Foldable Vehicle Hardtop Segments for Single-Operator Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle hardtop systems are difficult for a single person to assemble and remove, and they often require disassembly into segments that occupy valuable cargo space or hinder access.
Innovation Solution
A vehicle hardtop system with foldable segments connected by hinges, made from high-strength materials like metal, fiberglass, or composites, allowing easy removal and storage by a single person, with sealing gaskets to prevent environmental intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hardtop is made as a single rigid structure, then structural integrity is improved, but ease of operation deteriorates (difficult for single person to assemble and remove)
Solution Approach 1:
The hardtop is divided into multiple rigid segments (front segment, rear segment, and at least one intermediate segment) connected by latches. This segmentation allows the hardtop to be easily assembled and removed by a single person while maintaining structural integrity when installed, as each segment is rigid yet the entire structure can be quickly configured or disassembled.
2Ease of operation
If the hardtop is disassembled into segments for storage, then ease of operation is improved, but cargo space is reduced (segments occupy valuable cargo space)
Solution Approach 1:
The hardtop segments are designed to nest within one another when removed from the vehicle, with smaller segments fitting inside larger segments. This nesting configuration significantly reduces the storage volume required for the hardtop segments, preserving valuable cargo space within the vehicle while maintaining ease of removal and storage operations.
3Strength
If conventional hardtop systems are used, then structural integrity is maintained, but device complexity increases (difficult to assemble and remove)
Solution Approach 1:
The hardtop system incorporates latches that automatically engage and disengage to secure and release the segments. This self-service mechanism simplifies the assembly and removal process, allowing a single person to operate the system easily while maintaining robust structural connections when installed, thereby reducing overall device complexity.
