Battery Post Terminal Fixing Structure for Balanced Multi-Directional Force Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery post terminal fixing structures struggle to provide balanced multi-directional force retention and are complex, costly, and difficult to assemble, especially in confined engine rooms, with existing solutions lacking balanced fastening and requiring extensive machining.
Innovation Solution
A fixing structure featuring left and right extended portions with inclined surfaces, a slope member with four leg parts, and a bolt inserted in an up-and-down direction, where the leg parts press the extended portions symmetrically to secure the battery post terminal, allowing balanced force distribution and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bolt is fastened from the lateral direction to fix the battery post terminal, then the fixing structure is simple, but it is difficult to perform the fastening work in an engine room with a large number of parts
Solution Approach 1:
The patent inverts the fastening direction from lateral (horizontal) to vertical, allowing the bolt to be inserted from above the battery post terminal. This inversion enables workers to access the fastening point from the top of the engine bay where space is more available, rather than attempting to work laterally among densely packed components. The clamp member is designed with a through-hole that receives the bolt vertically, and the inclined surfaces guide the clamp members together when the bolt is tightened from above.
2Ease of operation
If the battery post terminal has a complicated shape requiring bending to enable upper-side fastening, then the bolt can be fastened at the upper side, but the structure becomes complex and machining cost increases
Solution Approach 1:
The patent changes the geometric parameters of the clamp members by providing inclined surfaces on their inner surfaces. These inclined surfaces are designed with specific inclination angles that complement each other. When the clamp members are pressed together vertically by the bolt, the inclined surfaces convert the vertical pressing force into horizontal clamping force on the battery post. This parameter change allows the clamp members to maintain a simple, bendable shape while achieving the desired fastening function.
Solution Approach 2:
The clamp members are designed as flexible, bendable components rather than rigid fixed shapes. They can be elastically deformed during assembly to accommodate the battery post and then maintain a stable clamped position. The inclined surfaces enable the clamp members to dynamically adjust their position and apply uniform clamping force when pressed together by the vertically inserted bolt, eliminating the need for complex pre-formed geometries.
3Device complexity
If the fastening force acts from one side only, then the structure is simple, but the fixing strength is not balanced with respect to multi-directional forces during vehicle traveling
Solution Approach 1:
The patent divides the single fastening action into multiple contact points by using two clamp members (left and right) with inclined surfaces. Instead of one clamp member acting from one side, there are now two clamp members that contact the battery post at different locations. When the vertically inserted bolt tightens both clamp members simultaneously, it creates balanced clamping forces from multiple directions, improving the overall fixing strength and stability against multi-directional vibrations and impacts during vehicle operation.
Solution Approach 2:
The inclined surfaces of the clamp members are designed to counterbalance each other's forces. The left clamp member's inclined surface and the right clamp member's inclined surface are positioned and angled to provide symmetric counteracting forces. When the bolt applies vertical pressure, both clamp members generate horizontal clamping forces that balance each other, creating a stable, multi-directionally resistant fixing system that compensates for vibrations and impacts from various directions.
