Flat Lever Punch with Nesting Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual punch devices for sheet materials, such as lever and palm punches, are bulky, leading to disorganization and difficulty in storing and identifying multiple shapes.
Innovation Solution
A compact, flat lever punch design with a locking assembly that allows the lever to be positioned parallel to the fissure, enabling efficient storage and easy identification, featuring a pivot coupling, resilient members, and a flattened nose for vertical storage, maintaining a stable and flat profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lever or palm punch devices are used, then the punching function is achieved, but the devices become bulky and difficult to store and organize
Solution Approach 1:
The lever is designed to nest within the punch body when in the closed position, with the lever fitting into a recess or cavity in the punch body. This nesting arrangement allows the punch device to achieve a compact, flat profile that is easy to store and organize, while still providing full punching functionality when activated.
Solution Approach 2:
The punch device is designed with a flat, two-dimensional profile rather than a three-dimensional bulky structure. The lever and punch body are arranged in a planar configuration that minimizes vertical height and overall volume, making the device suitable for organized storage on surfaces or in compartments while maintaining punching effectiveness.
2Adaptability or versatility
If multiple mold pressing devices are collected, then various shapes can be punched, but the collection becomes disorganized and difficult to locate specific punches
Solution Approach 1:
Each punch device is designed with distinctive local features such as colored indicators, shaped handles, or numbered labels on the lever or punch body. These localized identification features allow users to quickly locate and identify specific punch devices among a collection, maintaining organization while preserving the ability to punch various shapes.
Solution Approach 2:
The punch devices are designed with universal storage characteristics that allow multiple different punch types to be stored together in an organized manner. The standardized flat profile and nesting capability enable various shape-specific punches to be collectively stored in a single organized system, making location and identification easier while maintaining shape variety.
3Shape
If the lever is positioned in a closed position parallel to the fissure, then the punch achieves a flat profile for easy storage, but the locking assembly must maintain this position while allowing quick access
Solution Approach 1:
The locking assembly is designed to automatically engage and disengage based on the lever's position. When the lever is moved to the closed position, the locking mechanism self-activates to secure the lever in place. When the lever is opened for punching, the locking assembly automatically releases. This self-service functionality maintains the flat profile while simplifying the locking mechanism to avoid complex manual operations.
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 reduces the size of the punch, allowing for convenient storage and easy recognition of shapes, while maintaining a stable and flat profile, enhancing usability and organization.
Implementation Method 1
The punch block is provided with a die movable along a first axis, with the punch block having first, second, and third shoulders. These shoulders respectively engage first, second, and third resilient members, springs, compression fittings, or biasing devices

AI summary
A punch for punching a sheet of material, the punch having a body formed with a fissure for receiving the sheet of material, a pivot shaft defining a pivot point, and a lever pivotably mounted about said pivot shaft has an open position and a closed position. A block is provided which is positionable between the lever and the body. The body is provided with longitudinal support ridges and the lever is provided with side ridges, with the pivot point positioned in substantially the same plane as the longitudinal support ridge so that when the punch is closed, the side ridges of the lever pass outside of the support ridges of the body in a nesting relationship, allowing the punch to form a flat profile when closed.
