Damping Element for Electric Vehicle Battery Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing energy supply systems for two-wheeled vehicles with electric drives often require significant user effort to insert and secure the electrical energy store, leading to a risk of damaging electrical contacts and compromising the energy supply.
Innovation Solution
A retaining system with a deformable damping element or magnet system between the energy store and the mounting, allowing for gentle insertion and automatic locking via weight force or magnetic attraction, reducing the need for user effort and ensuring secure connection without damaging components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking bar is pressed to the rear to secure the energy store, then the locking connection is achieved, but great strength is required and damage risk increases
Solution Approach 1:
A damping element is introduced as an intermediary component between the energy store and the mounting. This damping element absorbs the impact during insertion, enabling the locking bar to engage with the receptacle without requiring excessive force from the user, thus resolving the contradiction between reliable locking and ease of operation
Solution Approach 2:
The damping element is positioned in advance between the energy store and the mounting to cushion the impact before the locking bar engages with the receptacle. This prior cushioning prevents damage during insertion while ensuring the locking connection is achieved, addressing both reliability and ease of operation
2Reliability
If the locking bar is pressed to the rear, then the locked state is achieved, but electrical contacts may be damaged
Solution Approach 1:
The damping element is positioned beforehand between the energy store and the mounting to absorb the impact force during insertion. This cushioning occurs before the locking bar engages the receptacle, preventing the transmission of damaging forces to the electrical contacts while ensuring the locked state is achieved
Solution Approach 2:
The damping element serves as a mediator that absorbs and dissipates impact energy during the insertion process. This intermediary protection prevents harmful forces from reaching the electrical contacts between the energy store and the mounting, while still allowing the locking mechanism to function reliably
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and secure insertion and removal of the energy store with minimal user effort, preventing damage to contacts and ensuring a reliable energy supply by using a deformable damping element or magnet system to facilitate automatic locking.
Implementation Method 1
The deformable damping element is configured to damp a motion during insertion of the element into the mounting via self-deformation
Implementation Method 2
The intermediate element is configured to carry out a damped motion during the insertion, so that gentle accommodation of the element in the mounting is possible
Implementation Method 3
A retaining system with a deformable damping element or magnet system between the energy store and the mounting, allowing for gentle insertion and automatic locking via weight force or magnetic attraction

AI summary
A retaining system for retaining and releasing an element, in particular an electrical energy store. The retaining system includes a mounting that is configured to accommodate and fix the element, the mounting being configured to removably accommodate the element in the mounting, and an intermediate element that is situated between the element and the mounting and configured to allow a damped motion, in particular for gentle accommodation, of the element in the mounting. The mounting includes a locking bar that is configured to be accommodated in a receptacle in a locking position, or the mounting includes a receptacle that is configured to accommodate a locking bar in a locking position.
