Positioning Piece for Flat Part Alignment on Switch Cabinet Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrangements for positioning a flat part on a switch cabinet frame often result in insufficient alignment, requiring manual readjustment after initial placement, as the pre-positioning with a positioning piece does not ensure precise alignment with screw passages and threaded receptacles.
Innovation Solution
A positioning piece with a form-fitting section featuring three perpendicular contact surfaces that securely engages with the L-shaped edge of the flat part, allowing precise pre-positioning and alignment, and an elastic hook that frictionally engages the L-fold for stability, along with a bearing projection and sliding contour for secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple positioning piece is used to pre-position the flat part, then the ease of operation is improved, but the manufacturing precision deteriorates due to insufficient alignment
Solution Approach 1:
The positioning piece utilizes the vertical dimension by engaging the L-shaped edge from above, adding a third dimension of constraint to the traditional two-dimensional positioning. The form-fitting section with three contact surfaces creates precise positioning in the vertical direction while the hook engages the L-fold laterally, combining dimensional constraints to achieve both ease of operation and high alignment precision.
Solution Approach 2:
The positioning piece acts as an intermediary element between the flat part and the support structure. It mediates the connection by providing a form-fitting interface with the L-shaped edge and a separate engagement mechanism with the support structure, thereby ensuring precise alignment without requiring direct complex interfacing between the flat part and the support.
2Ease of operation
If the positioning piece is simplified for easy placement, then the ease of operation is improved, but the reliability deteriorates due to instability during fastening
Solution Approach 1:
The positioning piece is segmented into functionally distinct elements: a form-fitting section with three contact surfaces for precise positioning against the L-shaped edge, and a separate hook for engagement with the support structure. This segmentation allows each element to be optimized for its specific function - the form-fitting section ensures precise placement while the hook provides reliable stability during fastening operations.
Solution Approach 2:
The form-fitting section with its three contact surfaces performs preliminary positioning action by precisely locating the flat part relative to the support structure before fastening begins. This preliminary action ensures correct alignment is established early, and the subsequent hook engagement maintains this alignment stability throughout the fastening process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables convenient and precise pre-positioning of the flat part on the switch cabinet frame, ensuring accurate alignment and secure fastening without manual readjustment, while maintaining the sealing effect and IP protection class.
Implementation Method 1
The hook can be elastic, for example made of a plastic, and in a relaxed position have a distance from the form-fitting section that is smaller than the material thickness of the L-fold, so that the positioning piece is prestressed
Implementation Method 2
The hook can be elastic, for example made of a plastic, and in a relaxed position have a distance from the form-fitting section that is smaller than the material thickness of the L-fold, so that the positioning piece is prestressed and, if necessary, frictionally engages the L-fold
