Solution Overview
Problem
Existing support structures for vehicle instrument panels lack efficient lateral positioning and secure fastening mechanisms, leading to potential instability and misalignment within the passenger compartment.
Innovation Solution
A support structure featuring a lateral biasing guide and end brackets that attach to both the instrument panel and vehicle body panels, utilizing a resilient finger and ramp system to guide and lock the panel into precise lateral, fore/aft, and up/down positions, ensuring secure attachment and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid support structure is used to secure the instrument panel, then stability and security are improved, but complexity of the support structure increases
Solution Approach 1:
The support bracket incorporates a resilient finger that can flex laterally to accommodate misalignment during assembly while maintaining secure attachment. This dynamic element allows the rigid support structure to adapt to minor positioning variations without requiring complex adjustment mechanisms, thereby maintaining stability while reducing overall structural complexity.
Solution Approach 2:
The resilient finger changes its physical state from a flexible, laterally movable position to a constrained position against the lateral datum surface. This parameter change enables the support structure to transition from an adaptive assembly state to a rigid secured state, providing stability without requiring a completely rigid design throughout the entire structure.
2Manufacturing precision
If precise lateral positioning is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The resilient finger automatically performs the positioning function by flexing laterally during assembly and then engaging with the lateral datum surface to constrain the instrument panel. This self-positioning mechanism eliminates the need for complex external positioning devices or adjustment mechanisms, achieving precise lateral positioning through the inherent properties of the resilient finger itself.
Solution Approach 2:
The resilient finger acts as an intermediary element between the support bracket and the instrument panel, providing a compliant interface that guides the panel into precise lateral alignment. This intermediary component simplifies the overall positioning mechanism by absorbing misalignment and guiding the panel to its correct position without requiring complex positioning devices.
3Reliability
If multiple attachment points are used to secure the instrument panel, then reliability is improved, but ease of manufacture decreases
Solution Approach 1:
The support bracket is segmented into distinct functional elements: a resilient finger for lateral positioning, a rear face for mounting to the body panel, and a support surface for the instrument panel. This segmentation allows each element to perform its specific function independently, simplifying the manufacturing and assembly process while maintaining reliable secure attachment through the coordinated action of the segmented components.

AI summary
A support structure is configured for locating an instrument panel within a passenger compartment of a vehicle. The support structure includes a support bracket and an end bracket. The support bracket is attached to a body panel of the vehicle. The support bracket includes a lateral biasing guide. The end bracket is attached to an end of the instrument panel. The end bracket has a first side. The first side abuts the lateral biasing guide of the support bracket such that the lateral biasing guide biases the instrument panel in a lateral direction until the end bracket abuts the lateral datum surface of the first body panel.
