Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connecting systems for electromagnetic contactors are costly and difficult to assemble due to the great disparity in connecting strips across different contactor models, leading to complex manufacturing and assembly challenges.
Innovation Solution
A connecting device with a conducting member having multiple relative positions for electric contact, allowing for various spatial combinations, comprising a first connecting piece electrically connected to the operating coil and a second piece accessible from outside the insulating body, with an 'L' shaped conducting member and a 'T' shaped second connecting piece, enabling flexible positioning and reduced piece variability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different connecting strips are used for each contactor model, then electrical connection reliability is ensured, but manufacturing cost and assembly complexity increase significantly
Solution Approach 1:
The patent applies universality by designing a single connecting strip that can be positioned in multiple locations along the insulating body to serve different contactor models. Instead of creating model-specific connecting strips, one universal strip design is used with variable positioning, thereby reducing manufacturing complexity while maintaining reliable electrical connections across all models.
2Manufacturing precision
If model-specific connecting strips are manufactured, then precise electrical connection is achieved, but manufacturing cost overruns occur
Solution Approach 1:
The patent reduces manufacturing cost by eliminating the need to produce multiple model-specific connecting strip variants. A single universal connecting strip design is manufactured and then positioned at different locations along the insulating body depending on the contactor model, thereby maintaining manufacturing precision while significantly simplifying production and reducing costs.
Solution Approach 2:
The patent incorporates preliminary action by providing predefined positioning options for the connecting strip along the insulating body. The strip is designed with features that allow it to be pre-positioned at specific locations corresponding to different contactor models, enabling precise electrical connections without requiring custom manufacturing for each model.
3Adaptability or versatility
If multiple connecting strip variations are produced, then adaptability to different contactor models is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent achieves adaptability to different contactor models through a single universal connecting strip that can be positioned at multiple locations along the insulating body. This eliminates the need to produce and manage multiple connecting strip variations, thereby maintaining versatility while reducing device complexity and inventory requirements.
