Translucent Pincer Tips with Planoconvex Lensing for Gemstone Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pincers obstruct the view and block light from reaching small items being grasped, particularly in fields like jewelry and gemology where illumination from multiple angles is crucial for proper viewing.
Innovation Solution
Design of pincers with at least partially translucent grasping faces and convex outer surfaces that transmit light from the outer leg sides to the grasping faces, creating a planoconvex lens effect to enhance illumination and visibility of the item, using materials like glass or optical plastics for the grasping sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional opaque pincers are used to grasp items, then the grasping function is achieved, but the view of the item is obstructed and light is blocked from reaching the item
Solution Approach 1:
The pincer legs are designed with different optical properties in different regions: the grasping faces are made translucent to allow light transmission, while the rest of the leg structure remains opaque for structural integrity and grasping function. This local differentiation of material properties resolves the contradiction by allowing light to reach the item through the grasping faces while maintaining effective grasping capability.
Solution Approach 2:
The translucent grasping faces act as an intermediary between the external light source and the item being grasped. Instead of completely blocking light like conventional opaque pincers, the translucent material allows light to pass through while still providing the necessary mechanical grasping function, thus mediating between the need for grasping and the need for light transmission.
2Reliability
If conventional opaque pincers are used, then the item can be grasped securely, but the item becomes shadowed and darker
Solution Approach 1:
The pincer design applies translucency specifically to the grasping faces where light transmission is needed, while maintaining opacity in other regions for structural strength and secure grasping. This localized application of optical properties allows the item to receive sufficient light while the pincer maintains reliable grasping capability.
Solution Approach 2:
Instead of making the entire pincer translucent which would compromise structural integrity and grasp security, the invention applies translucency partially only to the necessary grasping face regions. This partial translucency provides sufficient light transmission without over-extending the translucent material where it would be structurally inadequate.
3Illumination intensity
If the pincer grasping faces are made translucent, then light can be transmitted to illuminate the item, but the structural strength and grasping capability may be compromised
Solution Approach 1:
The pincer legs are designed with different optical properties in different regions: the grasping faces are made translucent to allow light transmission, while the rest of the leg structure remains opaque for structural integrity and grasping function. This local differentiation of material properties resolves the contradiction by allowing light to reach the item through the grasping faces while maintaining effective grasping capability.
Solution Approach 2:
The pincer employs composite construction combining translucent and opaque materials in a single structure. The translucent material is used specifically for the grasping faces where light transmission is required, while opaque material is used for the leg bodies and other structural components where strength and rigidity are needed, creating a functionally optimized composite structure.
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
The solution allows for improved visibility and brilliance of items like gemstones by allowing light to be focused onto the grasping faces, reducing shadowing and enhancing the appearance of the item being examined.
Implementation Method 1
at least one of the legs 102—and preferably both of the legs 102—is at least partially translucent between its grasping face 112 and a portion of the outer leg side 106 opposite the grasping face 112, whereby light incident on this portion is transmitted through the leg 102 toward the grasping face 112
Implementation Method 2
the portion of the outer leg side 106 opposite the leg's grasping face 112 defines an at least partially convex outer surface 114, whereby light incident on this convex outer surface 114 is transmitted through the leg 102 and is at least partially focused toward the grasping face 112
Implementation Method 3
the leg's grasping face 112 is preferably at least substantially planar, with the grasping face 112 and convex outer surface 114 of the leg 102 effectively defining a planoconvex lens to better focus light towards a grasped item

AI summary
A pincer (e.g., a tweezer) has tips which are at least substantially transparent, such that a user can at least partially view an object being grasped through the tips, and/or such that the tips collect and channel incident light onto the grasped item. The tips preferably have an exterior which is convex in one or more dimensions, and are configured and/or coated such that light falling on the tip exteriors is focused onto a spot or band on the item. Since the tips can enhance illumination of an item being grasped, they can particularly enhance the viewing of translucent materials such as gemstones or selected biological materials.
