Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for wire bundle ends in electric motor production face challenges in reliably cutting to a specified length without wire chips falling into the stator, especially in limited spaces.
Innovation Solution
A cutting device with a base body having chambers and slidably mounted cutting elements with blades and covers, forming a closed collecting space for cut wire pieces, allowing safe storage until the cutting element returns to its starting position, and featuring modular design for efficient operation in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pliers or conventional cutting devices are used to cut wire bundle ends, then cutting can be performed, but wire fragments may fall into the stator and cutting reliability in confined spaces is compromised
Solution Approach 1:
The invention converts the potentially harmful loose wire fragments into contained debris by designing a collection chamber that captures and retains cut wire pieces. The chamber transforms the harm of falling fragments into a controlled collection system where fragments are safely stored and can be removed together with the cutting element.
Solution Approach 2:
The cutting element incorporates a cover that forms a flexible or removable closure for the collection chamber. This cover can be moved to open or close the chamber, allowing wire fragments to be contained during cutting and then discharged when needed, providing a simple yet effective containment mechanism.
2Manufacturing precision
If multiple wire bundle ends are cut separately, then cutting precision can be maintained, but production time increases
Solution Approach 1:
The invention merges multiple cutting operations into a single action by providing a base body with multiple chambers and cutting elements that can simultaneously cut several wire bundle ends. The chambers are arranged to receive multiple wire bundles, and a single actuation of the cutting elements performs all cuts at once, maintaining precision while dramatically reducing production time.
Solution Approach 2:
The cutting device is segmented into multiple independent chambers, each capable of receiving and cutting a wire bundle end. This segmentation allows parallel processing of multiple wire bundles while maintaining the precision of individual cutting operations, as each chamber functions independently with its own cutting element.
3Object-affected harmful factors
If a closed collection chamber is formed to prevent wire fragments from falling, then wire fragment containment is improved, but device complexity increases
Solution Approach 1:
The cutting element serves multiple functions: it performs the cutting action and simultaneously forms the collection chamber with its cover. The cover that closes the chamber is integrated into the cutting element itself, eliminating the need for separate containment structures and reducing overall device complexity while maintaining effective wire fragment containment.
4Ease of operation
If cutting is performed in confined spaces, then access to stator terminals is achieved, but cutting reliability and safety are compromised
Solution Approach 1:
The collection chamber is nested within the base body, and the cover is integrated into the cutting element which moves within the chamber. This nested structure allows the entire cutting and containment system to be compact, enabling operation in confined spaces around stator terminals while maintaining safety through the contained collection chamber that prevents wire fragments from scattering in the confined area.
