Box fan securing devices and methods of making and using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively secure box fans to window sashes, leading to instability and potential damage or noise issues.
Innovation Solution
The development of box fan securing devices with adjustable sash-contacting and fan-contacting members that can be integrated with or attached to the fan, allowing for secure positioning between the fan and window sash edges, utilizing various components such as base, front, and top components with movable parts for optimal fit and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing securing solutions are used, then installation is simple, but the box fan becomes unstable and produces noise
Solution Approach 1:
The securing device is divided into multiple independent components: a window sash contacting member, a fan contacting member, and a connecting member. These segmented parts can be independently positioned and adjusted to fit different window and fan configurations, providing stable attachment without requiring an overly complex integrated structure.
Solution Approach 2:
The connecting member includes adjustable and movable features that allow the securing device to adapt dynamically to different fan sizes and window sash dimensions. This dynamic adjustability ensures reliable stabilization across various configurations without needing multiple fixed-size devices.
2Adaptability or versatility
If fixed-size securing devices are used, then manufacturing is simple, but they cannot accommodate different fan and window sizes
Solution Approach 1:
The connecting member is designed with adjustable length capabilities and movable connection points, allowing the same device to accommodate various distances between window sashes and fans of different sizes. This dynamic design provides versatility without requiring completely different devices for each size configuration.
Solution Approach 2:
The securing device is designed as a universal solution that can attach to different window sash types and fan models through its adjustable connecting member. The same basic structure serves multiple functions across different application scenarios, balancing manufacturing simplicity with adaptability.
3Reliability
If existing securing methods are used, then installation is quick, but movement and noise occur during operation
Solution Approach 1:
The segmented design allows each component (window sash contacting member, fan contacting member, connecting member) to be independently installed and positioned, enabling quick assembly while ensuring stable attachment that prevents movement during fan operation.
4Adaptability or versatility
If a single integrated securing component is used, then device complexity is low, but it cannot provide optimal fit for different configurations
Solution Approach 1:
By dividing the securing device into three functional segments, the design achieves adaptability to different configurations while keeping each individual component relatively simple in structure.
Solution Approach 2:
The three segmented components are designed to work together as an integrated system, combining simplicity of individual parts with the adaptability of the complete assembly across different fan and window configurations.
