Bearing Fitting Tool Hand Guard With Impact-Damping Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using a bearing fitting tool, there is a risk of injury from the hammer striking the user's hand if they miss the intended striking element, as there is no protection to deflect the force away from the hand.
Innovation Solution
A hand guard comprising a plate and a damping connector is integrated into the bearing fitting tool, where the plate deflects force away from the user's hand and the damping connector reduces impact forces, enhancing user safety by absorbing and distributing the impact.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a bearing fitting tool is used without a hand guard, then the tool structure is simple and easy to manufacture, but the user's hand is at risk of injury from missed hammer strikes
Solution Approach 1:
A hand guard is introduced as an intermediary protective element between the user's hand and the bearing fitting tool. The hand guard includes a plate member positioned to deflect missed hammer strikes away from the hand, and a damping element that absorbs impact forces, thereby mediating the harmful interaction between the hammer and the user's hand.
Solution Approach 2:
The damping element is pre-installed on the bearing fitting tool to provide cushioning protection before any impact occurs. This damping element is specifically designed to absorb and reduce impact forces from missed hammer strikes, providing beforehand protection against potential hand injuries without requiring any action from the user at the moment of impact.
2Reliability
If a hand guard with plate and damping connector is added, then user safety is improved by deflecting and dampening impact forces, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The hand guard is segmented into distinct functional components: a plate member for deflecting impact forces and a damping element for absorbing shock. This segmentation allows each component to be manufactured separately using optimal processes (such as injection molding for the plate) and then assembled, improving overall manufacturability while maintaining safety functionality.
Solution Approach 2:
The plate member is designed with specific geometric parameters including a deflection angle and dimensional relationships that optimize its ability to deflect impact forces away from the user's hand. By carefully selecting and optimizing these parameters, the hand guard achieves high reliability in protecting users while maintaining a compact and manufacturable design.
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 hand guard effectively reduces the risk of hand injuries by deflecting the striking force onto the plate, which is reinforced for stability, and the damping connector minimizes the force transmitted to the user's hand, thereby improving safety during bearing fitting operations.
Implementation Method 1
a damping connector configured connect the plate to the fitting tool and to damp impact forces acting on the plate and reduce forces transmitted from the plate to the user's hand
Implementation Method 2
a plate configured to deflect a force acting on the plate away from the hand of a user gripping the fitting tool
