Removable Securement Arm for Head-Mountable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mountable devices face challenges in providing comfortable and reliable securement for users with varying head anatomies and engaging in different activities, as existing securement arms may not fit all users comfortably or securely.
Innovation Solution
The design includes removable securement arms with multiple portions, allowing users to swap out components for better fit and longer battery life, featuring electronic components like batteries and speakers distributed across the arm portions for balanced weight and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If securement arms are designed with fixed dimensions and shape, then manufacturing is simple, but they cannot accommodate users with varying head anatomies comfortably and reliably
Solution Approach 1:
The securement arm is divided into multiple portions (first portion, second portion, third portion) that can be independently configured and swapped. Each portion can have different dimensions, angles, and shapes to accommodate various head anatomies, while the modular design keeps manufacturing relatively simple through standardized connection interfaces.
Solution Approach 2:
The securement arm transitions from a fixed configuration to a dynamic, reconfigurable system where portions can be swapped and adjusted. Users can change the configuration of securement arm portions to adapt to different head shapes and sizes, providing versatility without requiring completely different devices for each user type.
2Adaptability or versatility
If securement arms are designed for a specific activity, then performance is optimized for that activity, but they become uncomfortable or insufficient for other activities
Solution Approach 1:
The securement arm is segmented into multiple portions that can be independently selected and combined. Users can choose different portions or configurations based on their activity (e.g., gaming, sports, working) to optimize comfort and performance for that specific activity while maintaining the ability to switch to different configurations for other activities.
Solution Approach 2:
The securement arm system is designed to serve multiple functions and activities through its modular portions. A single base device can support various securement arm configurations that are suitable for different activities, making the overall system universal rather than activity-specific.
3Adaptability or versatility
If electronic components are integrated into the securement arm, then the device becomes more functional, but the weight and size increase
Solution Approach 1:
Electronic components such as batteries and speakers are distributed across different portions of the securement arm rather than concentrated in one location. This segmentation allows for balanced weight distribution, reducing the weight burden on any single portion while maintaining full functionality. Users can also swap portions with different component configurations based on their needs.
Solution Approach 2:
Different portions of the securement arm have different functional characteristics and component distributions tailored to their specific locations and roles. This allows optimization of each portion for its intended function while managing overall weight and size constraints.

AI summary
A securement arm of an optical device can include a first portion and a second portion. The first portion can include a first housing defining a first internal volume and a first aperture and an electronic component disposed in the internal volume and positioned to fluidly communicate with an external environment through the first aperture. The second portion can be removably connected to the first portion and include a second housing defining a second internal volume and a second aperture and a securement mechanism. The second housing can receive the first housing into the second internal volume.
