Reversible Cargo Lid Handle with Offset Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle cargo lid assemblies lack a compact and robust design for reversible and removable cargo lids, with existing handle mechanisms often resulting in increased thickness and reduced tactile feedback, leading to a less efficient and more cumbersome operation.
Innovation Solution
A cargo lid assembly featuring a reversible and removable cargo lid with a plunger mechanism and laterally offset tabs on side handles that rotate to move the plunger between extended and retracted positions, allowing for compact design and improved tactile feedback through resilient bumper members and spring biasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional handle mechanisms are used for reversible cargo lids, then the structure is simple, but the assembly thickness increases and tactile feedback is reduced
Solution Approach 1:
The handle tabs are positioned laterally offset from the plunger centerline, utilizing lateral spacing rather than longitudinal thickness to achieve the necessary mechanical leverage. This dimensional repositioning reduces the thickness dimension while maintaining operational effectiveness and tactile feedback through the resilient bumper members.
2Reliability
If actuators for latch mechanism are provided on both sides of closure panel, then latching reliability is improved, but device complexity increases
Solution Approach 1:
The plunger mechanism serves as a universal actuator that can be operated from either side of the cargo lid through symmetrically positioned handles. This single plunger design performs the latching function regardless of which side is accessed, eliminating the need for separate actuators on each side while maintaining latching reliability from both orientations.
3Adaptability or versatility
If cargo lid is designed to be both reversible and removable, then versatility is improved, but structural integrity becomes more difficult to maintain
Solution Approach 1:
The cargo lid assembly is segmented into distinct functional components: the removable cargo lid itself, the plunger mechanism, the resilient bumper members, and the handle assembly. This segmentation allows the lid to be easily removed and reversed while each component maintains its structural integrity through optimized design. The modular nature enables the lid to be detached without compromising the strength of individual components.

AI summary
A vehicle cargo lid assembly includes a reversible vehicle cargo lid, a plunger movably mounted to the cargo lid for movement between an extended position for latching the vehicle cargo lid in a closed position and a retracted position for unlatching the vehicle cargo lid, a first handle mounted on a first side of the cargo lid and a second handle mounted on a second, opposite side of the cargo lid. The first and second handles are arranged so that rotation of either handle moves the plunger from the extended position to the retracted position. At least one of the first handle and the second handle includes at least one tab laterally offset from a center line of the plunger that engages and moves the plunger when said at least one of the first side handle and the second side handle is rotated.
