One-Handed Ratcheting Handle with Integrated Push Button Controls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ratcheting handles require users to stabilize the handle with one hand and operate the mechanism with the other, making it inconvenient for tasks like surgical procedures where one-handed operation is necessary.
Innovation Solution
A handle device with an internally disposed ratcheting mechanism and conveniently located push buttons allows for selection and operation of the mechanism using only one hand, enabling both mode selection and handle securing with the same hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ratcheting handles use separate hands for handle stabilization and mechanism operation, then the ratcheting mechanism can be reliably controlled, but the device requires two hands for operation reducing efficiency in one-handed applications
Solution Approach 1:
The patent combines the handle stabilization function and the ratcheting mechanism operation function into a single hand operation. The push button controls are positioned on the handle body such that the user can simultaneously grasp the handle and actuate the ratcheting mechanism with one hand, merging two previously separate functions into a unified one-handed operation.
Solution Approach 2:
The patent repositions the ratcheting mechanism controls from a separate location requiring two-handed operation to an integrated position on the handle body itself. This spatial reconfiguration allows the controls to be accessed in the same dimensional space as the handle grip, enabling one-handed operation through three-dimensional integration of controls and grip area.
2Productivity
If conventional ratcheting handles require two hands for operation, then precise control of the ratcheting mechanism is achieved, but productivity decreases in procedures requiring one-handed operation
Solution Approach 1:
The patent merges the handle grip function and the ratcheting control function into a single operable unit that can be controlled by one hand. The push button controls are integrated into the handle body at positions accessible during single-handed grasping, allowing simultaneous execution of both functions and thereby improving productivity in one-handed applications.
3Reliability
If conventional ratcheting handles use lever or pivotal actuation mechanisms, then the ratcheting function is reliable, but the device complexity and difficulty of one-handed operation increase
Solution Approach 1:
The patent extracts the essential control function from complex lever or pivotal actuation mechanisms and implements it through simpler push button controls. The push buttons directly actuate the ratcheting mechanism without requiring intermediate lever systems or pivotal movements, thereby maintaining reliability while reducing structural complexity and facilitating one-handed operation.
Solution Approach 2:
The patent replaces traditional mechanical lever or pivotal actuation systems with a simplified push button control mechanism. This substitution maintains the reliable ratcheting function while eliminating the complexity of multi-component mechanical linkages, making the device more suitable for one-handed operation.
