Pincer Paddle with Movable Extension for Grip Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Table tennis players using the penhold grip face difficulties in executing top-spin shots, especially backhand shots, due to the handle's restriction on blade movement, whereas shakehanders excel in backhand top-spin but struggle with spin control on forehand shots, and both grips are challenging for beginners to master.
Innovation Solution
The Pincer Paddle design features a handle angled to the blade, allowing it to follow the forearm's line, enabling RPB and RPF shots, and includes adjustable thumb and forefinger grips for intuitive spin control, allowing players to choose rubber surfaces for optimal shots and switch between grip styles during play.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If penhold grip is used, then spin control is improved, but backhand top-spin capability deteriorates
Solution Approach 1:
The paddle introduces a movable extension that can shift position along the blade tail, allowing the playing surface to dynamically adjust its relationship with the handle. This enables the blade to follow the forearm line during backhand shots while maintaining the penhold grip's spin control advantages through wrist movement.
Solution Approach 2:
The invention adds a longitudinal dimension to the traditional penhold grip by extending the blade tail with a movable section. This extra dimension allows the playing surface to be positioned optimally for both forehand and backhand shots, resolving the spatial conflict between grip style and shot type.
2Adaptability or versatility
If shakehand grip is used, then backhand top-spin is improved, but forehand spin control deteriorates
Solution Approach 1:
The movable extension allows players to dynamically reposition the playing surface relative to the handle, enabling optimal wrist angles for forehand spin shots while maintaining shakehand grip's backhand capabilities. The extension moves to accommodate different shot requirements.
3Device complexity
If traditional paddle design is used, then structural simplicity is improved, but ease of operation for multiple shot types deteriorates
Solution Approach 1:
The paddle blade is segmented into a fixed portion and a movable extension portion. This segmentation allows the extension to move independently to optimal positions for different shots, while the main blade structure remains simple and traditional.
Solution Approach 2:
The movable extension acts as an intermediary element between the handle and the main blade playing surface. It mediates the conflict between handle position and optimal blade orientation, allowing both forehand and backhand shots to be executed effectively.

AI summary
The “Pincer Paddle” is a novel racquet for use in any suitable sport but especially for table tennis. It allows a player to hit the ball with both the front and back sides of the paddle blade on the both the forehand and backhand, when driving, pushing or smashing. Since a player is allowed to use different rubbers on the front and back of the paddle this can make it easier to add spin to the ball or handle the spin put on the ball by the other player depending on which rubber is selected. The ergonomic design allows a player to make these shots over a greater range of angles even when reaching or when close to the body.
