External Connection Apparatus for Head-Mounted Digital Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted digital devices with displays are bulky and heavy, causing discomfort and physical pain during prolonged use, especially due to the lack of effective external connection solutions that can alleviate the head burden.
Innovation Solution
An external connection apparatus comprising a support plate, a strap, and a soft cushion layer, which allows the weight of the head-mounted digital device to be transferred away from the head, providing shock absorption and protection while allowing for comfortable and stable use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the head-mounted digital device with display is designed as a wearable all-in-one unit, then the device integrates all necessary components (display, CPU, sensors, etc.) in a compact form, but the device becomes heavy and causes head burden and physical discomfort during prolonged use
Solution Approach 1:
The device is divided into two parts: a lightweight head-mounted unit containing only essential components (display, optical components, sensors) and a separate external support unit that carries the heavy components (main circuit board, CPU, battery, storage). This segmentation resolves the contradiction by maintaining device integration functionality while eliminating head burden.
Solution Approach 2:
The heavy and complex components (main circuit board, CPU, battery, storage unit) are extracted from the head-mounted unit and placed in an external support unit. This extraction allows the head-mounted device to remain lightweight and comfortable for prolonged wear while still maintaining full functionality through the external unit.
2Ease of operation
If external support solutions like buckles are added to transfer device weight to extracorporeal support, then head comfort is improved, but the buckle becomes prone to breakage due to concentrated force and contact difficulty
Solution Approach 1:
The support plate is designed with a large surface area that distributes the device weight across multiple contact points on the head, rather than concentrating force at a single buckle point. This local quality improvement enhances both comfort and reliability by reducing stress concentration.
Solution Approach 2:
A soft cushion layer is introduced as an intermediary between the support plate and the head-mounted device. This cushion layer acts as a mediator that absorbs shock and distributes pressure evenly, preventing the concentrated force that causes buckle breakage while maintaining head comfort.
3Reliability
If the support structure is made rigid to ensure stability and durability, then the structure can bear the device weight reliably, but it becomes uncomfortable and causes pain during prolonged use
Solution Approach 1:
The support plate is designed with flexible properties, allowing it to adapt to the contours of the head and distribute pressure evenly. This flexibility maintains structural stability for bearing device weight while ensuring comfort during prolonged use by preventing pressure points and pain.
Solution Approach 2:
The soft cushion layer serves as an intermediary between the rigid support structure and the user's head. It provides shock absorption and pressure distribution, enabling the rigid structure to maintain stability while the cushion ensures comfort during extended wear.
