Vehicle Loading Surface Pivot Support for Heavy Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle loading surface systems are either not adjustable, leading to reduced luggage compartment volume or are prone to damage under heavy loads due to torque-induced splaying or destruction, making them unsuitable for carrying heavy loads, especially in bumpy conditions.
Innovation Solution
A device with a movably configured loading surface that can be raised or lowered, supported by pivot axes oriented perpendicularly to the loading surface, utilizing a torsional spring for automatic pivoting and a locking mechanism to secure the support means, allowing for one-handed operation and increased loading space volume without risking damage from torque.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the loading surface is lowered to increase loading space volume, then the loading space volume is improved, but the loading surface cannot be supported in the raised position
Solution Approach 1:
The support means is designed to be movable between a support position (where it supports the loading surface) and a stowed position (where it does not protrude into the loading space). This dynamic configuration allows the loading surface to be adjusted between raised and lowered states while maintaining structural reliability when needed.
Solution Approach 2:
The support function is separated from the loading surface structure itself, with dedicated support means (brackets with support surfaces) that can be independently positioned. This segmentation allows the support function to be activated only when the loading surface is in the raised position, avoiding interference with loading space volume when lowered.
2Ease of operation
If brackets are folded down to support the loading surface, then the loading surface can be raised, but heavy loads cause splaying or destruction of the bracket
Solution Approach 1:
The support means is designed with pre-engineered structural features (such as reinforced bracket designs and optimized geometry) that counteract the splaying forces before they can cause damage. The bracket structure incorporates strength enhancements that prevent deformation under heavy loads while maintaining the folding mechanism for adjustability.
Solution Approach 2:
The support means may utilize composite material construction or reinforced material selection that combines the necessary flexibility for folding operation with the strength required to withstand heavy loads. This allows the bracket to be both movable and durable under stress.
3Device complexity
If the loading surface is made fixed and flush with the opening edge, then structural simplicity is improved, but the loading space volume is reduced
Solution Approach 1:
The loading surface is designed to be movable rather than fixed, allowing it to be positioned in either a raised state (for maximum loading space volume) or a lowered state (flush with the opening edge). This dynamic configuration eliminates the need to choose between structural simplicity and volume optimization, as the system can adapt to different operational requirements.
