Tilted Terminal Block Rib Layout for Lower-End Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal blocks used in a tilted position experience deformation at the lower end due to increased load, necessitating improved strength at this end.
Innovation Solution
The terminal block design includes a greater number of ribs at the lower end, which is subjected to higher load, with specific rib configurations to enhance strength and facilitate water drainage, while maintaining moldability and sealing integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal block is used in a tilted position with the first end lower than the second end, then the block main body can be installed in various orientations, but the first end experiences increased load and may deform
Solution Approach 1:
The patent applies local quality by increasing the number of ribs specifically at the first end (lower end) compared to the second end (upper end). This creates an asymmetric rib configuration where the first end has greater structural reinforcement to handle the increased load from tilted installation, while the second end maintains fewer ribs. This localized differentiation of structural properties resolves the contradiction by strengthening exactly where needed without unnecessarily increasing complexity elsewhere.
2Strength
If ribs are added to the first end to increase strength, then deformation is prevented, but the device complexity increases
Solution Approach 1:
The patent employs asymmetry by deliberately creating an unequal number of ribs between the first end and second end of the block main body. The first end has a greater number of ribs than the second end, forming an asymmetric pattern that optimizes structural strength where needed. This asymmetric design resolves the contradiction by providing the necessary strength enhancement through a simple, intuitive structural modification rather than complex reinforcement mechanisms.

AI summary
A terminal block according to one embodiment is configured to be used with a block body tilted such that a first end part in a second direction is positioned lower than a second end part. The first end part is provided with a plurality of first ribs extending in a first direction. The second end part is provided with a plurality of second ribs extending in the first direction. Furthermore, the number of the first ribs is larger than the number of the second ribs.
