Rotatable Slidable Tailgate Panel for Variable Bed Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate extension devices for vehicles are limited in that they modify the external structure and only allow for a fixed extension of the bed, failing to provide a mechanism for variable length extension and integration of extension mechanisms within the tailgate.
Innovation Solution
A tailgate design that incorporates a rotatable and slidable mechanism, where the tailgate panel can be rotated upright and further extended by sliding elongate support members out of the tailgate housing, allowing for both a fixed and variable extension of the vehicle bed length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tailgate extension devices are designed with external structural modifications, then the bed extension function is achieved, but the vehicle appearance is compromised and the extension distance is fixed
Solution Approach 1:
The tailgate panel is nested within the tailgate housing, with the panel capable of being rotated upright and extended outward. The support members are nested within the housing, allowing the panel to extend only when needed while maintaining a compact appearance when retracted, effectively hiding the extension mechanism within the tailgate structure itself
2Adaptability or versatility
If tailgate extension devices use fixed extension mechanisms, then the device complexity is reduced, but the adaptability to different loading needs is limited
Solution Approach 1:
The support members are designed to be slidable within the tailgate housing rather than fixed, allowing the tailgate panel to extend to variable distances based on loading needs. The sliding mechanism provides dynamic adjustment capability while maintaining relatively simple construction through the use of guide members and springs
3Length of stationary object
If tailgate panel is made rotatable and slidable for extension, then the bed length can be extended by fixed and variable distances, but the device complexity increases
Solution Approach 1:
The extension mechanism is segmented into distinct functional components: rotatable connection at the housing, sliding support members with guide members, and spring mechanisms. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving the dual capability of fixed and variable extension distances
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the bed of a vehicle to be extended by a predetermined height and further by a variable distance, maintaining a normal appearance and preventing load shifting during acceleration, while allowing for easier loading of items.
Implementation Method 1
sliding the upright tailgate inner panel away from the bed of the vehicle, thereby further extending the bed of the vehicle by a variable distance away from the bed of the vehicle

AI summary
A tailgate for extending the length of the bed of a vehicle, with the tailgate comprising a tailgate panel that is rotatably and slidably connected to a tailgate housing, enabling the tailgate panel to be rotated into and upright position, thereby extending the length of the bed of the vehicle by the height of the tailgate panel, and by extending the bed of the vehicle further by sliding the upright tailgate panel away from the tailgate housing.
