LENS DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111119 titled 'LENS DEVICE
Simplified Explanation
The patent application describes a lens device with a braking mechanism that generates a braking force to control the movement of the lens mechanism.
- The lens device includes a lens mechanism, a movement mechanism, and a braking mechanism.
- The braking mechanism consists of a braking member, a support member, and a pressing member.
- The braking member has a pressing surface that presses against a pressing target surface of the movement member.
- The pressing member applies a pressing force to the braking member, creating a contact portion at the periphery of a recess portion.
Potential Applications
This technology could be applied in camera lenses, telescopes, microscopes, and other optical devices where precise control of lens movement is required.
Problems Solved
This technology solves the problem of controlling the movement of a lens mechanism with precision and stability, ensuring accurate focus and image quality.
Benefits
The benefits of this technology include improved accuracy in lens movement, reduced vibration and shaking, and enhanced overall performance of optical devices.
Potential Commercial Applications
Potential commercial applications of this technology include professional photography equipment, medical imaging devices, surveillance systems, and scientific instruments.
Possible Prior Art
One possible prior art for this technology could be similar braking mechanisms used in other mechanical devices to control movement and prevent sudden stops or jerky motions.
Unanswered Questions
How does this technology compare to existing lens braking mechanisms on the market?
This article does not provide a direct comparison with existing lens braking mechanisms, so it is unclear how this technology differs in terms of performance, cost, or other factors.
What are the specific materials used in the construction of the braking mechanism?
The article does not specify the materials used in the construction of the braking mechanism, leaving a gap in understanding the durability and longevity of the technology.
Original Abstract Submitted
a lens device includes a lens mechanism, a movement mechanism that includes a movement member moving the lens mechanism, and a braking mechanism that generates a braking force with respect to movement of the movement member. the braking mechanism includes a braking member that includes a pressing surface pressing a pressing target surface of the movement member, a support member that supports the braking member, and a pressing member that includes a pressing portion applying a pressing force to a first surface of the braking member. a contact portion between the pressing portion and the first surface is formed at a periphery of a recess portion.
