Stapler Nail Guiding Plate Biasing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing staplers with nail guiding mechanisms often cause nails to become stuck due to the distal end being inclined towards the cartridge, and require adjustments for different nail dimensions, leading to potential misalignment and ineffective striking.
Innovation Solution
A stapler with a nail guiding mechanism featuring a guiding plate and biasing mechanism, where the guiding plate is biased towards the cartridge by elastic members to prevent nail sticking and includes supporting assemblies for centralizing nails of various dimensions, ensuring proper alignment and striking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guiding feet are inclined toward the nail outlet when centralizing the nail, then the nail can be centralized, but the distal end of the nail tends to incline toward the cartridge and gets stuck easily
Solution Approach 1:
Instead of inclining the guiding feet toward the nail outlet (which causes the distal end to incline toward the cartridge), the patent inverts the approach by using a guiding plate with a guiding surface that is inclined away from the nail outlet. This causes the nail distal end to incline away from the cartridge, preventing it from getting stuck while still achieving centralization.
2Adaptability or versatility
If a pressing board is provided to control the gap size for different nail dimensions, then the stapler can accommodate different nail dimensions, but the controlling member needs to be adjusted and users may forget to adjust it, causing two nails to be struck at the same time
Solution Approach 1:
The patent eliminates the need for user adjustment by providing a guiding plate that automatically adapts to different nail dimensions. The guiding plate's inclined surface and positioning structure self-adjust to accommodate various nail sizes without requiring user intervention, thus preventing the error of striking two nails simultaneously while maintaining versatility.
3Reliability
If the guiding plate is biased toward the cartridge, then the nail is prevented from sticking to the cartridge, but the guiding plate must be positioned precisely to maintain proper nail alignment
Solution Approach 1:
The patent uses a biasing mechanism (such as a spring) to dynamically position the guiding plate. The guiding plate is biased toward the cartridge, but this dynamic positioning allows the guiding plate to maintain precise alignment with the nail while preventing the nail from sticking to the cartridge. The elastic biasing force ensures consistent positioning without requiring rigid fixed mounting.
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 solution effectively prevents nail sticking and allows for the use of different nail dimensions by ensuring the nail is biased away from the cartridge during striking, maintaining proper alignment and enhancing the striking effect without the need for frequent adjustments.
Implementation Method 1
a biasing mechanism disposed between the main body and the guiding plate, the biasing mechanism including a plurality of elastic members, each said elastic member having one end connected to the guiding plate and the other end connected to the main body, said elastic members abutting against the guiding plate and normally biasing the upper end toward the cartridge
