Wall-Mounted Signaling Component Base Design for Compact Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for electrical control and signaling components with two-point fixing means face challenges in meeting dimensional constraints due to the need for larger base dimensions and complex designs, making them costly and difficult to manufacture.
Innovation Solution
A control and/or signaling component with a base that includes two electrical blocks, where the central block is actuated indirectly and the lateral block provides mechanical actuation, allowing for smaller locking means and more space for fixing screws, enabling compliance with dimensional constraints without the need for complex designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-point fixing means are used with the base centered on the activation button, then the fixing device is simpler, but the base dimensions become larger to meet alignment requirements
Solution Approach 1:
The invention repositions the two fixing points from being aligned with the central activation button to being located at lateral corners of the base. This spatial rearrangement in the horizontal plane allows the fixing screws to be positioned at the extremities of the base, maximizing the utilization of available space and enabling compact base dimensions while maintaining proper alignment with wall mounting holes.
2Strength
If locking means are placed in the central part of the base for strong attachment, then the attachment strength is improved, but the space for fixing screws is reduced
Solution Approach 1:
The invention divides the base into functional zones: lateral corners are dedicated to fixing screw attachment points, while the central region is reserved for the activation button and electrical blocks. This segmentation allows locking means to be positioned laterally rather than centrally, providing both strong attachment and adequate space for fixing screws without spatial conflict.
3Area of stationary object
If the base is designed to receive multiple electrical blocks in a compact arrangement, then the dimensional constraints are met, but the design becomes more complex
Solution Approach 1:
The invention creates a universal base design with standardized corner mounting holes and a modular structure that can accommodate various combinations of electrical blocks (one or two blocks, with or without activation buttons). The lateral corner fixing pattern provides a consistent interface that works across different configurations, reducing design complexity despite the ability to receive multiple block types.
