Elongate Caliber Bars for Punching Pressure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing devices for punching sheet-like cardboard materials require complex and labor-intensive setup for adjusting creasing lines to achieve optimal punching pressure, involving adhesive materials and resulting in waste from removable trimming tapes.
Innovation Solution
The device employs elongate caliber bars with a high length-to-width ratio, aligned with the side edge of the die, allowing for simplified adjustment of punching pressure by removing individual caliber bars, eliminating the need for creasing lines and adhesive use, and featuring a modular system with clamping connections for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If creasing lines are provided in the intermediate areas between the caliber blocks to improve punching result, then the punching quality is improved, but the setup complexity increases and requires adhesive materials
Solution Approach 1:
The patent extracts the adhesive materials and complex creasing line setup from the system by replacing them with simple caliber bars that can be directly positioned and fixed using clamping connections, eliminating the need for superglue and self-adhesive trimming tapes while maintaining punching quality
Solution Approach 2:
The patent changes the physical form of the caliber element from creasing lines (which require adhesive setup) to solid caliber bars with clamping connections, fundamentally altering how the intermediate areas are configured and simplifying the setup process
2Manufacturing precision
If self-adhesive trimming tapes or glued strip-shaped elements are used to create creasing lines, then the punching result is improved, but the handling effort and safety risks increase due to superglue
Solution Approach 1:
The patent removes adhesive materials (superglue and self-adhesive tapes) from the setup process entirely, replacing them with mechanical clamping connections that are safer and easier to handle, eliminating the need for protective measures against adhesive exposure
Solution Approach 2:
The caliber bars are designed with self-contained clamping connections that allow operators to easily assemble and disassemble them without requiring adhesive materials, making the setup process self-sufficient and safer
3Productivity
If trimming tapes are removed from the punching plate, then the setup is complete, but the tapes cannot be reused and become waste
Solution Approach 1:
The patent enables recovery and reuse of the caliber bars through their reversible clamping connections, allowing them to be removed, reused in different configurations, and not discarded as waste like the adhesive tapes in the prior art
Solution Approach 2:
The patent replaces the disposable adhesive tapes with durable, reusable caliber bars that can be repeatedly assembled and disassembled, eliminating the need to discard materials after single use
4Adaptability or versatility
If multiple caliber rods are provided in the intermediate area to enable fine adjustment of punching pressure, then the adjustability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the intermediate area into multiple positions where caliber bars can be independently placed and removed, allowing fine adjustment of punching pressure by selectively positioning caliber bars at different locations rather than using a single complex mechanism
Solution Approach 2:
The patent creates a dynamic configuration where caliber bars can be easily added or removed from multiple positions in the intermediate area, allowing the system to adapt punching pressure settings flexibly without permanent or complex fixed structures
