Optical Lens Suspension Grip for Scratch-Free Handling and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass holder devices for optical lenses are prone to scratching and fingerprint contamination during handling, have a bulky design, and are not adaptable to varying lens sizes, especially thick or thin ones, and do not allow for efficient storage or easy disassembly.
Innovation Solution
A universal glass holder device with cylindrical bars and removable grips featuring a U-shaped hook for secure suspension, a V-shaped clutching mechanism to grip lenses without direct contact, and a stop to prevent rotation, enabling easy assembly and disassembly while maintaining lens position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass holder grips are made monolithic and securely welded to the bar, then the lenses are held securely during treatment and transportation, but the device occupies significant storage volume and cannot be easily disassembled
Solution Approach 1:
The glass holder grip is divided into separate components: a center rod that can be suspended from the bar, lens holders that attach to the center rod, and lenses. This segmentation allows the device to be disassembled for compact storage while maintaining secure holding during operation. The center rod includes a suspension element that engages with the bar, enabling easy assembly and disassembly without welding.
Solution Approach 2:
The device transitions from a static welded structure to a dynamic, reconfigurable system. The suspension element allows the center rod to be attached or detached from the bar as needed. The lens holders can be positioned at different locations on the center rod to accommodate varying lens sizes and treatment requirements, providing adaptability while reducing storage volume.
2Device complexity
If the glass holder device is designed with fixed configuration, then the structure is simple and robust, but it cannot accommodate optical glass of varied sizes and thicknesses
Solution Approach 1:
The glass holder device is designed as a universal system that can accommodate optical glass of various sizes, thicknesses, and shapes. The center rod serves multiple functions: suspension from the bar, support for lens holders, and positioning reference. The lens holders can be adjusted or repositioned to accommodate different lens dimensions, making the device versatile without requiring completely different structures for each lens type.
Solution Approach 2:
The device incorporates adjustable and reconfigurable elements that allow adaptation to different lens specifications. The lens holders can be positioned at different heights and locations on the center rod, and the suspension element allows for flexible installation and removal. This dynamic capability enables a single device structure to handle varied lens sizes and thicknesses effectively.
3Ease of operation
If lenses are handled directly with fingers for control operations, then the operation is simple and quick, but the glasses are scratched or contaminated with finger prints
Solution Approach 1:
The glass holder device serves as an intermediary between the operator and the optical lenses. Instead of handling lenses directly with fingers, the operator manipulates the lens holders and center rod to position, transport, and secure the lenses. This intermediary mechanism eliminates direct finger contact, preventing scratching and fingerprint contamination while maintaining ease of operation through intuitive mechanical controls.

AI summary
A glass holder device for treatment of optical glasses (4, 4′) or other substrates horizontally supports an elongated bar (1) with evenly spaced notches (10) on a frame and suspends glass holder grips (2) in parallel side-by-side vertical relation. The glass holder grip (2) comprises an axially elongated rod (20), that forms the body of the grip, and holding means (3, 31, 31′) connected to the grip body (20) for clutching the outer periphery (40, 40′) of the optical glass (4, 4′) and holding the glass generally parallel with the lower end portion of and adjacent to a stop (36) bent outwardly from the body (20) for supporting the glass. The upper end portion of the rod (20) includes hanging means (21, 22, 25) for removably connecting the grip to the bar (1) and locking means (11, 23, 12, 25) for preventing free rotation of the grip (2) around the bar (1).
