Spoiler Connection Hook With Rotating Lock for Flush Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assembly methods for motor vehicle spoilers, which involve clipping and screwing, fail to adequately reduce clearances and flushes between parts, resulting in an uneven aesthetic appearance due to insufficient stress on the components to deform and align them properly.
Innovation Solution
A locking element with a cylindrical body and retaining fins that snap-fit the parts together, allowing for isostatic assembly by pressing the parts together when locked, preventing relative movement and ensuring a flush, continuous appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clips and screws are used to assemble spoiler parts, then the parts can be fixed to the tailgate, but gaps and misalignments between parts cannot be eliminated
Solution Approach 1:
The locking element transitions from an unlocked to a locked position through rotation, dynamically changing the assembly state. This rotational movement allows the locking element to engage with retaining elements and apply deformation force, transforming the static clipped assembly into a flush, aligned configuration.
Solution Approach 2:
The locking element changes the physical state of the spoiler parts by applying stress that deforms them elastically. This parameter change in shape and position of the parts eliminates gaps and achieves flushness, while the locking element itself changes position from unlocked to locked through rotation.
2Ease of manufacture
If pre-assembly by clipping is used, then assembly is simplified, but sufficient stress cannot be applied to deform components and eliminate gaps
Solution Approach 1:
The assembly process is segmented into distinct phases: initial clipping for ease of assembly, followed by locking element engagement for precision alignment. The locking element acts as a separate mechanism that applies the necessary stress to eliminate gaps without complicating the initial assembly process.
Solution Approach 2:
The clipping operation performs a preliminary assembly function, positioning the parts in approximate alignment. This preliminary action simplifies the overall process by getting parts close to final position, after which the locking element performs the precision alignment by applying deformation stress.
3Reliability
If multiple assembly elements are used, then fixation is secured, but device complexity increases
Solution Approach 1:
The locking element combines multiple functions into a single component: it prevents relative movement between parts, applies deformation stress to eliminate gaps, and secures the flush alignment. This merging reduces the number of separate assembly elements needed while maintaining assembly stability.
Solution Approach 2:
The locking element serves multiple purposes simultaneously: it acts as a mechanical lock to prevent movement, a deformation tool to close gaps, and an alignment device to ensure flushness. This multi-functionality reduces overall device complexity by consolidating several functions into one element.

AI summary
The invention relates to an assembly (10) formed by the assembly of two parts (1, 2), in particular bodywork, of a motor vehicle comprising: - a first part (1); - a second part (2), said first and second parts (1, 2) being assembled by clipping or snapping; - a locking element (4) intended to prevent any relative movement between the first and second parts (1, 2), said locking element (4) being able to move in rotation around an axis (ZZ') under the action of maneuvering means between an unlocked position, in which a relative movement between the first and second parts (1, 2) is possible, and a locked position, in which it prevents any relative movement between the first and second parts (1, 2).
