Business Context
Modern vehicles contain increasing numbers of comfort, safety, connectivity, convenience, performance, and driver-assistance features. Additional sensors, actuators, controllers, wiring, displays, motors, structural supports, acoustic treatments, and mechanical systems can incrementally increase vehicle mass. Although each feature may contribute only a small amount individually, accumulated feature content can significantly affect energy consumption, range, vehicle dynamics, payload, and material requirements.
Automotive TRIZ Resolution
Automotive TRIZ seeks to increase functionality without increasing physical content proportionally. Existing sensors, computing resources, displays, actuators, communication networks, and structural elements can perform multiple functions where appropriate. Software can provide functionality that previously required dedicated hardware, while integrated modules can replace multiple independent components. Functional analysis should identify duplicated resources and determine whether one element can provide several useful functions without creating unacceptable common dependencies.
Applicable TRIZ Principles
Principle 5 – Merging combines related functions or components to reduce duplicated hardware.
Principle 6 – Universality enables one component or resource to perform multiple useful functions.
Principle 28 – Mechanics Substitution replaces selected physical mechanisms with electronic, software, or information-based functions where appropriate.
Expected Outcome
Increased vehicle functionality
Lower mass growth from additional features
Reduced component duplication
Improved functional integration
Decision Indicators
Early indicators that this contradiction is limiting vehicle development include:
Each new feature requires dedicated hardware.
Vehicle mass increases significantly through accumulated minor components.
Multiple systems use separate sensors for similar information.
Wiring and controller counts grow with every vehicle generation.
Feature deletion becomes necessary to achieve mass targets.
Monitoring these indicators helps identify opportunities to increase functionality through shared resources rather than additional physical content.
