Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal blocks face issues with securing wires due to flat terminal ends, leading to potential disconnection and are costly and time-consuming to assemble due to numerous individual components.
Innovation Solution
A terminal block design featuring an insulating base seat and a clamping unit with a positioning member and resilient member, utilizing upper and lower press sections to securely clamp the wire, preventing withdrawal and integrating components for reduced assembly time and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat terminal member end portion is used, then the structure is simple, but the wire cannot be effectively secured and may be pulled away causing electrical disconnection
Solution Approach 1:
The terminal block employs a resilient pressing member with elastic deformation capability that dynamically adapts to the wire insertion process. The pressing member deforms elastically when the wire is inserted and then restores its shape to continuously apply clamping force, ensuring reliable wire securing without requiring complex mechanical structures
Solution Approach 2:
The pressing member features a curved pressing surface that contacts the wire, replacing the conventional flat terminal end. This curved surface provides better contact geometry for securing the wire, distributing clamping force more effectively and preventing wire pull-away while maintaining structural simplicity
2Ease of manufacture
If multiple individual components are used in the terminal block, then each component can be manufactured separately, but assembling these components is time-consuming and costly
Solution Approach 1:
The terminal block integrates the terminal member and pressing member as a single unified component, eliminating the need for separate assembly operations. This merged structure maintains the functional advantages of having both terminal and pressing elements while dramatically reducing assembly time and cost through simplified manufacturing and installation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The terminal block securely positions the wire with the clamping mechanism, facilitating smooth insertion and preventing disconnection, while reducing assembly time and cost through an integrated design.
Implementation Method 1
The resilient member has a base portion proximate to the second seat portion, and a resilient arm portion connected to the base portion and having a lower press section that is distal from the base portion and that extends toward the positioning member

AI summary
A terminal block is adapted to be connected to a wire, and includes an insulating base seat and a clamping unit. The insulating base seat includes first and second seat portions cooperating with each other to define a passage and a receiving space that communicates with the passage. The clamping unit includes a positioning member connected to the first seat portion and having an upper press section, and a resilient member having a base portion that is proximate to the second seat portion, and a resilient arm portion that is connected to the base portion, and that has a lower press section extending toward the positioning member. The upper and lower press sections are adapted for clamping resiliently an end segment of the wire therebetween.
