Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hybrid or electric vehicles, the existing shutter designs that reduce noise by closing openings for mechanical gearbox cables prevent the addition of new conductive cables, complicating access to the tunnel between the longitudinal protruding and thermal screen, and occupy all holes in the front apron, limiting the mounting of additional batteries and increasing noise levels.
Innovation Solution
A method for a modular vehicle platform with a reserved opening in the longitudinal projection, using a guide tool and shutter with a specific shape to facilitate the mounting of a conductive cable connecting internal and external batteries, allowing the cable to pass through the tunnel while reducing noise and increasing available space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shutter is used to close the opening for mechanical gearbox cables, then noise reduction is achieved, but the addition of new conductive cables is prevented
Solution Approach 1:
The shutter is segmented to include a dedicated cable passage that allows conductive cables to pass through while maintaining the noise-blocking function. This segmentation enables the shutter to simultaneously achieve noise reduction and cable routing capability without compromising either function.
Solution Approach 2:
The shutter is designed with multi-functionality, serving both as a noise-blocking element and as a cable routing structure. The integrated cable passage within the shutter allows it to fulfill dual purposes: reducing noise transmission while enabling the passage of conductive cables between batteries.
2Object-affected harmful factors
If the opening is closed by a shutter, then noise transmission is reduced, but access to the tunnel becomes complicated
Solution Approach 1:
The cable passage is preliminarily integrated into the shutter structure during manufacturing, so that the path for cable access is pre-established. This preliminary action eliminates the need for complex post-assembly modifications to access the tunnel, maintaining ease of operation while achieving noise reduction.
3Stability of the object's composition
If all holes in the front apron are occupied by existing cables, then the structural integrity is maintained, but additional battery mounting is limited
Solution Approach 1:
Instead of adding cables through the front apron holes (two-dimensional constraint), the solution uses the tunnel space (three-dimensional space) behind the shutter. This dimensional change allows cable routing without compromising the front apron's structural integrity or requiring additional holes.
4Ease of manufacture
If a conventional shutter design is used, then manufacturing is simplified, but cable routing through the structured surface is prevented
Solution Approach 1:
The cable routing function is merged with the shutter structure itself. The shutter incorporates an integrated cable passage that combines the noise-blocking function with the cable routing function, allowing conventional manufacturing methods to be used while achieving both simplicity and cable routing capability.
