Wearable Display Arm Structure for Seamless Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Batteries in head-mountable electronic devices are often positioned in securing arms, compromising their replaceability due to design tensions with the device's aesthetics and user comfort.
Innovation Solution
A wearable display device with a securement arm that allows batteries to be removed seamlessly, maintaining electrical connections and a seamless housing exterior, enabling easy replacement without disrupting the device's aesthetic or comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the battery is positioned in the securing arm to maintain a seamless housing exterior, then the aesthetic appearance is improved, but the replaceability of the battery deteriorates
Solution Approach 1:
The securing arm is divided into multiple segments: a fixed portion attached to the housing and a removable portion containing the battery. This segmentation allows the battery to be accessed and replaced by removing only the distal portion, while the proximal portion remains attached to maintain the seamless appearance of the housing exterior.
Solution Approach 2:
The battery and its housing are extracted as a separate removable component from the main securing arm structure. The battery housing is detachably coupled to the securing arm, allowing the battery to be taken out for replacement without disturbing the integrated appearance of the main housing.
2Stability of the object's composition
If the battery is positioned in the securing arm to maintain device integrity, then the structural stability is improved, but the accessibility of the battery deteriorates
Solution Approach 1:
The securing arm is segmented into a fixed proximal portion and a removable distal portion. The battery is housed in the distal portion which can be detached from the proximal portion, providing easy accessibility for battery replacement while maintaining device integrity when assembled.
Solution Approach 2:
A removable battery housing acts as an intermediary component between the battery and the main securing arm structure. This intermediate element provides a convenient interface for battery access and replacement, while the securing arm itself maintains its structural integrity and seamless appearance.
3Shape
If the securing arm is designed as a singular seamless shell for aesthetic purposes, then the visual appearance is improved, but the ease of manufacturing deteriorates
Solution Approach 1:
The seamless shell is segmented into multiple manufacturable components: a proximal securing arm portion and a distal battery housing portion. These segments can be manufactured separately using standard manufacturing processes, then assembled to create the appearance of a seamless shell, thereby improving ease of manufacture while maintaining aesthetic appearance.
Solution Approach 2:
The battery housing is nested within or coupled to the securing arm structure. This nesting arrangement allows the battery compartment to be integrated into the seamless shell design while enabling independent manufacturing and assembly of the battery housing from the main securing arm components.

AI summary
A wearable display device can include, a display frame, a securement arm, a battery, a speaker, and a printed circuit board (PCB). The securement arm of the device can have a proximal end and removably couple to the display frame and a distal end opposite the proximal end, and the securement arm can define a singular seamless shell. The PCB can couple to the battery and electrically couple to the speaker via an electrical conductor. The length of the conductor being greater than a distance between the PCB and the speaker within the shell. The shell defines an opening at the proximal end of the arm through which the battery and the PCB can be removed together without interrupting the electrical connection between the PCB and the speaker via the conductor.
