Headlamp Battery Segmentation for Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Headlamps used in various conditions face discomfort due to increased weight from larger batteries, which affects long-term wearability.
Innovation Solution
A headlamp design comprising separate light, battery, and booster units, where the battery unit is positioned at the back of the head, and the booster unit can be selectively attached to provide additional power, with integrated lights and controls, and a power port for external devices, allowing for enhanced visibility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a larger battery is used to provide more power, then the power capacity is improved, but the weight increases making the headlamp less comfortable to wear
Solution Approach 1:
The battery system is divided into two separate units: a primary battery unit integrated into the headlamp and a removable booster unit. This segmentation allows the user to carry only the necessary power capacity for each specific use, reducing unnecessary weight while maintaining the option for extended power when needed.
Solution Approach 2:
The battery configuration is made dynamic and adaptable through the removable booster unit that can be attached or detached based on power needs. The system transitions from a fixed battery size to a flexible configuration where the effective battery capacity can be adjusted, allowing users to optimize between weight and power capacity for different outdoor activities.
2Duration of action of stationary object
If a larger battery is integrated into the headlamp, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The battery system is segmented into a permanent battery unit and a separate booster unit. This segmentation simplifies the main headlamp design while providing extended battery life through the add-on booster, avoiding the complexity of designing a large integrated battery system.
Solution Approach 2:
The booster unit acts as an intermediary component that connects to the battery unit to provide additional power. This intermediary approach extends battery life without requiring the main headlamp to contain a large complex battery system, maintaining simplicity in the core device.
3Weight of moving object
If the battery unit is positioned at the back of the head, then the weight distribution is improved, but the ease of operation is reduced
Solution Approach 1:
The battery system is segmented into two units positioned at different locations on the head. The primary battery unit is positioned at the back for balanced weight distribution, while the booster unit can be positioned more forward for easier access and operation when needed.
Solution Approach 2:
The removable booster unit serves as an intermediary that bridges the gap between optimal weight distribution (back position) and ease of operation (front access). Users can attach the booster when operation is needed and detach when not needed, balancing both requirements.

AI summary
Various embodiments herein provide a headlamp with a light unit, a battery unit, and a booster unit. The booster unit includes an engagement mechanism (e.g., a bar, such as a U-shaped bar) that mechanically couples the booster unit to the battery unit to provide additional power. The engagement mechanism may further form a clip to couple the booster unit to another item when the booster unit is not coupled to the battery unit. The booster unit may include one or more lights, one or more controls for the one or more lights, and/or an outgoing power port to provide power to another device (other than the battery unit and light unit). Other embodiments may be described and claimed.
