Punching Shield Angled Surface Indents Anatomical Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional punching shields and bags with cylindrical or square shapes lack anatomical friendliness, limiting the ability to strike flush surfaces and increasing the risk of injury during use.
Innovation Solution
A punching shield with an outer casing featuring a front and rear surface, an angled surface connecting them, radially disposed protrusions, and indents between these, providing multiple striking angles and a padded interior for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylindrical or square shape is used for the punching shield, then the structure is simple and easy to manufacture, but the striking surface cannot properly act as an anatomical friendly surface, limiting the hand's capability to strike flush surfaces
Solution Approach 1:
The outer casing is segmented into multiple flat panels (front panel, rear panel, side panels) connected by edges, rather than using a single cylindrical or square shell. This segmentation allows each panel to be struck independently and provides multiple flat striking surfaces that conform to anatomical hand positions, resolving the contradiction between structural simplicity and anatomical friendliness.
Solution Approach 2:
The invention transitions from a two-dimensional cylindrical or square surface to a three-dimensional multi-panel structure with edges and angles. This dimensional change creates multiple striking surfaces at different orientations, enabling the hand to strike flush surfaces from various angles while maintaining structural manufacturability through modular panel construction.
2Reliability
If a cylindrical shape is used for the punching shield, then the manufacturing process is simple, but the hand's capability to strike flush surfaces is limited, increasing the risk of injury
Solution Approach 1:
The outer casing is divided into multiple detachable panels that can be manufactured separately using standard fabrication processes, then assembled together. This segmentation maintains ease of manufacture while creating multiple flat striking surfaces that reduce injury risk by providing anatomically friendly contact points for the hand during striking motions.
Solution Approach 2:
Different regions of the outer casing are designed with different properties - the panels are made flat and rigid for structural integrity and manufacturing ease, while the edges and angles are designed to create specific striking surfaces that conform to hand anatomy. This local differentiation resolves the contradiction between ease of manufacture and injury reduction.

AI summary
A punching shield is provided. The punching shield includes an outer casing and a padding disposed within the outer casing. The outer casing includes a front surface (striking surface), a rear surface opposite the front surface, and an angled surface running from an outer edge of the front surface to an outer edge of the rear surface. A plurality of protrusions extend from the angled surface and are radially disposed from the outer edge of the rear surface to the outer edge of the front surface. An indent is formed between a pair of protrusions, thereby forming a plurality of indents on the angled surface.
