Elastic Adjusting Portion Nail Gun Single-Fire Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail guns require frequent adjustments to accommodate different types and thicknesses of nails, leading to inconvenience and potential simultaneous firing of multiple nails.
Innovation Solution
A nail gun design featuring a main body with a pressing element, outer housing, punching board, detent portion, and an adjusting portion with an elastic member, which uses elastic force to prevent multiple nails from entering the nail slot, ensuring each nail is fired individually and accommodating various nail shapes and thicknesses without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a nail gun uses a fixed platen position to accommodate different nail thicknesses, then the nail gun can handle various nail types, but multiple nails may be pushed simultaneously causing simultaneous firing
Solution Approach 1:
The platen is made movable rather than fixed, allowing it to adjust its position dynamically based on nail thickness. The platen can move forward to accommodate thicker nails and retract for thinner nails, solving both the adaptability issue and the simultaneous firing problem through dynamic positioning control
Solution Approach 2:
The system uses a sensor to detect the presence and thickness of nails, providing feedback that controls the platen's position. This feedback mechanism ensures the platen is positioned correctly for each nail type, preventing multiple nails from being pushed simultaneously while maintaining versatility
2Reliability
If a controlling member is added to adjust the platen position, then single nail firing can be controlled, but the device complexity increases and requires constant manual adjustment
Solution Approach 1:
The system automatically adjusts the platen position based on sensor feedback without requiring manual intervention. The controlling member is integrated into the automated control system, eliminating the need for users to constantly adjust it manually while maintaining reliable single nail firing control
Solution Approach 2:
The manual mechanical adjustment system is replaced with an automated control system that uses sensors and actuators. This substitution reduces device complexity from the user perspective while maintaining precise control over platen position for reliable single nail firing
3Adaptability or versatility
If the nail slot size is fixed, then the structure is simple, but thicker nails cannot be accommodated properly
Solution Approach 1:
The nail slot structure incorporates movable components that can dynamically adjust their position to accommodate different nail thicknesses. This dynamic adjustment allows thicker nails to be properly accommodated without significantly increasing overall device complexity
Solution Approach 2:
The nail slot structure is designed with multi-functional elements that serve both as guides and adjustable positioning mechanisms. This universal design allows the same structure to handle various nail types while minimizing the increase in device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nail gun ensures convenient and safe operation by preventing simultaneous firing of multiple nails, accommodating different nail types and thicknesses without user intervention, and providing sufficient space for thicker nails to be shot smoothly.
Implementation Method 1
the adjusting portion presses the elastic member to be transformed when the nail abuts the adjusting portion. At the present time, an elastic force of the elastic member would still let the adjusting portion has enough power to prevent another nail adjacent to the nail from moving toward the nail slot continuously

AI summary
A nail gun of the present invention includes an adjusting portion which has elasticity. The elasticity of the adjusting portion is able to offset a thrust force of a nail pusher pushed by a magazine, so that a nail slot receives a nail only. The nail gun ensures not to shoot two sticks of nails simultaneously. The nail squeezes one side of the adjusting portion in a firing process so that the nail gun can provide sufficient space. Thereby when the nail is thicker, it can be shot by the nail gun. The present invention need not adjust by hand anymore for shooting different thickness of nails. The nail gun can not shoot two sticks of nails simultaneously.
