Inclined Storage Battery Terminal for Obstruction-Free Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage battery connection terminals face difficulties in coupling a clamping nut due to lateral placement of clamping bolts, leading to obstruction by neighboring vehicle components and potential corrosion, which damages the clamping bolt and reduces durability.
Innovation Solution
A storage battery connection terminal with inclined upper and lower plates, a silicon-coated clamping nut, and a z-bending neck part, allowing easy coupling of the clamping nut from an inclined direction, preventing excessive tightening, and enhancing the clamping force and durability by using a single panel manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamping bolt is positioned on the lateral side of the storage battery, then the connection terminal can be compactly designed, but workers face difficulties in performing connection work and are obstructed by other vehicle parts
Solution Approach 1:
The clamping bolt is repositioned from a lateral arrangement to an inclined arrangement, changing the spatial dimension of access. This allows the clamping nut to be coupled from an inclined direction rather than strictly laterally, eliminating obstructions from neighboring vehicle parts while maintaining compact design
2Ease of operation
If the clamping bolt is positioned in an inclined or vertical direction to ease coupling, then connection work becomes easier, but the upper edges of the clamping bolt are damaged and corrosion occurs
Solution Approach 1:
The upper edges of the clamping bolt are subjected to local quality enhancement through coating or plating treatment. This protective layer prevents corrosion and damage at the specific vulnerable locations (upper edges) while maintaining the inclined positioning that provides ease of operation
Solution Approach 2:
The clamping bolt combines different materials or material treatments - the base bolt material provides mechanical strength, while a protective coating or plating layer provides corrosion resistance. This composite structure allows the bolt to withstand both the operational requirements of inclined positioning and the environmental requirements of vibration and moisture resistance
3Reliability
If the clamping bolt is tightly secured to prevent loosening, then connection stability improves, but the post terminal may be damaged by excessive tightening
Solution Approach 1:
A feedback mechanism is introduced through the elastic deformation of the insertion unit. As the clamping force increases, the insertion unit deforms elastically, providing visual or tactile feedback that helps the worker stop tightening at the appropriate point, preventing excessive tightening that could damage the post terminal while ensuring sufficient clamping force for stable connection

AI summary
The storage battery connection terminal comprising: an insertion unit formed in a shape of a curved; a clamping unit formed by extending end portions of the insertion; and a power withdrawal unit formed to be extended from the other end portion of the insertion unit, in which the insertion unit, the clamping unit and the power withdrawal unit are manufactured by molding a single panel. The clamping unit includes a lower plate formed to be inclined by extending one end portion of the insertion unit so as to support the clamping bolt, and an upper plate formed to be inclined by extending the other end portion of the insertion unit so as to be disposed in parallel to the lower plate, on which the clamping nut is rested.
