Bayonet Locking Ring Two-Part Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of bayonet-type locking rings for circular electrical connectors is complex and expensive due to the need for intricate molds and machining processes, which result in high costs and material inefficiencies.
Innovation Solution
A bayonet-type locking ring is designed as two separate parts with a joint plane between them, allowing for simpler and less expensive manufacturing without complex tools, and using thermoplastic or metal materials based on performance needs, optimizing design and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bayonet locking ring is produced as a one-piece molded part with ramps, then the locking function is achieved, but the mold becomes complex and expensive due to undercuts requiring collapsible cores
Solution Approach 1:
The locking ring is divided into two separate parts: a body part and a ramp part. The ramp part is produced separately and then assembled to the body part. This segmentation eliminates the need for complex collapsible cores in the mold, as the ramp features are no longer part of the main molded structure but are added as a separate component.
2Manufacturing precision
If a bayonet locking ring is produced by machining, then the ramps can be precisely cut, but the production process becomes complex and costly requiring combination machines and numerical control
Solution Approach 1:
The locking ring is segmented into a body part and a ramp part. The body part can be produced by simpler molding processes, and the ramp part is separately manufactured and assembled. This eliminates the need for complex combination machining operations and numerical control systems while maintaining the necessary precision through the separate manufacturing and assembly process.
3Strength
If a bayonet locking ring is produced as a one-piece machined part, then the structural integrity is maintained, but material waste increases due to the machining process
Solution Approach 1:
The locking ring is divided into a body part and a ramp part that are assembled together. The body part can be produced by molding with minimal material waste, and the ramp part is separately manufactured. This segmented approach significantly reduces material waste compared to traditional machining of a one-piece part, while the assembled structure maintains the necessary structural integrity for locking applications.
