Solution Overview

Problem

Prior window operator handles and covers face issues with dirt and dust accumulation, difficulty in engaging the handle properly, cluttered aesthetics, and challenging detachment due to mechanical securing methods.

Innovation Solution

The use of magnetic features to secure the handle on the operator cover, eliminating the need for mechanical projections or recesses, allowing for easier grasping and smoother operation, and enabling easy detachment of the cover from the operator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mechanical securing features (projections or recesses) are used to hold the handle, then the handle can be secured in place, but dirt and dust accumulate in the features and the appearance becomes cluttered

Engineering Contradiction:

Improvehandle securingVSAvoiddirt and dust accumulation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical securing features (projections and recesses) with magnetic attraction to hold the handle in place. The handle portion contains a magnet that is attracted to the operator cover, providing secure retention without requiring physical interlocking features that would trap dirt and dust. This substitution eliminates the cluttered appearance while maintaining reliable handle securing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If mechanical pins or latches are used to attach the operator cover, then the cover can be securely attached, but detachment becomes difficult and components can be inadvertently broken

Engineering Contradiction:

Improvecover attachmentVSAvoidcover detachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical attachment methods (pins, latches, or snaps) with magnetic attraction to secure the operator cover to the operator. The magnet in the handle portion is attracted to the operator cover, and the cover itself is magnetically attracted to the operator, providing secure attachment that can be easily detached by simply pulling away. This eliminates the risk of breaking fragile mechanical components while maintaining reliable attachment.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the handle is received in a recess of the cover, then the handle can be secured, but users have difficulty grasping the handle to extract it for operation

Engineering Contradiction:

Improvehandle positioningVSAvoidhandle grasping

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the recess-based mechanical retention system with magnetic attraction. The handle portion contains a magnet that is attracted to the operator cover, allowing the handle to be securely positioned without being embedded in a recess. This enables users to easily grasp the handle with their fingers and extract it for operation, while the magnetic force automatically re-secures the handle when folded back into position.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If folding handles are held in closed position by physical ledges or pockets, then the handle can be retained, but the aesthetic appearance becomes cluttered

Engineering Contradiction:

Improvehandle retentionVSAvoidaesthetic appearance

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent replaces physical ledges and pockets with magnetic attraction to retain the folding handle in its closed position. The magnet in the handle portion is attracted to the operator cover, providing invisible retention that does not require visible mechanical features. This maintains a clean, sleek aesthetic appearance while ensuring reliable handle retention during normal operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
