Sheet Metal Working Tool Opener for Collapsed Pittsburgh Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet metal working tools face challenges in efficiently opening and reforming Pittsburgh locks, particularly when the pocket collapses during the bending process, and in inserting flanged edges through insulation-covered sections.
Innovation Solution
A tool with a shaft, a striking tool, and an opener is designed, where the opener includes a flat plate and a C-shaped structure attached to the shaft, allowing for the application of force to pivot the shaft and use the striking tool to insert edges into pockets, even through insulation, facilitating the opening and completion of Pittsburgh locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional sheet metal working tool is used to open collapsed pockets and insert flanged edges, then the tool structure remains simple, but the tool cannot effectively penetrate insulation-covered sections and the operation becomes difficult
Solution Approach 1:
The patent combines multiple functional components into a single integrated tool: a shaft with a striking tool at one end and an opener with C-shaped structure at the other end. This merging allows the tool to perform both striking operations and pocket-opening operations through insulation in one unified device, resolving the contradiction between operational effectiveness and structural simplicity.
Solution Approach 2:
The opener is segmented into a flat plate and a C-shaped structure with spaced ends, creating a functional division that allows the tool to effectively engage with and manipulate sheet metal edges through insulation. The C-shaped structure's opening allows it to accommodate and maneuver around the flanged edges being inserted.
2Reliability
If existing tools are used to work with Pittsburgh locks, then the manufacturing process remains simple, but the tools cannot effectively open collapsed pockets during the bending process
Solution Approach 1:
The C-shaped opener structure is designed to be inserted into collapsed pockets before the final bending operation. By preliminarily opening the collapsed pocket structure, the tool creates the necessary space and configuration for the subsequent bending and locking operations to proceed reliably.
Solution Approach 2:
The opener acts as an intermediary tool between the worker and the collapsed pocket. The C-shaped structure with its opening allows it to mediate the interaction by physically engaging with the pocket edges and leveraging them open, enabling the worker to indirectly manipulate the difficult-to-reach collapsed structure.
3Productivity
If a single-function tool is used for striking or opening operations, then the tool design remains simple, but separate tools are required for different operations reducing productivity
Solution Approach 1:
The tool is designed with universal functionality to perform multiple operations: the shaft can be used for striking, the striking tool at one end for hammering operations, and the opener with C-shaped structure at the other end for opening pockets and manipulating sheet metal edges. This multi-functionality eliminates the need for multiple separate tools, thereby increasing productivity.

AI summary
A sheet metal working tool has a shaft with a first end and a second end, a striking tool attached to the first end of the shaft, and an opener attached to the second end of the shaft. The opener includes a flat plate with a first end and a second end and a C-shaped structure having a first-end and a second end, the first end of the flat plate and the first end of the C-shaped structure joined together with the second end of the plate spaced from the second end of the C-shaped structure.
