Vehicle Starter Protection Skid Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle engine rooms, the proximity of batteries and electrical components like starters poses a risk of damage during collisions, and existing solutions do not adequately address the reduction of noise and vibration associated with engine and transmission operations.
Innovation Solution
A protection device featuring a skid block attached to a bracket that extends between the battery and electrical components, with a flat facing surface to absorb impact and reduce damage, and a support case to mitigate battery damage by directing force away from the electrical component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the battery is disposed close to the starter for space efficiency, then the engine room layout is optimized, but the starter becomes vulnerable to damage during vehicle collisions
Solution Approach 1:
A protection block is introduced as an intermediary component between the battery and the starter. This protection block absorbs collision forces and prevents direct impact on the starter, thereby resolving the contradiction between close spatial arrangement and collision protection.
Solution Approach 2:
The protection block is pre-installed in the engine room layout to provide beforehand cushioning against potential collision damage. By positioning this protective element in advance, the starter is shielded from future collision impacts while maintaining the optimized space utilization.
2Stability of the object's composition
If rigid mounting structures are used to secure electrical components, then installation stability is improved, but noise and vibration from engine operations increase
Solution Approach 1:
The mounting structure parameters are changed from rigid to flexible by incorporating elastic elements. This parameter change allows the mounting to maintain stability while absorbing vibrations and reducing noise transfer, thus resolving the contradiction between stability and harmful factor generation.
3Reliability
If complex protection structures are added to protect the starter, then collision damage protection is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The protection function is extracted as a separate, independent protection block component rather than integrating it into the starter or battery structures. This extraction simplifies the overall system by making the protection element modular and easy to install without complicating the existing components.
Solution Approach 2:
The protection block is designed as a simple, inexpensive component that can be easily replaced if damaged, rather than creating a complex permanent protection system. This approach reduces overall device complexity while maintaining reliable protection.

AI summary
Provided is a protection device for a vehicle electrical component capable of preventing damage to a predetermined electrical component due to hitting by a battery, and also capable of reducing noise/vibration. The disclosure is a protection device which protects a starter in a vehicle in which a battery and the starter are disposed to face each other with a space therebetween in an engine room of the vehicle in which components constituting a power plant or a power train are supported by a vehicle body via a mount and a bracket. The skid block serving as the protection device includes bracket attachment portions attached to a transmission attachment portion of the bracket, and a skid block main body extending upward from the bracket attachment portions and gradually away from the bracket extension portion, and having a distal end portion positioned between the battery and the starter and facing the battery.
