Elastic Holder with Concave Restriction for Uniform Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment tools face challenges in uniformly applying pressure to a target region during procedures like coagulation and incision, leading to inconsistent treatment performance due to the lack of effective grasping mechanisms that prevent elastic deformation of holder portions.
Innovation Solution
A treatment tool design featuring a holder portion with a concave structure that is elastically deformed to reduce its depth, mounted on a treatment surface with a restricting mechanism to prevent return to the original shape, enhancing grasping force and uniform pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a conventional holder portion is used without elastic deformation, then the structure is simple and easy to manufacture, but the grasping force is insufficient and pressure application is non-uniform
Solution Approach 1:
The holder portion is designed to be elastically deformable, transitioning from a static structure to a dynamic one that can change shape during operation. The holder portion deforms elastically under compression force to reduce the depth of the concave portion, enabling uniform pressure application and enhanced grasping force while maintaining structural simplicity
Solution Approach 2:
The physical state of the holder portion is changed by applying compression force, causing elastic deformation that reduces the depth of the concave portion. This parameter change (depth reduction) directly increases the grasping force and improves pressure distribution uniformity without adding structural complexity
2Reliability
If the holder portion is allowed to return to its original shape, then the structure maintains its initial configuration, but the grasping force decreases and treatment performance becomes inconsistent
Solution Approach 1:
The restricting portion is pre-installed on the treatment portion before the holder portion returns to its original shape. This preliminary action prevents the holder portion from returning to its initial state, maintaining the elastic deformation and ensuring consistent grasping force and treatment performance throughout the procedure
Solution Approach 2:
The restricting portion acts as an intermediary element between the holder portion and the treatment portion. It mediates the shape change by preventing the holder portion from returning to its original configuration, thereby maintaining the improved grasping force and uniform pressure application without requiring complex locking mechanisms
3Reliability
If multiple separate components are used for grasping and pressure application, then each component can be optimized independently, but the overall device complexity increases
Solution Approach 1:
The holder portion and treatment portion are combined into an integrated structure where the holder portion is mounted on the treatment portion. The restricting portion is also integrated, being arranged between the treatment portion and holder portion. This merging reduces the number of separate components while maintaining uniform pressure application through the elastic deformation mechanism
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 tool achieves stable and uniform pressure on the target region, improving treatment performance by maintaining elastic deformation and reducing the number of components through the use of a rotation shaft or pins as restricting portions.
Implementation Method 1
The holder portion is formed of an elastically deformable material, and includes a first region having a first contact surface in contact with the opposing surface, a second region having a second contact surface in contact with the opposing surface, and a connection region that is arranged between the first contact surface and the second contact surface and that includes a concave portion. The holder portion is mounted on the opposing surface in an elastically deformed state such that the first contact surface and the second contact surface are in contact with the opposing surface and such that a depth of the concave portion is a second depth that is smaller than a first depth of the concave portion in a non-elastically deformed state.
