EV Charger Wall Shield Panel for Cord Damage Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The extensive electrical cord used for charging electric vehicles can damage walls due to its length, as it is often wrapped around the charger and may cause discoloration or physical harm over time.
Innovation Solution
A shield with a panel, made of a material such as PVC-based foam or other materials, is mounted to the wall with a coating and fasteners, designed to receive the charger housing and protect the wall from the cord by providing a physical barrier and electrical connection.

Engineering Contradiction Analysis
1Length of moving object
If an extensive electrical cord is used for charging, then the charging distance is extended, but the wall is damaged due to cord wrapping and contact
Solution Approach 1:
A shield panel is introduced as an intermediary protective element between the electrical cord and the wall. The panel receives the charger housing and provides a protective barrier that prevents the cord from directly contacting and damaging the wall surface, while still allowing the cord to extend for charging purposes.
Solution Approach 2:
The shield panel is pre-installed on the wall before the charger is mounted. This preliminary protective measure ensures that when the charger and cord are later installed, the wall is already protected from potential cord-related damage, eliminating the need for retroactive protection.
2Object-affected harmful factors
If a shield panel is mounted on the wall to protect from cord damage, then wall protection is improved, but the device complexity increases
Solution Approach 1:
The shield panel combines multiple functions into a single integrated component: it serves as both a protective barrier for the wall and a mounting surface for the charger housing. The panel incorporates both protective and mounting features, eliminating the need for separate protective plates and mounting structures.
Solution Approach 2:
The shield panel is designed to perform multiple functions simultaneously: protecting the wall from cord damage, providing a mounting surface for the charger, and potentially serving as an aesthetic cover for the electrical outlet area. This multi-functionality reduces the need for additional components.
3Object-affected harmful factors
If the shield panel is made durable to protect the wall, then protection effectiveness is improved, but the manufacturing cost increases
Solution Approach 1:
The shield panel utilizes a thin but durable material that provides effective protection against cord-related damage while remaining cost-effective to manufacture. The material is sufficient to prevent wall damage without requiring thick, expensive materials, achieving an optimal balance between protection and manufacturing cost.

AI summary
A shield can have situated thereon a charger to charge an electrical vehicle, the shield including a panel comprising a body portion formed of a first material and a coating apparatus that is formed of a second material different than the first material, the coating apparatus being applied to at least one of the front surface and the rear surface. The shield can protect a wall to which the charger is mounted for the charging electrical. The shield can be combined with an electrical receptacle box to form a protector.
