Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reaching and grasping tools have limitations in their gripping heads, which restrict their utility in grasping various items effectively.
Innovation Solution
A reaching and grasping tool with a gripping head that provides multiple gripping states by using jaw members with elastic movement, allowing different types of gripping forces to be applied, and includes features like telescoping and rotation to accommodate various items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional gripping head design is used, then the device structure is simple, but the utility for grasping different items is limited
Solution Approach 1:
The gripping head incorporates movable jaw members that can elastically move relative to each other, transitioning between open and closed positions. This dynamic mechanism allows the gripping head to adapt to different item sizes and shapes, providing multiple gripping states (light, medium, firm grip) without requiring multiple separate tools, thus improving versatility while maintaining reasonable structural complexity
Solution Approach 2:
The gripping head is divided into separate jaw members (first jaw member and second jaw member) that can move independently. This segmentation allows each jaw to conform to the contours of different items, enabling the device to grasp various objects effectively while keeping the overall structure modular and manageable
2Adaptability or versatility
If a single gripping force is applied, then the gripping mechanism is simple, but the ability to grasp different types of items is reduced
Solution Approach 1:
The elastic movement mechanism of the jaw members creates multiple stable gripping states (light grip, medium grip, firm grip) based on the degree of compression applied. This dynamic system allows the user to grasp different item types with appropriate force levels without complex control mechanisms, as the elastic deformation naturally provides force modulation
Solution Approach 2:
The gripping force is controlled by changing the compression parameter of the elastic jaws. As the trigger is pulled, the jaws compress elastically, transitioning through different force states. This parameter-based control (compression distance) simplifies the mechanism while enabling versatile grasping of different item types requiring different force levels
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 can grasp a wider variety of items with improved efficiency due to its ability to adjust gripping force and accommodate different sizes and shapes through multiple gripping states, telescoping, and rotation.
Implementation Method 1
the first-grip member is configured to elastically move with respect to the main and second-grip members in response to a gripping pressure exerted on an item being gripped
