Tamper With Parallel Grip Members For Precise Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tampers lack ergonomic design and effective control mechanisms, leading to potential injuries and inefficient operation due to the risk of striking legs or feet with the heavy head and inadequate precision in leveling and compacting surfaces.
Innovation Solution
A tamper tool with a shaft, handle, and working head featuring parallel grip members that allow users to center themselves above the work surface, with legs spread shoulder-width apart, hands level perpendicular to the shaft, enabling precise control and balanced weight distribution for efficient compacting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a heavy tamper head is used for effective compaction, then compaction efficiency is improved, but the risk of striking legs or feet increases causing injury
Solution Approach 1:
The patent introduces a new spatial dimension for hand placement by extending grip members laterally from the shaft rather than positioning them vertically or horizontally in traditional locations. This lateral extension allows users to grasp the tool from the sides, creating a stable triangular support structure with the shaft that prevents the heavy head from swinging toward the user's legs or feet.
2Device complexity
If traditional handle design is used, then device simplicity is maintained, but user control precision and safety are reduced
Solution Approach 1:
The handle is segmented into a shaft and separate grip members that extend laterally from the shaft. This segmentation allows the grip members to be positioned optimally for user hand placement while maintaining a simple overall structure. The grip members can be grasped independently, providing precise control without requiring a complex multi-component handle assembly.

AI summary
A tool, such as an impact tool, comprising at least a first and a second grip members extending generally parallel to the shaft on each side of the shaft and configured such that each one of the first and the second grip members is grasped by a user with a respective hand of the user, thereby centering the user above a ground surface to be worked with the tool, with the user's legs spreading about shoulder width, the user's head centered between the user's feet, both the user's hands level on a line generally perpendicular to the shaft, and allowing the user to precisely control the working head.
