Vehicle Protector Structure for Wireless Power Receiving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs lack effective protection for non-contact power receiving devices from obstacles on the road surface, particularly when traveling forward or backward, which can lead to damage and disruption of power transmission and reception.
Innovation Solution
A vehicle configuration featuring a covered member with a front and rear protecting member positioned below the lowest portion of the covered member, utilizing a supporting frame with front and rear protecting portions to prevent contact with obstacles, and a bracket for impact absorption, ensuring the non-contact electric element remains functional while minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the non-contact electric element is disposed on the lower surface of the vehicle body for wireless power transmission and reception, then the ease of operation and functionality are improved, but the vulnerability to obstacles on the road surface increases
Solution Approach 1:
The covered member acts as an intermediary protective layer between the non-contact electric element and the road surface obstacles. This covering structure prevents direct contact while allowing the electric element to maintain its functional position on the lower surface of the vehicle body for wireless power transmission and reception.
Solution Approach 2:
The front and rear protecting members extend below the covered member to provide beforehand cushioning protection. These protecting members are positioned to contact obstacles first, absorbing impact forces before they can reach the covered member and the non-contact electric element, thus preventing damage in advance.
2Reliability
If protecting members are added to prevent contact with obstacles, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The covered member and front/rear protecting members are merged into an integrated protective assembly. This unified structure provides both coverage and impact protection simultaneously, reducing the number of separate components needed while maintaining comprehensive protection for the non-contact electric element.
Solution Approach 2:
The protecting members serve multiple functions: they act as impact absorbers, structural supports for the covered member, and protective barriers against obstacles. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity while improving reliability.

AI summary
A vehicle includes a cover, a front protector, and a rear protector. The cover has a cover lowest portion projecting from the bottom of the vehicle body toward an outside of the vehicle by a first distance. The front protector is provided on a front side of the cover in a front-rear direction. The front protector has a front protector lowest portion projecting from the bottom of the vehicle body toward the outside of the vehicle a second distance longer than the first distance. The rear protector is provided on a rear side of the cover in the front-rear direction. The cover is provided between the front protector and the rear protector in the front-rear direction. The rear protector has a rear protector lowest portion projecting from the bottom toward the outside of the vehicle by a third distance longer than the first distance.
