Adjustable Actuator Housing for Window Linkage Alignment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The alignment between motorized actuators and their linkages on fixed and movable window portions often results in misalignment issues, leading to improper window closure, water, air, and noise intrusion, and potential security risks, especially in large windows with multiple actuators, due to imprecise mounting and thermal expansion.

Innovation Solution

A housing system with adjustable features allows for precise alignment of the actuator within its cavity, utilizing brackets and clamping plates that enable the actuator to be laterally positioned and secured, ensuring proper alignment with the window linkage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the actuator is mounted recessed into the fixed frame part of the window, then the mounting is less exposed and more aesthetically pleasing, but misalignment between the actuator linkage and the linkage on the movable portion becomes more difficult to detect and correct

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidalignment detection

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The housing includes adjustment mechanisms that allow preliminary alignment adjustments to be made before final mounting, enabling proper alignment to be achieved even when the actuator is recessed and difficult to access during operation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The housing acts as an intermediary component between the actuator and the window frame, providing adjustment mechanisms that facilitate alignment while maintaining the recessed mounting configuration

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the actuator is mounted with tight tolerances for proper operation, then the window closure is more reliable, but the complexity of the mounting process increases due to the need for precise alignment

Engineering Contradiction:

Improvewindow closure reliabilityVSAvoidmounting complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The housing incorporates adjustable components that allow the actuator position to be dynamically adjusted during mounting, enabling tight tolerances to be achieved without requiring complex pre-machining or pre-alignment procedures

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The adjustment mechanisms allow positional parameters of the actuator to be changed during installation, enabling proper alignment to be achieved through adjustment rather than through complex manufacturing processes

Inventive Principle:

Principle #35Parameter changes

3Productivity

If multiple actuators are used on large windows, then the window can be operated more effectively, but misalignment between actuators can cause out-of-plane bending forces that may break the glass

Engineering Contradiction:

Improvewindow operation effectivenessVSAvoidout-of-plane bending forces

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The housing allows independent adjustment of each actuator's position and orientation parameters, enabling multiple actuators to be precisely aligned to work together without creating harmful out-of-plane bending forces on the glass

Inventive Principle:

Principle #35Parameter changes
