Retractable Smartwatch Display With Impact-Recess Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable display devices, such as smartwatches, are fragile and susceptible to cosmetic damage like scratches and cracks, necessitating protective cases or covers, which may not be aesthetically pleasing for consumers.
Innovation Solution
The implementation of a system that allows the display of wearable devices to automatically retract into a recessed configuration within the device body when danger is detected, using electromagnets and mechanical locks to control the display's position, thereby protecting it from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is kept in an exposed configuration for user access, then ease of operation is improved, but the display becomes susceptible to cosmetic damage such as scratches and cracks
Solution Approach 1:
The display is designed to dynamically change its position between exposed and recessed configurations based on detected danger conditions. The display can be moved from a vulnerable exposed state to a protected recessed state within the device body, allowing the system to adapt its physical configuration in response to environmental threats while maintaining user accessibility when safe
Solution Approach 2:
The system applies preliminary protective action by retracting the display into the device body before actual damage can occur. Danger detection triggers the retraction mechanism in advance, creating a protective state that prevents cosmetic damage before it happens rather than responding after damage occurs
2Reliability
If protective cases or covers are used to preserve the display, then reliability is improved, but the device complexity and aesthetics are worsened
Solution Approach 1:
The protective function is merged with the device body itself. Instead of adding separate protective cases or covers as external components, the device body is designed to accommodate the display in a recessed configuration, integrating the protection mechanism into the core structure. This eliminates the need for additional protective accessories while maintaining display safety
Solution Approach 2:
The display is extracted from the fixed exposed position and made movable into the device body. By separating the display from its traditional permanent surface mounting and enabling it to be retracted inward, the solution removes the need for external protective cases while providing inherent protection through the device's own structure

Data Source
AI summary
A device's display can be moved based on sensor data to protect the display. The display can be moved via springs and/or electromagnets. The display can be moved into a safe recessed position, allowing a frame to absorb impacts that might otherwise damage the display. The display can also be moved back out of the recessed position.
