Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of motor units in vehicles, particularly in confined spaces like vehicle doors, faces challenges in efficiently feeding electrical energy and signals to plug-in modules due to spatial constraints.
Innovation Solution
A plug-in module design featuring a carrier element with angled through-recesses allows for angled electrical attachment, enabling easier adaptation to vehicle door spaces and stable insertion, along with a method involving injection molding for cost-effective production, where contact pins are pressed into recesses for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical contacts are fed to the plug-in module in the mounting direction, then the electrical connection is simple and direct, but the spatial requirements cannot be met in confined vehicle door spaces
Solution Approach 1:
The patent applies dimensionality change by orienting the through-recesses at an angle different from the mounting direction. The contact pins are inserted through recesses that are angled relative to the plug-in direction, allowing electrical connections to be established in a different spatial dimension than the mechanical insertion direction, thereby reducing the required space in the mounting direction.
2Ease of manufacture
If contact pins are pressed into through-recesses for fixation, then the assembly is simple and cost-effective, but the through-recesses must be precisely positioned
Solution Approach 1:
The pressing method utilizes self-service principles where the contact pins are inserted and fixed into the through-recesses in a single operation. The through-recesses are designed with specific geometries that guide the contact pins during insertion, and the pressing action simultaneously achieves both positioning and fixation, eliminating the need for separate positioning and securing steps.
3Adaptability or versatility
If the plug-in module is adapted to angled spaces in vehicle doors, then the adaptability improves, but the structural complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the orientation of through-recesses from the overall plug-in module structure. The carrier element maintains a simple linear structure for insertion, while the attachment body locally features angled through-recesses only where needed for electrical connection. This allows the module to adapt to angled spaces without requiring the entire structure to be complex or angled.

AI summary
A withdrawable module for a motor unit, in particular for an adjustment motor of a motor vehicle, is disclosed. The withdrawable module has a plug for insertion into a housing of the motor unit, the plug having a carrier element having a carrier-element-side axis, the carrier element including electrical plug elements for engaging with a corresponding plug-type connector of the motor unit. The withdrawable module has a connection body connected to the plug comprising a multiplicity of through-cutouts, which reach from a first side face to an opposite second side face in order to receive electrical contact pins therein. The multiplicity of electrical contact pins which are plugged from the first side face through the connection body are compressed in order to be fixed in the through-cutouts. In this case, the axis of the through-cutouts has a predetermined angle of less than 180 DEG with respect to the fitting direction.
