Adjustable Modular Housing Rails for Electrical Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical component fixing frames in boxes do not efficiently manage internal space, adapt to component shapes, or facilitate easy mounting and handling of electrical components, often requiring inappropriate spacings or alternative boxes.
Innovation Solution
A box with a modular fixing frame comprising parallel fixed rails and transverse rails that can be adjusted in spacing and orientation, allowing for easy adaptation to various electrical component sizes through screwing or clipping mechanisms, and featuring channels and clips for secure mounting and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed spacing pads are used in the box bottom, then the box structure is simple and easy to manufacture, but the spacing is inappropriate for various sizes of printed circuits or fixing plates
Solution Approach 1:
The fixing frame is segmented into multiple adjustable transverse rails that can be independently positioned along the fixed rails. This segmentation allows each rail to be placed at optimal intervals to match different component sizes, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The transverse rails are designed to be adjustable and repositionable along the fixed rails, transforming the static fixed-spacing structure into a dynamic configurable structure. This allows the spacing to be adapted to different component sizes while maintaining a relatively simple overall frame structure.
2Adaptability or versatility
If multiple fixed spacing pads are provided in the box, then different spacings are offered, but this requires multiple boxes for different component sizes
Solution Approach 1:
The fixing frame with adjustable transverse rails serves multiple functions: it can accommodate printed circuits of various sizes, fixing plates of different dimensions, and components with varying spacing requirements. This universal design eliminates the need for multiple specialized boxes, reducing the quantity of boxes required while maintaining versatility.
3Strength
If transverse rails are screwed to fixed uprights, then the structure is stable and strong, but the internal space is not efficiently managed and handling is difficult
Solution Approach 1:
The fixing frame uses segmented transverse rails that can be independently adjusted and positioned, allowing efficient utilization of internal space. The segmented structure also improves ease of handling compared to rigid welded structures, while maintaining structural strength through the screw connection system.
Solution Approach 2:
The transverse rails extend in the horizontal dimension between the fixed uprights, creating a modular grid structure that efficiently manages internal space. This dimensional arrangement allows components to be mounted at optimal positions while maintaining structural integrity through the upright-rail connection system.
4Adaptability or versatility
If the box has fixed spacing pads, then manufacturing is simple, but adapting the chassis shape to component nature and shape is difficult
Solution Approach 1:
The transverse rails are designed to be adjustable in position along the fixed rails, transforming the static fixed-spacing structure into a dynamic configurable structure. This allows the chassis shape to be adapted to different component shapes and sizes without requiring complex custom manufacturing, maintaining ease of manufacture while improving adaptability.

AI summary
The box (1) has identical fixed and transverse rails (20a, 20b, 21a, 21b) made of synthetic material. The fixed rails have a reception unit with channels for fixing the transverse rails, an electrical or electronic component e.g. printed circuit board, or an mounting plate. The transverse rails perpendicularly extends between the fixed rails from the unit for fixing of the component or the plate. A fixing frame has collar elements fixed on the rails by screwing. Each transverse rail has a stud (16) pressed on the base (10) of the box during assembly of the component or the plate.
