Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional striking devices for hammering tests have complex control and device configurations, leading to inaccurate striking of the test object.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional striking device with complex control configuration is used, then the device can perform hammering tests, but the device configuration becomes complicated and cannot accurately strike the striking point
Solution Approach 1:
The striking device is divided into functionally independent modules: a striking unit with striking section, a support unit with base and support section, and a link mechanism with driving link, driven link, and intermediate link. Each module performs a specific function, allowing the overall system to achieve accurate striking without requiring complex integrated control.
Solution Approach 2:
Instead of using complex control systems to adjust the striking position, the invention inverts the approach by designing a mechanical link mechanism where the driving link and driven link rotate about perpendicular rotational shafts. This mechanical arrangement automatically ensures that the striking section moves along a trajectory that passes through the predetermined striking point, eliminating the need for complex control.
2Device complexity
If a manual simple striking device is used, then the device configuration is simple, but the device cannot accurately strike the striking point
Solution Approach 1:
The link mechanism acts as an intermediary between the simple manual operation and the precise striking requirement. The driving link and driven link, connected through the intermediate link, translate simple rotational motion into a precise striking trajectory, ensuring accurate striking without requiring complex control systems.
Solution Approach 2:
The invention introduces a spatial dimension by having the driving link and driven link rotate about perpendicular rotational shafts. This three-dimensional arrangement allows the striking section to follow a specific trajectory that ensures accurate striking, transforming a simple two-dimensional manual operation into a precise three-dimensional striking motion.

AI summary
A striking device includes a striking section that strikes a test object. This striking device is characterized by having: a vertically long intermediate link that is coupled to the striking section and can move in a state of maintaining a vertical orientation; and a laterally long driving link and a driven link that is driven by the driving link, one end of each of the driving link and the driven link being rotatably coupled to the intermediate link, and the driving link and the driven link being parallel to each other, in that the other end side of each of the driving link and the driven link rotates about a rotational shaft that is provided in a perpendicular direction to a vertical line at different positions on the same vertical line.
