Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tweezers are difficult to operate, especially in complex environments like the oral cavity, ear canal, or intestinal tract, due to reliance on manual control and operator experience.
Innovation Solution
A visual tweezer design featuring a main shell, connecting shank, tweezer assembly, driving assembly, circuit assembly, and camera assembly, with a press member, push member, and connector that allows for precise control through a preset direction, facilitated by elastic members and inclined surfaces for easy opening and closing, and a camera for clear operation visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control method is used for tweezer operation, then device structure remains simple, but ease of operation deteriorates in complex environments
Solution Approach 1:
The patent replaces manual mechanical control with an automated driving assembly that includes a driving member, transmission mechanism, and connecting member. This automated system controls the opening and closing of the tweezer assembly through mechanical transmission, eliminating the need for direct manual manipulation while maintaining structural feasibility.
Solution Approach 2:
The patent introduces a connecting member as an intermediary element that transmits driving force from the driving assembly to the tweezer assembly. This intermediary mechanism enables remote control of the tweezer's opening and closing actions, improving operability in complex environments where direct manual control is difficult.
2Measurement precision
If camera assembly is added for visualization, then measurement precision improves, but device complexity increases
Solution Approach 1:
The camera assembly serves multiple functions: it provides visual feedback for precise operation, documents the procedure, and enables remote monitoring. By integrating this multi-functional component, the patent achieves improved measurement and observation precision while justifying the added complexity through enhanced operational capabilities.
Solution Approach 2:
The camera assembly provides visual feedback to the operator, enabling real-time observation of the tweezer's position and the target object. This feedback mechanism improves measurement precision by allowing the operator to make accurate adjustments based on visual information, thereby justifying the increased device complexity.

AI summary
A visual tweezer includes a main shell, a connecting shank, a tweezer assembly, a driving assembly, a circuit assembly and a camera assembly. The driving assembly including a press member, a push member, and a connector, wherein the push member is arranged on one side of the connecting shank close to the main shell; the connector is connected to the push member and is connected to the tweezer assembly through the second opening and the second storage cavity; the press member is abutted with the push member and is used for driving, when pressed by an external force, the push member to move in the preset direction, so that the connector moves in the preset direction to drive the tweezer assembly to be opened or closed. It can be convenient to control opening and closing of the tweezer, and operations of the user are facilitated.
