Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lighted safety whips often experience electrical connection issues at the mounting base or lamp socket, leading to premature failures and flickering or non-illumination of the lamp.
Innovation Solution
A secure electrical interface is designed with a mounting base that includes a contact spring, insulation sleeve, and grounding collar to ensure reliable connections between the flexible shaft and electrical connector, routing ground and power wires through the mast, and using an insulation cap to maintain electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connection methods are used at the mounting base or lamp socket, then the device structure remains simple, but electrical connection reliability deteriorates leading to premature failures and flickering
Solution Approach 1:
The electrical interface is divided into separate functional components: a contact spring for electrical connection, an insulation sleeve for electrical isolation, and a grounding collar for ground connection. Each component performs a specific function, allowing the system to achieve reliable electrical connections while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The contact spring is pre-formed with specific mechanical properties to ensure consistent electrical contact pressure. The insulation sleeve and grounding collar are pre-assembled in specific configurations before final installation, ensuring proper electrical connections are established before the product enters service.
2Stability of the object's composition
If simple electrical connection methods are used, then manufacturing remains easy, but connection stability deteriorates causing lamp flickering or non-illumination
Solution Approach 1:
The electrical connection system is segmented into distinct components (contact spring, insulation sleeve, grounding collar) that can be manufactured independently using standard processes, then assembled through simple insertion and engagement actions, achieving stable connections without complex fabrication.
Solution Approach 2:
Each component is designed with specific local properties: the contact spring has elastic properties for consistent contact pressure, the insulation sleeve has non-conductive properties for electrical isolation, and the grounding collar has conductive properties for ground connection. These localized qualities ensure stable electrical connections through simple assembly.
3Reliability
If traditional mounting methods are used, then the device structure remains simple, but electrical connection security deteriorates leading to connection failures
Solution Approach 1:
The mounting base incorporates segmented electrical connection components that can be independently installed and secured. The contact spring, insulation sleeve, and grounding collar are separate elements that provide secure electrical connections through their specific mechanical and electrical properties, enhancing reliability without requiring a completely complex mounting structure.
Solution Approach 2:
The insulation sleeve acts as an intermediary component between the contact spring and grounding collar, providing both electrical isolation and mechanical positioning. This intermediary element secures the electrical connections by preventing direct contact between conductive parts while maintaining proper alignment and contact pressure.
