Nail Blocking Member Guiding Block Formation Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail blocking members in nail guns often fail to consistently bend nails into a desired J shape due to random radial firing directions, leading to incomplete board combinations and potential injuries from protruding nails.
Innovation Solution
A nail blocking member with a guiding block and formation groove that guides the nail to move along a concave groove, utilizing an inclined guiding face and transition face to ensure the nail is bent into a J shape, independent of the firing direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plane shaped nail blocking member is used, then the structure is simple, but the nail cannot be consistently bent into the desired J shape due to random radial firing directions
Solution Approach 1:
The invention replaces the conventional plane shaped blocking member with a circular shaped blocking member that has a curved guiding surface. This curved surface guides the nail along a predetermined path during bending, ensuring consistent J-shape formation regardless of the random radial firing direction. The circular geometry with its continuous curved surface provides reliable nail guidance and bending control.
2Ease of manufacture
If a plane shaped nail blocking member is used, then the manufacturing is easy, but the nail may be bent into incorrect shape causing boards to be unusable
Solution Approach 1:
The circular blocking member with curved guiding surface provides reliable and consistent nail bending guidance. The curved geometry naturally guides the nail along the desired path, ensuring accurate J-shape formation and preventing incorrect bending that would render boards unusable.
Solution Approach 2:
The curved guiding surface acts as an intermediary between the firing portion and the final nail shape. It mediates the interaction by providing a predetermined bending path that ensures consistent J-shape formation, thereby improving reliability while maintaining ease of manufacture.
3Adaptability or versatility
If random radial firing direction occurs, then the nail gun operation is flexible, but the nail bending orientation does not conform to desired direction
Solution Approach 1:
The circular blocking member with its curved guiding surface is specifically designed to accommodate random radial firing directions. The curved geometry provides a predetermined bending path that guides the nail into the correct J-shape orientation regardless of the firing direction, thus maintaining firing flexibility while ensuring bending precision.
Solution Approach 2:
The circular blocking member serves multiple functions: it guides nails from various radial directions, provides a predetermined bending path, and ensures consistent J-shape formation. This universal design accommodates different firing directions while maintaining accurate bending orientation.

AI summary
A nail blocking member for a nail gun. The nail gun includes a firing portion for firing a nail. When an object is pressed upon the nail blocking member by the firing portion, the nail is fired by the firing portion to enter the object. The nail blocking member includes a main body having a contact face, with a formation groove concavely disposed on the contact face, and a guiding block protruding from the formation groove. An object is pressed upon the contact face by the firing portion, and a nail is fired by the firing portion to enter the object to hit the guiding block, such that the nail is guided by the guiding block to move toward the formation groove, so as to be bent along the formation groove and reversely folded back into the object.
