Adjustable Impact Transmission Flank for Parquet Hammer Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hammer arrangements for laying parquet, laminate, or panel boards face issues with adjustable impact transmission flanks that can lead to breakage when dealing with boards of varying material thicknesses, as the impact transmission flank may either not engage effectively or risk attacking the spring.
Innovation Solution
The support flank is made position-adjustable, allowing the height of the impact transmission flank to be adjusted to match the material thickness of the boards, ensuring it engages at a maximum distance from the support flank and preventing contact with the spring, while forming a wedge-shaped gap for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the impact transmission flank is made adjustable to adapt to different board thicknesses, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The impact transmission flank is made dynamically adjustable through a support body that can be positioned at different heights relative to the impact transmission element. This allows the tool to adapt to various board thicknesses while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The position of the support body is changed as a parameter to adapt the impact transmission flank height to different material thicknesses. By adjusting this single parameter, the tool achieves versatility without requiring complete structural redesign, thus balancing adaptability with simplicity.
2Manufacturing precision
If the impact transmission flank is positioned closer to the spring for thinner boards, then the manufacturing precision is improved, but the reliability deteriorates due to risk of spring breakage
Solution Approach 1:
The support body position is dynamically adjusted based on board thickness, allowing the impact transmission flank to be positioned optimally for each material thickness. This dynamic adjustment ensures precise impact transmission while maintaining safe distance from the spring, simultaneously achieving manufacturing precision and reliability.
Solution Approach 2:
The support body is pre-positioned at appropriate distances from the impact transmission element before use, ensuring that the impact transmission flank will not contact the spring even when working with thinner boards. This preliminary positioning prevents potential damage while maintaining effective impact transmission.
3Reliability
If the impact transmission flank is positioned farther from the support flank for thicker boards, then the reliability is improved by avoiding spring contact, but the manufacturing precision worsens due to reduced engagement effectiveness
Solution Approach 1:
The support body position is adjusted dynamically according to board thickness, allowing the impact transmission flank to achieve optimal engagement distance for each material thickness. This ensures reliable operation with thicker boards while maintaining sufficient engagement precision, resolving the contradiction between reliability and manufacturing precision.

AI summary
The invention relates to a hammer assembly with a striking mass (2) that is displaceable along a guide (1) in a striking direction (S) on an anvil (3) and a striking transmission element (4), which has a striking transmission flank (5) extending in the striking direction (S) and having an edge edge (5') for bearing against a striking side (32) of a workpiece (30) and a bearing flank (7) for bearing on a support side (33) of the workpiece (30). Crucially, the distance (H1, H2, H3) of the edge edge (5') of the striking transmission flank (5) from the bearing flank (7) is adjustable, wherein the bearing flank (7) is formed by a support body (6) which is connected to the striking transmission element (4) in a positionally adjustable manner in an adjustment direction (V).
