mounted on the lock latch for unlocking, then the unlocking function is achieved, but the design flexibility is limited

Engineering Contradiction:

Improveunlocking functionVSAvoiddesign flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent separates the handle function from the locking mechanism. The handle is mounted independently on the panel, while the magnetic catch and dead bolt are separate components. This segmentation allows the handle to be positioned and designed independently, enhancing design flexibility while maintaining the unlocking function through the dead bolt mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a dead bolt as an intermediary mechanical locking component that works independently of the magnetic catch. The dead bolt provides a reliable mechanical lock that can be actuated by the handle, while the magnetic catch provides the closing force. This intermediary mechanism allows for greater design freedom in handle placement and styling.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If a roller latch is exposed to view in the open configuration, then the closing mechanism is visible, but the aesthetic pleasantness is limited

Engineering Contradiction:

Improvevisibility of mechanismVSAvoidaesthetic pleasantness

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The patent replaces the visible mechanical roller latch with a magnetic catch system that can be more easily concealed. The magnetic catch components can be integrated into the panel and frame structures, allowing for cleaner lines and better aesthetics when the door or window is open, while still providing reliable closing functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
