Soft Front Cockpit Cover for Vehicle Roof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable roof systems in vehicles, particularly those with hard tops, are cumbersome and time-consuming to open or remove, offering limited open-air experiences and posing storage challenges due to their bulkiness and weight, which complicates the transition between closed and open positions, especially in varying weather conditions.
Innovation Solution
A foldable soft panel top assembly that engages with a hard top roof, featuring lightweight components and pivot points integrated into the vehicle's door rails and linkage assemblies, allowing for quick and easy operation without leaving the vehicle, eliminating the need for complete removal and storage of panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard top is used to provide roof protection, then structural strength and weather protection are improved, but weight and bulkiness increase making removal and storage difficult
Solution Approach 1:
The roof assembly is divided into a fixed hard top portion and a separate removable soft panel top assembly. The soft panel top can be independently removed from the hard top, allowing the heavy hard top to remain installed for protection while the lighter soft panel provides open-air access when removed.
Solution Approach 2:
The soft panel top is constructed from flexible soft material rather than rigid hard material, significantly reducing weight and bulkiness. This flexible construction maintains sufficient strength for weather protection while being easy to remove and store.
2Adaptability or versatility
If the entire hard top is removed to provide open-air feel, then open-air experience is improved, but storage difficulty and handling complexity increase
Solution Approach 1:
The roof system is segmented into a permanent hard top portion and a removable soft panel top. Only the lightweight soft panel needs to be removed for open-air experience, not the entire heavy hard top assembly, making removal and storage much easier.
Solution Approach 2:
The soft panel top is extracted as a separate removable component from the hard top structure. This allows the soft panel to be independently removed and stored when open-air experience is desired, while the hard top remains installed.
3Reliability
If multiple knobs and latches are used to secure front top panels, then sealing and structural integrity are improved, but operation time and complexity increase
Solution Approach 1:
The complex multi-knob and multi-latch securing system is replaced by extracting the securing mechanism to a simpler single-latch system. The soft panel top assembly includes a single latch that secures the entire assembly to the hard top, significantly reducing operation time while maintaining sealing integrity.

AI summary
A soft panel top assembly for a vehicle in sealing engagement with a hard top portion of a roof. The soft panel top assembly has a fixed portion attached to the vehicle and a lightweight pivotal portion that folds back to provide the occupant a quick and easy open air effect. Two door rails of the soft panel top assembly are connected to the vehicle. Two side rail linkage assemblies are attached to header, which is secured to a windshield frame when in a closed position, and are connected at pivot points created with a bracket attached to the door rails to allow the pivotal portion to pivot to an open position. The soft panel top assembly includes a rear header that is lightweight and engages with the existing seal of the hard top roof portion to provide a weatherproof seal.
