Solution Overview
Problem
The integration of a relay body with a connector without using a bus bar is necessary to reduce costs while still allowing connection to an electronic component, as using a bus bar for this purpose is not desirable and omitting it prevents connection.
Innovation Solution
An electromagnetic relay design where the connector is integrated with the relay body and an electronic-component connection terminal protrudes from the relay body, allowing direct connection to an electronic component without a bus bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bus bar is used for connection with both connector and electronic component, then connectivity is achieved, but cost increases and configuration becomes undesirable
Solution Approach 1:
The patent merges the connector and relay body into a single integrated unit, eliminating the need for a separate bus bar for connector connection. The connector is directly formed as part of the relay body structure, which resolves the contradiction by reducing both cost and configurational complexity while maintaining necessary connectivity functions.
Solution Approach 2:
The relay body is designed to serve multiple functions: it acts as both the relay housing and the connector body, while also providing mounting structures for electronic components. This multi-functionality eliminates the need for separate bus bars and reduces overall device complexity and cost.
2Ease of manufacture
If a bus bar is not used, then cost is reduced, but connection to electronic component becomes impossible
Solution Approach 1:
The electronic-component connection terminal is integrated directly into the relay body structure, combining the functions of the relay housing and the connection terminal. This integration maintains reliable connectivity to electronic components while eliminating the need for a separate bus bar, thus reducing cost without sacrificing connectivity.
Solution Approach 2:
The relay body itself serves as an intermediary structure that provides both the housing and the connection terminal. By making the relay body the mediator between the connector and the electronic component, the patent eliminates the need for an additional bus bar while ensuring reliable electrical connection.
