Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in connecting electrical modules with positional tolerance fluctuations, particularly in screw connections, which complicates the assembly process and requires a solution that can compensate for these variations efficiently and cost-effectively.
Innovation Solution
A touch protection cover with a movable screw guide element monolithically connected to a protection housing, allowing for positional adjustment of screws to accommodate varying module positions, featuring a flexural hinge or spring joint for mobility and space-saving design, and a limited gap to prevent finger contact with electrical conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to fix the connection part and counterpart, then the electrical modules can be electrically connected, but the positional tolerance fluctuations between modules make the assembly process complicated and difficult
Solution Approach 1:
The screw guide element is designed to be movable relative to the protection housing, allowing it to dynamically adjust its position to accommodate tolerance variations during assembly. This dynamic capability enables the screw to be guided into the correct position even when there are positional deviations between connected modules.
Solution Approach 2:
The screw guide element acts as an intermediary component between the screw and the protection housing. It mediates the positioning function by providing a movable guide that compensates for tolerance fluctuations, thereby simplifying the assembly process while maintaining reliable electrical connections.
2Adaptability or versatility
If multiple separate components are used for the touch protection cover, then each component can be optimized for its specific function, but the number of components increases manufacturing complexity and cost
Solution Approach 1:
The screw guide element and protection housing are monolithically connected as a single integrated component. This merging reduces the total number of separate parts while maintaining the protective function and the movable screw guide functionality, thereby simplifying manufacturing and assembly.
Solution Approach 2:
The integrated component serves multiple functions: the protection housing provides electrical insulation and protection, while the monolithically connected screw guide element provides both structural support and movable guidance for the screw. This multi-functionality reduces the need for separate specialized components.
3Device complexity
If the screw guide element is fixed in a predetermined position, then the structure is simple and stable, but it cannot compensate for positional tolerances during assembly
Solution Approach 1:
The screw guide element is designed with movable capability relative to the protection housing, enabling it to adapt its position to compensate for tolerance variations. This dynamic design maintains relatively simple structure while achieving the required adaptability for tolerance compensation.
