Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing fastening systems are used for telematic modules, then the module can be secured to the vehicle roof, but the assembly process becomes complex and time-consuming

Engineering Contradiction:

Improveassembly speedVSAvoidfastening system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The fastening system is divided into separate functional elements: a support block with referencing formations for positioning, a connector system with male/female parts for electrical connection, and a blocking member with spring mechanism for securing. This segmentation allows each component to be optimized independently and simplifies the overall assembly process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spring-activated blocking member automatically engages with the support block to secure the telematic module without requiring additional fastening operations. The referencing formations automatically guide alignment during insertion, eliminating the need for manual positioning adjustments and reducing assembly complexity.

Inventive Principle:

Principle #25Self-service

2Loss of time

If existing fastening systems are used for telematic modules, then the module can be secured to the vehicle roof, but the installation time increases

Engineering Contradiction:

Improveinstallation timeVSAvoidconnection ease

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The support block is pre-equipped with referencing formations that define the correct insertion position and orientation before the connector is engaged. The blocking member with spring is pre-positioned to automatically engage during insertion, eliminating the need for separate alignment and securing operations that would increase installation time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The spring-activated blocking member replaces complex mechanical fastening systems with a simple elastic engagement mechanism. The spring provides automatic tension and engagement force, eliminating the need for manual tightening or multiple fastening steps, thereby reducing installation time while maintaining ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If a simple connector system is used, then the connection process becomes fast and easy, but the securing reliability may be compromised

Engineering Contradiction:

Improveconnection speedVSAvoidfastening reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system merges the positioning function (referencing formations), electrical connection function (male/female connectors), and mechanical securing function (blocking member with spring) into a single integrated fastening operation. This combination ensures that alignment, connection, and securing all occur simultaneously, maintaining both speed and reliability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The spring mechanism provides tactile and audible feedback when the blocking member engages with the support block, confirming that the telematic module is properly secured. This feedback mechanism ensures reliability by allowing operators to verify successful installation without requiring additional inspection steps, thus maintaining connection speed.

Inventive Principle:

Principle #23Feedback
