Stapling Device with Openable Shaft Cover for Stuck Staple Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stapling devices, such as those used for fixing heating pipes to insulating substrates, often have staples get caught in the stapling shaft, rendering the device unusable and requiring time-consuming maintenance to rectify.
Innovation Solution
A stapler design featuring a two-part staple shaft with a movable shaft cover and body, where a spring mechanism allows for easy access and maintenance by enabling the staple shaft to be opened, allowing stuck staples to be removed while the same spring controls the staple setting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a single-piece stapling shaft is used, then the structure is simple and reliable, but maintenance and removal of stuck staples become difficult and time-consuming
Solution Approach 1:
The stapling shaft is divided into two separate components: a shaft body and a shaft cover. The shaft cover can be displaced relative to the shaft body to open the staple chute, providing access to the staple shaft for maintenance and removal of stuck staples. This segmentation allows easy maintenance while maintaining structural integrity during operation.
2Ease of operation
If the shaft cover is fixed in position, then the structure is stable and simple, but access to the staple shaft for maintenance is difficult
Solution Approach 1:
The shaft cover is designed to be movable relative to the shaft body through a displacement mechanism. During normal operation, the shaft cover remains in a fixed working position forming a complete stapling shaft. For maintenance, the shaft cover can be displaced to open the staple chute and provide access to the staple shaft, then returns to its working position to restore full functionality.
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 design improves handling and maintenance accessibility, allowing for efficient removal of stuck staples and continued use without external tools, enhancing the device's usability and reliability.
Implementation Method 1
a spring, which is supported at one end on the punch and exerts a force on the shaft cover, which presses the shaft cover against the shaft body

AI summary
The clamping device (100) has a manhole cover (20) that is mounted opposite to a shaft portion (30) which is moved along setting direction. The shaft portion is provided along a shaft bracket (11). A punch (40) is provided opposite to the manhole cover. A plunger (50) is attached at one end of abutment portion (41). The compressive force is exerted on the manhole cover so that shaft portion is pressed against the abutment portion.
