Self-Tapping Rivet Installation Tool With Manual Drill-Rivet Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional riveting tools require an air compressor and are not suitable for outdoor or DIY applications, and they necessitate pre-drilling holes, leading to cumbersome operations.
Innovation Solution
An installation tool for self-tapping rivet fasteners that integrates a body, movable sleeve, handle, single-direction thrust bearing, switcher, drive rod, transmission shaft, locking element, and screw nut, enabling both drilling and riveting without external power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional pneumatic or electric riveting tool is used, then the riveting function is achieved, but the requirement for air compressor or external power source makes it unsuitable for outdoor or DIY applications
Solution Approach 1:
The patent extracts and removes the dependency on external power sources (air compressors or electric motors) from the riveting system. The manual operation mechanism directly transforms user input force into drilling and riveting actions, eliminating the need for complex power supply systems and making the tool suitable for outdoor and DIY applications.
Solution Approach 2:
The tool is designed to be self-powered through manual operation. The user's direct mechanical input through the handle and movable sleeve simultaneously drives both the drilling function (via the switcher and transmission shaft) and the riveting function (via the drive rod and locking element), making the system self-sufficient without external power sources.
2Productivity
If a conventional riveting tool is used, then the riveting function is achieved, but pre-drilling holes is required which causes troublesome operation
Solution Approach 1:
The patent merges the drilling function and riveting function into a single integrated tool and a single continuous operation. The movable sleeve's movement simultaneously engages both the switcher (for drilling) and the drive rod (for riveting), allowing the user to complete both operations in one action sequence without separate drilling and riveting steps.
Solution Approach 2:
The tool is designed with multi-functionality, where the same manual input mechanism serves dual purposes: driving the transmission shaft for drilling through the switcher, and driving the locking element for riveting through the drive rod. This universal design eliminates the need for separate specialized tools for drilling and riveting.
3Ease of operation
If a manual riveting tool is used, then the operation is simple, but the central rod is pulled toward the user which reduces operational safety
Solution Approach 1:
The patent inverts the direction of the riveting action. Instead of pulling the central rod toward the user (as in conventional manual tools), the locking element and drive rod are designed to push or draw the fastener away from the user's hand position. The movable sleeve moves away from the user to drive the riveting action, reversing the harmful motion direction and improving safety.
