Slidable Body Coupling Structure for Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable electronic devices are vulnerable to damage from external impacts, such as accidental drops, due to their extended design which limits their operational reliability.
Innovation Solution
A coupling structure is implemented to separate the slidable body from the main body upon impact, allowing for easy recovery and preventing damage, which includes a nut frame with a latch protrusion and a locker with a latch groove that separates when an external impact is detected, enabling the slidable body to retract within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slidable body is extended from the housing to enable functional operations, then the functionality and versatility of the device are improved, but the device becomes vulnerable to damage from external impacts such as drops
Solution Approach 1:
The device is divided into separable parts: a main body and a slidable body that can be detached from each other. The coupling structure allows the slidable body to be separated from the main body upon impact detection, preventing damage propagation between components while maintaining functional versatility during normal operation
Solution Approach 2:
The coupling structure is pre-configured with separation capability before impact occurs. The latch mechanism and escape area are designed in advance to enable automatic separation when impact is detected, rather than requiring post-impact repair or manual intervention
2Reliability
If a coupling structure is designed to separate upon impact to prevent damage, then the reliability is improved, but the device complexity increases due to additional components like latch protrusions and escape areas
Solution Approach 1:
The coupling structure integrates multiple functions into a unified design: the latch protrusion and latch groove serve both as connection elements during normal operation and as separation elements upon impact. The escape area is combined with the coupling structure itself rather than being a separate component, reducing overall structural complexity while maintaining reliability
Solution Approach 2:
The coupling structure performs multiple functions: it connects the slidable body to the main body during normal operation, detects impact conditions through the latch mechanism, and enables separation when needed. This multi-functionality reduces the need for additional dedicated components for each function

AI summary
According to certain embodiments, an electronic device may include a housing, a slidable body; a driver including: a drive motor, a rotatable drive shaft for the drive motor, and a nut frame including a latch projection, protruding in a direction of the slidable body, and a slide hinge disposed on the slidable body and coupled to the driver, wherein the slide hinge includes: a slide plate coupled to the slidable body, and a locker including a latch groove, into which the latch protrusion is inserted, wherein, when the latch projection is inserted into the latch groove, the slidable body is moved by the driver, and wherein the slide plate defines an escape area configured to receive at least a portion of the nut frame and/or the latch protrusion, when an external impact causes the latch protrusion to separate from the latch groove.
