Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary battery electrode cutting devices face issues with tolerance between upper and lower blades leading to non-uniform cut surfaces and the occurrence of burrs, which affect the quality of the cutting process.
Innovation Solution
A secondary battery electrode surface pressure cutting device utilizing an adjustment module to precisely adjust the upper blade's position relative to the lower blade, ensuring optimal surface pressure and preventing burrs and non-uniformity by using a threaded part, spring, adjustment member, and O-ring configuration to finely move the upper blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a scaffold-type cutting device is used to cut the electrode, then the cutting process can be performed, but tolerance between upper and lower blades causes non-uniform cut surfaces and burrs
Solution Approach 1:
The patent applies the Dynamics principle by making the upper blade adjustable relative to the lower blade through a blade adjustment mechanism. This allows the blade assembly to be dynamically repositioned to compensate for tolerance accumulation during repeated cutting operations, maintaining consistent cut surface quality and preventing burr formation by ensuring proper blade alignment stability.
Solution Approach 2:
The patent implements Parameter changes by providing adjustable clearance between the upper and lower blades through the blade adjustment mechanism. This allows operators to modify the positional parameters of the upper blade to compensate for wear and tolerance, thereby maintaining manufacturing precision and eliminating non-uniform cut surfaces caused by blade misalignment.
2Stability of the object's composition
If the lower blade is fixed to prevent shape deformation, then cutting stability is improved, but adjustment of blade clearance becomes difficult
Solution Approach 1:
The patent applies Segmentation by separating the adjustment function from the lower blade assembly and placing it on the upper blade assembly instead. The blade adjustment mechanism is integrated into the upper blade holder, allowing independent adjustment of the upper blade position while the lower blade remains fixed and stable, thus maintaining both shape stability and ease of clearance adjustment.
3Manufacturing precision
If the upper blade is made adjustable to compensate for tolerance, then cut surface quality is improved, but device complexity increases
Solution Approach 1:
The patent implements a relatively simple dynamic adjustment mechanism on the upper blade holder that allows the upper blade to be repositioned to compensate for tolerance. This dynamic capability enables maintenance of cut surface uniformity without requiring complex mechanisms, as the adjustment system is integrated directly into the upper blade assembly rather than the entire cutting device.
