Docking Hook Mechanism Prevents Tablet Casing Abrasion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet computer docking systems cause abrasion on the casing surface during device placement due to the protrudent hook mechanism, compromising aesthetics and having a complex structure that is not user-friendly.
Innovation Solution
An electronic device bearing seat with a casing, hooks, resilient elements, an ejector, pivot, connecting rod, and ejecting button, where the hook and ejector move perpendicular to each other, allowing for secure attachment and easy detachment without direct pressure on the casing, utilizing torsion springs for resilience and a simplified structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protrudent hook is used to fasten the tablet computer, then the device can be securely fastened to the docking, but the casing surface of the tablet computer is abraded during the placing process
Solution Approach 1:
Instead of having the hook protrude outward to engage with the device, the patent inverts the approach by having the hook remain retracted within the docking body. The hook only protrudes when actively ejected by the resilient element to engage with the fastening hole, thereby avoiding continuous contact that causes abrasion while maintaining fastening reliability when needed.
Solution Approach 2:
The resilient element is pre-loaded in a compressed state before use, storing elastic potential energy. When the hook needs to be ejected, the resilient element automatically pushes the hook outward without requiring additional force from the user,从而实现 the fastening action in advance preparation.
2Reliability
If a protrudent hook mechanism is used, then the device can be fastened securely, but the structure becomes complicated and prone to losing effectiveness
Solution Approach 1:
The patent combines multiple functions into the hook component: it serves as both the fastening element and the ejection target. The same hook that engages with the fastening hole is also pushed by the resilient element for ejection, eliminating the need for separate actuating mechanisms and simplifying the overall structure.
Solution Approach 2:
The resilient element automatically provides the ejection force needed to retract the hook after it has served its fastening purpose. This self-service mechanism eliminates the need for additional motors, solenoids, or manual intervention to reset the hook, thereby reducing structural complexity while maintaining reliable fastening and release functionality.
