DDM for Trunk Panel Tilting

Description

The trunk hinge would be detachable from the trunk panel side.

Would require an additional accessory to hold and tilt the trunk panel after detaching.

Likely requires us to add new Chassis tubes or some analysis to investigate the need for additional mounting tubes.

Trunk Prop would have to be repositioned (since it is no longer opening in the conventional direction).

The two hinges, together, would allow regular use of the trunk.

Only one side is detachable to reduce the time of operation to get the trunk panel to tilt.

The second hinge is yet an unknown mechanical mystery that would need to be designed.

Development Time

2 - Minimal change to trunk hinge; an accessory needs to be designed and manufactured for tilting feature

1 - redesign of trunk hinge from scratch, modification to trunk latch, additional analysis for chassis tubes for mounting

0 - All designs need to accommodate many facets of this option to be compatible with both conventional and sideways operation of trunk panel.
Development of the second hinge is a big unknown with little leads or resources to start on

Manufacturability

2 - Minimal change to trunk hinge. The accessory is something we add on and not require modifying the rest of the assembly.
The accessory may be an investment of time depending on the complexity pursued.

1 - the side hinge would require a very complex geometry since we do not have any convenient mounting points off of a chassis tube near the back of the car.
These side hinges would’ve been incorporated in design at the very beginning of the vehicle design. The aerobody also becomes a limiting factor for any additional chassis tubes

0 - with considering just the 2nd hinge, it sounds like a nightmare to design and ensure that it is compatible with the rest of the assembly (in terms of range of motion and physical interference).
It will also likely face the issue of trying to find mounting locations if needed.

Cable Length

2 or 1 - We would definitely need to extend the cable length to accommodate this option. Ideally the accessory could just be placed inside of the trunk so it is closer to the rest of the electrical assembly to minimize cable length.

2 - It would be ideally mounted close to its original position to minimize cable length. But there readily lacks an option to mount it close to the original position right now.

2 - would be similar to side hinges

Mechanical Complexity

3 - very minimal design change. It would just need to modify how the current trunk hinge design is mounted onto the trunk panel so that it is detachable.

1 - the side hinge itself would be complex. we would also need to do analysis to see for viable mounting points.

0 - the second hinge is a nightmare. would also need to consider analysis for chassis mounting

Amount of Disruption with existing designs

3 - only disrupts trunk hinge in a minimal way. Trunk latch, trunk hinge, and chassis design can continue operation without any changes to their design.

1 - trunk latch would have to redesign, chassis possibly redesign from analysis, trunk hinge is a complete redesign

0 - trunk hinge complete redesign. second hinge is a nightmare. trunk latch has to be redesigned. possible chassis analysis and redesign.
