Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing program switches for printed circuit boards require dedicated production tools and storage for each number of poles, leading to high production and storage costs due to their unitary design.
Innovation Solution
A modular program switch with a one-pole module design featuring two connection elements for connecting to adjacent switches, allowing for the formation of a program switch arrangement with an arbitrary number of poles, reducing production costs and simplifying storage and sale.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If program switches are produced as units with predefined numbers of poles, then each specific pole configuration can be manufactured, but production costs increase due to requiring dedicated production tools for each number of poles
Solution Approach 1:
The program switch is divided into separate one-pole modules that can be independently manufactured and then connected together. Each module contains a single switching element and connection elements, allowing standardized production of identical units that can be combined in different quantities to create program switches with any number of poles, eliminating the need for dedicated production tools for each configuration
Solution Approach 2:
The one-pole module is designed as a universal building block that can serve multiple functions by being repeated and connected in series. The standardized connection elements (male and female connectors) enable the same module to be used regardless of the total number of poles required, making the production process universal across different product configurations
2Adaptability or versatility
If different numbers of poles require separate stock keeping, then each pole configuration can be stored and sold, but storage and sale costs increase
Solution Approach 1:
By segmenting the program switch into individual one-pole modules, the inventory requirement changes from storing multiple complete unit configurations to storing only one type of modular component. This single module type can be assembled into program switches with 2 poles, 3 poles, 4 poles, or any other number, dramatically reducing inventory variety while maintaining full configuration flexibility
Solution Approach 2:
Multiple identical one-pole modules are combined through their connection elements to form program switches with different numbers of poles. This combining approach allows a single standardized module design to fulfill multiple customer requirements, eliminating the need to maintain separate stock for each pole configuration
3Device complexity
If program switches are designed as units with predefined poles, then each unit is self-contained, but connection strength between adjacent switches decreases when using modular designs
Solution Approach 1:
The connection elements are designed with asymmetric male and female components that interlock in a specific orientation. The male connection element features a protruding structure while the female connection element has a corresponding recess, creating an asymmetric pairing that ensures proper alignment and maximizes connection strength when modules are joined together
Solution Approach 2:
The male connection element of one module is inserted into and nested within the female connection element of the adjacent module. This nesting arrangement creates a secure mechanical interlock where the protruding male element fits into the recess of the female element, providing robust mechanical coupling between modules while maintaining a compact overall structure

AI summary
The invention relates to a program switch for mounting on a printed circuit board comprising a housing, an insulator component with contact elements arranged thereon, and a switching element for contacting the contact elements. The housing has at least two connection elements for connecting the program switch to adjacent program switches to form a program switch arrangement having an arbitrary number of poles. Production and stock keeping and sale of the program switch are simple.
