Headset Panel Cleaning Case for External Sensor Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dirt, dust, and oil on the panels of head-mounted devices, such as virtual reality and augmented reality headsets, compromise the accuracy of external facing sensors, leading to a suboptimal user experience.
Innovation Solution
A storage case with a cleaner positioned to contact the panel and remove dirt, dust, and oil when the device is inserted or removed, and a notification system to inform the user when cleaning is needed and complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the panel is cleaned manually by the user, then the sensor accuracy is maintained, but the user experience is degraded due to the inconvenience and reminder notifications
Solution Approach 1:
The storage case is equipped with an automated cleaning mechanism that cleans the panel automatically when the device is placed in the case, eliminating the need for manual user intervention and maintaining sensor accuracy without requiring user action or attention
2Extent of automation
If a storage case with cleaner is provided, then the cleaning function is automated, but the device complexity increases
Solution Approach 1:
The cleaning function is integrated into the existing storage case structure, combining the storage and cleaning functions into a single unit. The cleaner is positioned within the case cavity and activated automatically when the device is placed in the case, merging multiple functions without requiring separate independent systems
3Device complexity
If the panel is not cleaned regularly, then the device structure remains simple, but the sensor accuracy deteriorates
Solution Approach 1:
The cleaning action is performed automatically each time the device is stored in the case, preventing dirt and oil accumulation before they can significantly degrade sensor accuracy. The cleaner is positioned to contact the panel and remove contaminants proactively during normal storage operations

AI summary
A head-mounted device includes an external facing sensor configured to generate a signal corresponding to a characteristic of an external environment. A controller is configured to determine that a quality of the signal is below a threshold value and take an action in response. Another embodiment includes a case for storing a head-mounted device that includes a cleaner coupled with a base or a lid of case. The cleaner is configured to clean a portion of the head-mounted device when the head-mounted device is inserted into and/or removed from the case.
