Wearable Electronic Housing With Flush Display Cover Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices face challenges in balancing portability with performance due to the inclusion of multiple components, which can limit functionality and durability, especially in varying environments and conditions.
Innovation Solution
The design incorporates a housing with tailored arrangements of components, including a transparent display cover flush with the peripheral edge, protrusions for buttons and dials, and strategically positioned speaker vents, along with an epoxy seal and non-conductive materials to prevent moisture ingress, while maintaining electrical connectivity and antenna performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are included to enhance functionality, then device performance is improved, but device portability and compactness deteriorate
Solution Approach 1:
The patent combines multiple components (display, buttons, speakers, sensors) into a single integrated wearable device housing. The housing integrates the transparent display cover, crown, buttons, and dual speakers into one compact unit, allowing enhanced functionality without proportionally increasing device volume. This merging approach enables the device to perform multiple functions while maintaining portability.
Solution Approach 2:
The patent employs nested arrangement where components are positioned within the housing in a space-efficient manner. The crown and buttons are recessed into the housing sidewall, speakers are positioned within internal volumes, and the transparent display cover is integrated into the housing opening. This nesting allows multiple components to coexist in a compact form factor.
2Adaptability or versatility
If components are positioned to maximize functionality, then device performance is improved, but device reliability deteriorates due to increased exposure to environmental factors
Solution Approach 1:
The patent applies preliminary protective measures by recessing the crown and buttons into the housing sidewall, creating physical barriers that prevent inadvertent contact and exposure to environmental factors before damage can occur. The transparent display cover is positioned with its outward facing surface level with the upper peripheral edge, providing inherent protection. These design features proactively protect components while maintaining full functionality.
3Adaptability or versatility
If speaker vents and apertures are created for audio functionality, then device versatility is improved, but device reliability deteriorates due to moisture ingress risk
Solution Approach 1:
The patent employs the housing sidewall structure as a protective barrier that incorporates speaker vents and apertures while maintaining moisture protection. The housing acts as a flexible barrier that allows acoustic functionality through controlled openings while preventing moisture ingress to internal components. This enables audio functionality without compromising the protective enclosure.

AI summary
An electronic device includes a housing sidewall defining an opening and a display component, such as a display cover, disposed in the opening to form a gap between the housing sidewall and the display component. In at least one example, the cavity is defined by the sidewall and the display cover with the cavity in fluid communication with an external environment through the gap. In at least one example, an epoxy component at least partially defines the cavity and can be in direct contact with the housing sidewall.
