HUD Display Assembly Hooks for Wiring Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of heads-up-displays in vehicles is time-consuming and costly due to the need for assembly workers to manually hold and connect multiple components, making delicate wiring connections while trying to manage the display module and circuit board with one hand.
Innovation Solution
A heads-up-display assembly design that includes a display module with retention members or hooks, allowing the circuit board to be removably retained and preventing it from hanging freely, thus enabling easier installation without requiring the assembly worker to hold it manually, allowing hands to focus on connecting wires and other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If assembly workers manually hold the display module and circuit board with one hand while making wiring connections with the other hand, then wiring connections can be made, but assembly time increases and productivity decreases
Solution Approach 1:
The circuit board is equipped with retention members (hooks) that are pre-positioned to engage with corresponding retention features on the display module housing. This preliminary arrangement allows the circuit board to be automatically held in place during assembly, freeing the worker's hands for wiring connections without requiring manual holding.
2Ease of operation
If assembly workers manually hold the circuit board with one hand, then the circuit board can be positioned, but the worker's hands are occupied and cannot focus on wire connections
Solution Approach 1:
The retention hooks on the circuit board automatically engage with the display module housing to hold the circuit board in place. This self-retaining mechanism eliminates the need for workers to manually hold the circuit board, allowing their hands to be freed for other assembly tasks such as wiring connections.
3Ease of manufacture
If the circuit board is allowed to hang freely from the display module by a wire, then the circuit board can be easily attached, but the circuit board interferes with wire connections and assembly operations
Solution Approach 1:
The harmful effect of the circuit board hanging freely and interfering with wire connections is eliminated by introducing retention hooks that securely hold the circuit board in a fixed position. This extraction of the hanging state removes the interference problem while maintaining easy attachment through the same retention mechanism.

AI summary
A heads-up-display assembly includes a display module and a circuit board. The display module is configured to display an image on a display surface, remote to the display module. The display module includes a housing, a visual display, and one or more retention members. The circuit board controls the visual display and is coupled to the display module by a first wire. The circuit board is movable between a first configuration in which the circuit board is free to hang from the display module by the first wire, and a second configuration in which the circuit board is removably retained to the housing by the one or more retention members and not free to hang by the first wire.
