Screwless Fan Device With Trigger-Actuated Elastic Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan devices for electronic devices require screw assembly, which can be cumbersome and inconvenient for disassembly, especially in scenarios where frequent maintenance or replacement is necessary.
Innovation Solution
A fan device designed for assembly to a chassis without screws, utilizing a clip with an elastic part, engagement part, pressed part, handle, and trigger, allowing for easy engagement and disengagement by pressing the trigger with a single finger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw assembly is used for fan device installation, then the connection strength and reliability are improved, but the ease of operation and maintenance become worse
Solution Approach 1:
The clip employs an elastic part that can dynamically change its state between engaged and disengaged positions. The elastic part is biased by an elastic force to maintain engagement, but can be temporarily deformed by applying force to the trigger, allowing the engagement part to move between engaged and disengaged states relative to the chassis engagement slot.
Solution Approach 2:
The connection mechanism is segmented into distinct functional parts: the elastic part for maintaining force, the engagement part for mechanical interlocking, and the trigger for actuation. This segmentation allows each part to perform its specific function efficiently while enabling easy control through the trigger mechanism.
2Stability of the object's composition
If screw assembly is used for fan device installation, then the structural stability is improved, but the device complexity and time consumption for maintenance increase
Solution Approach 1:
The elastic part automatically maintains the engagement part in the engaged position through elastic force, providing self-locking without requiring additional fastening operations. The trigger mechanism allows single-handed operation for disengagement, reducing the need for complex tools or multi-step procedures.
Solution Approach 2:
The elastic part acts as an intermediary that translates the simple trigger actuation into sustained engagement force. When the trigger is released, the elastic part automatically restores the engagement part to the engaged position, mediating between the user's brief input and the continuous connection requirement.
3Strength
If screw assembly is used for fan device installation, then the connection strength is improved, but the productivity and efficiency of device replacement decrease
Solution Approach 1:
The elastic part is pre-loaded with elastic force that continuously pushes the engagement part into the engaged position. This preliminary action ensures that the connection is already established and maintained before any disassembly operation begins, allowing for rapid re-engagement simply by releasing the trigger.
Solution Approach 2:
The connection mechanism transitions from a static screwed state to a dynamic spring-loaded state that can be quickly activated and deactivated. The elastic part's ability to rapidly deform and restore enables fast cycling between engaged and disengaged states, dramatically improving replacement efficiency.
