Wire Terminal with Rear Laminated Portion for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire terminals with easily breakable portions for separation suffer from reduced vibration resistance due to concentrated vibration loads, which can lead to premature breakage and separation issues during vehicle dismantling.
Innovation Solution
The wire terminal design includes a laminated portion connected to a base plate via an easily disassemblable portion, positioned rearward from the fixing portion, with guides to suppress displacement and a shorter length between side edges, allowing for controlled separation and reduced vibration load on the easily disassemblable portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the easily disassemblable portion is positioned near the front end of the base plate to facilitate separation, then the wire can be easily separated from the terminal, but the vibration load on the easily disassemblable portion increases and vibration resistance decreases
Solution Approach 1:
The patent positions the easily disassemblable portion in the rear part of the base plate, utilizing the longitudinal dimension to relocate the separation function away from the vibration-prone front end. This spatial reconfiguration allows the separation function to be performed at a location experiencing lower vibration loads, thereby resolving the contradiction between ease of separation and vibration resistance.
Solution Approach 2:
The patent creates a local structural difference by positioning the easily disassemblable portion in the rear part of the base plate with a specific configuration (shorter length between side edges) that facilitates separation, while the front end maintains a different structural characteristic optimized for vibration resistance. This local differentiation allows each part to optimize for its specific function.
2Ease of operation
If the length between side edges of the easily disassemblable portion is shortened to facilitate breaking, then the wire separation becomes easier, but the structural integrity may be compromised
Solution Approach 1:
The easily disassemblable portion is designed with a localized structural characteristic (shorter length between side edges) specifically at the location where separation is needed, while the rest of the terminal structure maintains its full dimensional integrity. This localized modification allows easy separation without compromising the overall structural strength of the terminal.
Solution Approach 2:
The terminal structure is segmented into distinct functional zones: the front end for vibration resistance, the rear part for easy separation, and the laminated portion for electrical connection. The easily disassemblable portion acts as a deliberate weak point or segmentation that allows controlled separation without affecting the integrity of other structural segments.
3Reliability
If the guides are added to suppress displacement of the laminated portion, then the structural stability during vibration is improved, but the device complexity increases
Solution Approach 1:
The guides act as intermediary elements that mediate between the laminated portion and the base plate, allowing controlled relative movement in the pulling direction while preventing displacement in the lamination direction. This intermediary structure provides a simple yet effective mechanism for maintaining stability without requiring complex constraint systems.
