Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional staple feeding devices require both hands to operate and are not easily actuated, limiting user convenience.
Innovation Solution
A staple advance device with a receptacle, barrel, mandrel, spring biasing member, guide plate, actuating lever, and guide device that allows for one-handed operation by using a guide pathway and spring biasing elements to facilitate the feeding and driving of collated fasteners with a power driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional staple feeding devices are designed with traditional feeding mechanisms, then they can drive collated fasteners, but they require both hands to operate and are not easily actuated
Solution Approach 1:
The patent applies dynamics by making the guide plate movable rather than fixed. The guide plate can shift between different positions to accommodate different fastener types and sizes, allowing the device to adapt dynamically to various operating conditions. This mobility enables one-handed operation while maintaining the capability to drive different collated fasteners.
Solution Approach 2:
The patent changes geometric parameters of the feeding mechanism, specifically the angle and position of the guide plate relative to the barrel. By adjusting these parameters, the device can accommodate different fastener dimensions and achieve proper engagement without requiring complex adjustment mechanisms, thus maintaining ease of operation.
2Adaptability or versatility
If the guide pathway is designed with fixed geometry, then the structure is simple, but it cannot accommodate fasteners of different sizes and types
Solution Approach 1:
The guide plate is designed to be movable within the receptacle, allowing it to change position and orientation based on the fastener type being used. This dynamic adjustment capability enables the device to accommodate various fastener sizes and configurations without requiring multiple dedicated guide pathways for each fastener type.
Solution Approach 2:
The single movable guide plate serves multiple functions by being repositionable to accommodate different fastener types. Rather than having separate fixed guide pathways for each fastener size, one universal guide plate can be positioned differently to serve multiple purposes, reducing overall device complexity while increasing adaptability.
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
Enables efficient and single-handed operation of driving collated staples or screws, enhancing user convenience and ease of use.
Implementation Method 1
a spring biasing member engaged in the chamber of the receptacle and engaged with the barrel for biasing and forcing the barrel out of the chamber of the receptacle selectively, and for allowing the barrel to be forced to engage into the chamber of the receptacle selectively
Implementation Method 2
a spring biasing element engaged with the gate for biasing and moving the gate to contact and engage with the tilted surface selectively
