Solution Overview
Problem
Existing methods for connecting multibrackets to vehicle frames face challenges in providing adequate feedback on correct assembly and securing the multibracket in multiple directions, particularly along the longitudinal and vertical axes.
Innovation Solution
A system and method utilizing a multibracket with a trough and spring clips that interact with pins on the vehicle frame, providing haptic feedback and securing the multibracket through axial and transverse biasing, using a pin head and spring clip interaction to ensure correct assembly and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If blind assembly is used to connect multibracket to vehicle frame, then assembly speed is improved, but assembly correctness cannot be confirmed
Solution Approach 1:
The spring clip provides tactile feedback to the assembler through its elastic deformation and engagement with the pin. When the multibracket is correctly positioned, the spring clip engages with the pin in a specific manner that provides sensory feedback, allowing the assembler to confirm correct assembly without visual inspection.
2Stability of the object's composition
If multibracket is fixed along the longitudinal axis using spring clip and pin, then displacement along x-axis is prevented, but positioning along the vertical axis is compromised
Solution Approach 1:
The connection system is segmented into distinct functional elements: the spring clip handles longitudinal positioning and provides tactile feedback, while the pin structure with its specific geometry (including the pin head and shaft portions) handles vertical positioning. This segmentation allows each element to optimize its function without interfering with the other axis.
Solution Approach 2:
The spring clip is oriented at an angle relative to the pin, creating a mechanical interaction that couples movements in different dimensions. The angular arrangement of the spring clip's engagement with the pin allows it to resist longitudinal displacement while its geometry and the pin's features work together to maintain vertical positioning precision.

AI summary
A system for connecting a multibracket to a vehicle frame is provided. The multibracket comprises a trough to be placed across the vehicle frame and at least one spring clip extending into the trough. The vehicle frame comprises at least one pin extending distally from the vehicle frame, the at least one pin extending along a pin axis, and the at least one pin comprising a pin head at a distal end thereof. The multibracket is adapted to be placed across the vehicle frame, such that the at least one pin extends into the trough to cooperate with the at least one spring clip, such that a lip on the at least one spring clip is biased against the at least one pin proximally to the pin head.
