Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing printed circuit boards to plug bodies are complex and space-consuming, requiring screws which complicate assembly and consume valuable space.
Innovation Solution
A space-saving assembly that secures a printed circuit board to a plug body using a contact element with a holding face and a securing member that transfers to a securing position in a positive fit manner, eliminating the need for screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to secure the printed circuit board to the plug body, then the connection strength is improved, but the device complexity and space consumption increase
Solution Approach 1:
The patent extracts and eliminates the screw fastening system from the assembly, replacing it with an integrated securing member that is part of the contact element structure. This removes the need for separate screws and simplifies the assembly process while maintaining connection strength through the positive fit mechanism between the securing member and the printed circuit board.
Solution Approach 2:
The patent merges the securing function with the contact element structure by integrating the securing member into the contact element. This combination eliminates the need for separate fastening components and reduces assembly complexity while maintaining the required connection strength between the printed circuit board and plug body.
2Strength
If screws are used to secure the printed circuit board to the plug body, then the connection strength is improved, but the space consumption increases
Solution Approach 1:
The patent removes the screw fastening system and replaces it with a compact securing member integrated into the contact element. This extraction eliminates the space required for screws and their associated mounting features, reducing overall space consumption while maintaining connection strength through the positive fit mechanism.
Solution Approach 2:
The patent implements a nested structure where the securing member is integrated within the contact element structure. The securing member is positioned within the housing and works in conjunction with the contact element, creating a compact nested arrangement that reduces space consumption while maintaining connection strength.
3Strength
If screws are used to secure the printed circuit board to the plug body, then the connection strength is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent extracts the screw fastening system and replaces it with an integrated securing member that is part of the contact element structure. This eliminates the need for separate screw fastening operations and simplifies the manufacturing process while maintaining connection strength through the positive fit mechanism.
Solution Approach 2:
The patent merges the securing function with the contact element structure, creating an integrated component that simplifies manufacturing. The securing member is formed as part of the contact element, eliminating the need for separate fastening operations and improving ease of manufacture while maintaining connection strength.

AI summary
Shown is an assembly or securing a printed circuit board to a plug body, having a contact element with a holding face facing against a plugging direction of the contact element, and a securing member, that can be transferred into a securing position, in which the printed circuit board is secured by the securing member in a positive fit manner against the plug direction at the holding face. Further shown is a method of securing a printed circuit board at the plug body, wherein a holding face of a contact element facing against a plug direction is inserted through an opening in the printed circuit board and subsequently a securing member is transferred to a securing position, in which the printed circuit board is secured by the securing member in a positive fit manner against the plug direction at the holding face.
