Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing window operator handles and covers face issues with dirt and dust accumulation, difficulty in engaging the handle properly, and a cluttered aesthetic due to mechanical securing methods, as well as challenges in detaching and reattaching the operator cover.

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 positioning, and enabling the cover to be easily detached with magnets, along with a detent mechanism to retain the handle in the unfolded position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:

Improvehandle attachment securityVSAvoiddirt 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 cover, eliminating the need for mechanical interlocking features. This substitution resolves the contradiction by maintaining secure attachment while eliminating surfaces where dirt and dust can accumulate.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

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

Engineering Contradiction:

Improvecover attachment securityVSAvoidcover attachment manipulation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical pins or latches with magnetic attraction to attach the operator cover to the operator. The magnetic connection allows the cover to be securely attached while enabling easy manipulation - the cover can be attached by simply bringing it near the operator and detached by pulling it away, eliminating the complexity and fragility of mechanical fastening mechanisms.

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 in place, but the user has difficulty grasping the handle to extract it from the recess

Engineering Contradiction:

Improvehandle positioningVSAvoidhandle grasping and extraction

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent eliminates the recess structure by using magnetic attraction to position and secure the handle. The magnet in the handle portion is attracted to the cover, providing secure positioning without requiring the handle to be received in a recess. This allows the user to easily grasp and extract the handle from any position on the cover surface.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If mechanical securing features are used on the handle and cover, then the handle can be held in the closed position, but the aesthetic appearance becomes cluttered

Engineering Contradiction:

Improvehandle position maintenanceVSAvoidaesthetic appearance

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent replaces visible mechanical securing features with magnetic attraction, allowing the handle and cover to have smooth, clean surfaces without protruding projections or recesses. The magnetic connection maintains the handle in the closed position while preserving aesthetic appearance by eliminating cluttered mechanical features.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
