Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technology requires separate printed boards for different types and numbers of relays, leading to increased costs and complex inventory management due to the need for distinct design and manufacturing processes.
Innovation Solution
A printed board design that allows for the selective mounting of two first relays and one second relay, utilizing common and exclusive through-holes for coil, fixed, and movable terminals, enabling flexible relay configuration without the need for multiple printed boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate printed boards are fabricated for different types and numbers of relays, then relay configuration flexibility is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The printed board is designed with a universal layout that can accommodate different types and numbers of relays (1C contact relay or 2C contact relay) through selective mounting. The board includes common through-holes and relay-exclusive through-holes that allow flexible configuration without requiring separate board designs for different relay combinations.
2Adaptability or versatility
If separate printed boards are fabricated for different types and numbers of relays, then relay configuration flexibility is improved, but inventory management complexity increases
Solution Approach 1:
A single universal printed board design replaces multiple specialized board designs, enabling the same board to be used for different relay configurations (two 1C contact relays or one 2C contact relay). This standardization simplifies inventory management by reducing the number of different board types that need to be tracked and managed.
3Adaptability or versatility
If separate printed boards are fabricated for different types and numbers of relays, then relay configuration flexibility is improved, but production cost increases
Solution Approach 1:
The printed board employs a universal design that can be produced in larger volumes for a single configuration type, reducing per-unit manufacturing costs compared to producing multiple specialized board variants. The board achieves relay configuration flexibility through selective component mounting rather than through multiple board design variants.
4Manufacturing precision
If multiple printed boards are designed and manufactured for different relay configurations, then relay-specific connection precision is improved, but manufacturing process complexity increases
Solution Approach 1:
The printed board includes specifically positioned through-holes (common and relay-exclusive) that ensure precise connections for different relay types. The universal design maintains manufacturing precision by providing dedicated connection points for each relay configuration while avoiding the need for multiple specialized board designs.

AI summary
In this printed circuit board, on which two first relays and a single second relay can be selectively mounted, two shared through-boles which are shared by the connection of the terminals of the first relays and the connection of the terminal of the second relay and two first relay-dedicated through-boles which are used only for the connection of the terminals of the first relays are disposed in a line along a prescribed direction.
