Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal blocks face challenges in meeting strict tolerance requirements due to limited guidance and support for electrical terminals, leading to alignment issues and movement restrictions.
Innovation Solution
The design incorporates guiding formations around the electrical terminals, which can be pyramid or conical in shape, extending from the terminal block body to provide enhanced guidance and support during insertion and post-insertion, ensuring precise alignment and stability within the junction box housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional terminal block design is used, then device complexity is reduced, but manufacturing precision and alignment accuracy deteriorate due to limited guidance for electrical terminals
Solution Approach 1:
The terminal block structure is segmented into functional components: the body, multiple guiding formations (pyramidal and conical), and support beams. Each guiding formation is a separate geometric element that provides specific guidance functions for different portions of the electrical terminals, allowing precise alignment without requiring a completely redesigned monolithic structure.
Solution Approach 2:
The guiding formations are designed to preliminarily guide the electrical terminals into correct alignment positions before final insertion into the terminal block body. The pyramidal guiding formations on the body surface and the conical guiding formations extending from support beams pre-position the terminals, ensuring accurate alignment is achieved before the terminals are fully seated.
2Manufacturing precision
If guiding formations are added to enhance terminal support, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
Multiple guiding functions are merged into a unified terminal block structure. The pyramidal guiding formations on the body surface and the conical guiding formations from support beams work together as an integrated guidance system. The support beams themselves serve dual purposes as both structural support elements and carriers for conical guiding formations, reducing the need for separate components.
Solution Approach 2:
The support beams serve multiple functions: they provide structural support for the terminal block body, carry the conical guiding formations for terminal alignment, and extend to connect with lower guiding formations. The guiding formations themselves serve both as alignment guides and as positional references for the terminals during insertion.
3Stability of the object's composition
If multiple guiding formations are used, then stability and alignment are improved, but ease of manufacture deteriorates
Solution Approach 1:
The guiding formations utilize conical and pyramidal geometric shapes with tapered surfaces. These curved and angled surfaces naturally guide the electrical terminals into correct alignment through contact with the tapered faces, providing self-aligning functionality that stabilizes terminal position during insertion without requiring complex adjustment mechanisms.
4Measurement precision
If guiding formations extend from the body, then alignment accuracy improves, but device complexity increases
Solution Approach 1:
Different regions of the terminal block structure have different guiding qualities tailored to specific needs. The pyramidal guiding formations on the body surface provide guidance at the upper insertion point, while the conical guiding formations on the support beams provide guidance at lower points. Each local area has optimized guiding geometry appropriate for its specific function in the terminal insertion process.

AI summary
An electrical terminal block may include an electrical terminal that may include a first portion configured for connection with a connector and a second portion that may be configured for connection with a circuit board. The terminal block may include a body that may be configured to support the electrical terminal. The terminal block may include a guiding formation that may extend from the body and may be disposed at least partially around the first portion of the electrical terminal.
