Innovation Solution
A headlamp system with a base unit and interchangeable beam-forming units, including wide-field, intermediate, and high-intensity options, attached via a threaded connection, allowing for adjustable spot sizes and intensities while maintaining a consistent color temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different head-mounted units are purchased for different spot sizes and light intensities, then the required lighting performance for various procedures is achieved, but the overall cost increases and flexibility is reduced
Solution Approach 1:
The patent implements a universal base unit that can accommodate multiple beam-forming units with different optical characteristics. The base unit includes a standardized mounting interface that accepts various beam-forming units, allowing a single head-mounted platform to perform multiple lighting functions (wide-angle illumination, focused high-intensity beams, intermediate spot sizes) by simply changing the attached beam-forming unit, thereby eliminating the need to purchase separate head-mounted units for different procedures
Solution Approach 2:
The lighting system is divided into two independent segments: a reusable base unit containing the light source and mounting mechanism, and interchangeable beam-forming units that determine the specific lighting characteristics. This segmentation allows the user to retain the base unit and only replace the beam-forming unit when different spot sizes or intensities are needed, reducing overall cost while maintaining versatility
2Adaptability or versatility
If multiple separate head-mounted units are purchased for different procedures, then the required lighting performance is achieved, but the device complexity and number of components increases
Solution Approach 1:
The base unit is designed as a universal platform with a standardized interface that can accommodate multiple types of beam-forming units. This universality allows a single base unit to replace multiple specialized head-mounted units, reducing the total number of devices needed while expanding the range of achievable lighting performance through the interchangeable beam-forming units
3Quantity of substance
If a single head-mounted unit is used for all procedures, then cost is reduced, but the ability to provide optimal spot size and intensity for different procedures is limited
Solution Approach 1:
The system transforms a static, fixed-configuration head-mounted unit into a dynamic, adjustable system. The user can change the beam-forming unit attached to the base unit depending on the procedural requirements, allowing the spot size and light intensity to be dynamically adjusted to match different surgical or dental tasks, thereby achieving optimal lighting performance across various procedures with a single platform
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables versatile lighting solutions by allowing users to switch between different spot sizes and intensities without the need for multiple units, enhancing procedural visibility and reducing costs through a single, adaptable light source.
Implementation Method 1
interchangeable beam-forming units, each separately attachable to the distal opening of the base unit to produce a different light spot size at a given distance
Data Source
AI summary
A head-mounted light source particularly suited to medical and dental applications includes a base unit with a source of illumination directed through a distal opening in the base unit, and a plurality of interchangeable beam-forming units, each separately attachable to the distal opening of the base unit to produce a different light spot size at a given distance. The preferred embodiment includes a wide-field beam-forming unit, an intermediate beam-forming unit and a high-intensity beam-forming unit, such that the diameter of the spot size progressively decreases from the wide-field to the intermediate to the high-intensity unit. The interchangeable beam-forming units are attached to the base unit through a threaded connection. Each interchangeable beam-forming unit may itself include a distal threaded connection for attachment of a UV or other filter. In the preferred embodiment, the base unit includes a clip adapted for attachment to an ocular mounting assembly.
