Head-Mounted Battery Layout for Stable Upright and Reclining Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted electronic devices with front-mounted batteries experience stability issues when transitioning between upright and reclining states due to the center of gravity shifting, affecting wearing comfort and stability.
Innovation Solution
A head-mounted electronic device design featuring a detachable battery connection system, allowing the battery to be mounted on either the device body or a functional part opposite to the body, adjusting the center of gravity based on user posture, with a secondary battery for continuous power during state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is front-mounted to facilitate reclining state usage, then the quantity and thickness of components at the rear are reduced, but the device becomes unstable when used in upright or sitting states
Solution Approach 1:
The battery mounting position is made adjustable rather than fixed, allowing the device to adapt its center of gravity based on usage posture. The battery can be dynamically repositioned between front and rear mounting locations to optimize stability for different states (reclining vs. upright/sitting).
Solution Approach 2:
The position parameter of the battery is changed between two discrete locations (front and rear) to alter the device's center of gravity. This parameter change allows the device to transition from a fixed configuration to a configurable one, resolving the stability conflict between different usage states.
2Stability of the object's composition
If the battery is rear-mounted to balance the device in upright state, then wearing stability is improved, but the device becomes less comfortable when used in reclining state due to increased components at the rear
Solution Approach 1:
The battery mounting position is made adjustable rather than fixed, allowing the device to adapt its center of gravity based on usage posture. The battery can be dynamically repositioned between front and rear mounting locations to optimize stability for different states (reclining vs. upright/sitting).
Solution Approach 2:
The position parameter of the battery is changed between two discrete locations (front and rear) to alter the device's center of gravity. This parameter change allows the device to transition from a fixed configuration to a configurable one, resolving the stability conflict between different usage states.
3Device complexity
If the battery is fixed in one position, then the device structure is simplified, but the device cannot adapt to different usage states
Solution Approach 1:
The battery mounting system is designed with multi-functionality, allowing the same battery to serve in different positions (front or rear) depending on usage requirements. The mounting structure incorporates multiple mounting locations and a switching mechanism, enabling one component to fulfill multiple functional roles across different usage scenarios.
Solution Approach 2:
The battery mounting position is made adjustable rather than fixed, allowing the device to adapt its center of gravity based on usage posture. The battery can be dynamically repositioned between front and rear mounting locations to optimize stability for different states (reclining vs. upright/sitting).
