Flexible Vehicle Solar Panel Attachment Against Reaction Force Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment structures for vehicle solar panels increase the risk of the solar module flying away or being damaged due to collision or movement, as they transmit reaction forces from the vehicle body to the solar module.
Innovation Solution
A flexible coupling member is used to connect the solar module to the vehicle body, comprising a panel-side attachment portion, a vehicle-body-side attachment portion, and a connection portion with flexibility, which absorbs and reduces the transmission of forces to the solar module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid bracket is used to attach the solar panel to the vehicle body, then the solar panel is securely fixed, but reaction forces from the vehicle body are transmitted to the solar module causing damage or disconnection
Solution Approach 1:
The coupling member incorporates a flexible connection portion that can bend and deform, allowing the solar panel to remain securely attached while absorbing reaction forces through elastic deformation rather than transmitting them rigidly to the solar module
Solution Approach 2:
The connection portion is designed with specific flexibility parameters (bendability, elasticity) that allow it to change its mechanical properties under load, absorbing impact forces through controlled deformation while maintaining secure attachment under normal conditions
2Device complexity
If the solar panel is directly attached to movable vehicle body parts, then the attachment structure is simple, but inertia forces during movement cause the solar module to move toward the vehicle body configuring member side
Solution Approach 1:
The flexible connection portion acts as a shock absorber during vehicle body movement, allowing controlled movement and deformation to accommodate inertia forces while preventing the solar module from moving excessively toward the vehicle body configuring member
Solution Approach 2:
The elastic connection portion is designed in advance to absorb and cushion the inertia forces that will occur during vehicle body movement, preventing direct transmission of shock forces to the solar module before damage can occur

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed attachment structure significantly reduces the likelihood of the solar module flying away or being damaged by absorbing and dissipating forces, ensuring the module remains securely attached to the vehicle body.
