Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional punch tools are cumbersome and difficult to handle, especially when used in orientations other than flat on a work surface, and are not easily usable in inverted positions or with one hand, posing challenges for users with small hands or those needing to punch materials in various orientations.
Innovation Solution
A punch tool with a housing containing a punch and die mechanism that allows operation in multiple orientations, featuring a rotatable ramp system and wedge mechanism for actuation, enabling use on a work surface or in an inverted position, with handles for easy handling and a removable punch and die structure for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional punch tools are designed with a base to rest on a work surface and a pivotable top portion, then the punching function is achieved, but the device becomes bulky and difficult to handle
Solution Approach 1:
The punch tool is designed with symmetry allowing it to be used in both upright and inverted positions. The base can rest on the work surface or the top portion can rest on the work surface, effectively inverting the traditional orientation and eliminating the need for a fixed base-top configuration.
Solution Approach 2:
The punch tool is designed to perform punching operations in multiple orientations (upright and inverted positions). This multi-functionality allows the same device to serve different user needs and work scenarios without requiring separate tools.
2Ease of operation
If a spring member biases the punch and pivotable top in conventional punch tools, then the punching action is achieved, but actuation becomes more difficult for users
Solution Approach 1:
The spring biasing arrangement is configured to work effectively in both upright and inverted positions. The spring member maintains proper tension regardless of orientation, allowing easy actuation in either configuration without requiring excessive force.
3Adaptability or versatility
If conventional punch tools are designed to operate only in one orientation, then the mechanism is simple, but it is difficult to align material for various orientations
Solution Approach 1:
The entire punch tool assembly is designed with rotational symmetry about the punch axis, allowing the device to function correctly in both upright and inverted positions. This symmetrical design enables material alignment and punching operations from multiple orientations without complicating the core mechanism.
Solution Approach 2:
The punch tool is designed to accept and process materials in various orientations by allowing the housing to rest on the work surface in either upright or inverted position, providing universal functionality across different usage scenarios.
4Volume of moving object
If punch tools are designed as small form factor palm punches, then they are compact, but they are not amenable for use on a work surface
Solution Approach 1:
The punch tool combines features of both palm punches and work surface punches by being small enough to hold in one hand yet designed with a housing that can stably rest on the work surface in either upright or inverted position, providing versatility across different usage contexts.
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 versatile punching of materials in various orientations, including inverted positions, with improved ease of use and alignment, suitable for both handheld and surface-based operation, accommodating different sizes and types of materials.
Implementation Method 1
a spring member biases the punch and the pivotable top
Implementation Method 2
The lower ramp includes a wedge adapted to engage the punch and positioned between the punch and the lower housing
Implementation Method 3
The lower ramp includes a wedge adapted to engage the punch and positioned between the punch and the lower housing. Rotation of the lower ramp about the axis causes the wedge to engage the punch and raise the punch along a diagonal path

AI summary
A punch tool for the punching of a shape through a sheet of material. The punch tool includes a punch and a die portion disposed within a housing having a slot for receiving a sheet of material. A lower ramp is disposed within the housing and, when rotated, raises the punch to engage the die. The lower ramp may be rotated regardless of the orientation of the punch tool. Thus, the punch tool may be used even when in an inverted position.
