Solution Overview
Problem
Existing modular systems for producing electronic devices face challenges in easy assembly and variable equipping with connections or functional components, limiting their flexibility and cost-effectiveness.
Innovation Solution
A modular system featuring attachment parts with a pitch corresponding to a predetermined smallest division unit or its integer multiple, allowing for variable combinations to create different lengths and functions, which can be guided into a housing to securely hold a circuit board in place, enabling flexible configuration and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a modular system with fixed attachment parts is used, then the assembly process becomes standardized and simpler, but the flexibility to configure different electronic devices is reduced
Solution Approach 1:
The housing is divided into modular sections with standardized openings that can accommodate different combinations of attachment parts. Each attachment part is a separate, interchangeable component that can be selectively installed to create different device configurations while maintaining standardized assembly procedures.
Solution Approach 2:
The attachment parts are designed with universal mounting interfaces that allow the same basic component type to serve multiple functions across different device configurations. The standardized opening dimensions and attachment part geometries enable a single set of modular components to adapt to various electronic device requirements.
2Adaptability or versatility
If attachment parts are made highly configurable to meet various application needs, then device versatility increases, but assembly complexity and costs increase
Solution Approach 1:
While maintaining overall standardized dimensions, the attachment parts incorporate local variations in features such as connection types, mounting hole patterns, or functional elements only where specifically needed for particular applications. This allows customization at local points without compromising the global modular standardization that simplifies assembly.
3Ease of manufacture
If a standardized modular system is used, then production costs decrease, but the ability to accommodate specific application requirements is limited
Solution Approach 1:
The modular system is designed to be dynamically configurable, allowing the same standardized housing and attachment part library to be recombined in different configurations for specific applications. The standardized interfaces enable rapid reconfiguration without requiring custom tooling or complex assembly procedures, maintaining cost-effectiveness while adapting to application needs.

AI summary
A modular system for producing an electronic device (1) comprises a housing (10), which forms an accommodating space (15), and a printed circuit board (12) which can be inserted into the accommodating space (15) of the housing (10) along an insertion direction (E) and is accommodated in the accommodating space (15) in an assembly position. Attachment parts (13, 13A-13G) which can be connected to the printed circuit board (12) each have, when viewed along the insertion direction (E), a division (X1, X2, X3, X6, X9) which corresponds to a predetermined smallest division unit (X1) or an integer multiple of the predetermined smallest division unit (X1). Each attachment part (13, 13A-13G) has a first guide device (133) for guiding on a second guide device (107) of the housing (10). A combination of attachment parts (13, 13A-13G) can be connected to the printed circuit board (12) in a manner aligned side-by-side along the insertion direction (E).
