Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical headlight systems are cumbersome due to battery packs and power cords, which are uncomfortable to wear and can interfere with medical professionals' movements, necessitating a cordless illumination solution.
Innovation Solution
A cordless headlight system featuring a rechargeable battery pod connected to a printed circuit board via mechanical or electrical means, allowing for remote activation and adjustment, and a T-mount connection for secure mounting on a headset or frame, with optional smart charging cradles for continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a battery pack with power cord is used to power the headlight, then continuous operation is achieved, but user mobility and comfort are reduced due to cord interference
Solution Approach 1:
The system divides the power supply into modular battery pods that can be independently attached or removed from the headlight assembly. This segmentation allows the battery to be separated from the main unit, enabling cordless operation while maintaining the ability to quickly swap batteries for continuous operation.
Solution Approach 2:
The patent employs rapid-charging technology that changes the charging parameter from slow traditional charging to fast charging, reducing recharge time to approximately 15 minutes. This parameter change enables continuous operation without requiring a power cord during use.
2Illumination intensity
If a battery pack is mounted on the user to power the headlight, then illumination is provided, but comfort is reduced due to weight and bulk
Solution Approach 1:
The battery system is segmented into compact, lightweight pods that attach directly to the headlight assembly rather than being mounted on the user's body. This eliminates the need for cumbersome head or chest mounts while maintaining sufficient illumination.
Solution Approach 2:
The power source is extracted from the traditional head-mounted battery pack configuration and repositioned as a removable pod that attaches to the headlight assembly itself, eliminating the need for body-mounted battery packs and improving user comfort.
3Duration of action of stationary object
If a power cord is used to supply electrical energy to the headlight, then continuous operation is ensured, but the system becomes cumbersome and interferes with movement
Solution Approach 1:
The power cord is completely extracted from the system, replacing it with a cordless battery pod architecture. This simplifies the system by removing the cord and associated connection management while enabling continuous operation through rapid battery swapping and charging.
Solution Approach 2:
The system incorporates preliminary charging actions through rapid-charging capability, where batteries can be quickly recharged during brief intervals between procedures, ensuring continuous operation without requiring a power cord during actual use.
