Business Context
Drivers require adequate visibility to understand the surrounding environment and operate the vehicle safely and confidently. Large glass areas and thin structural pillars can improve direct visibility, but they may create challenges involving body stiffness, rollover performance, crash load paths, thermal loads, acoustic behavior, and aerodynamic design. Increasing pillar dimensions or reducing glazing can improve structural performance but create larger visual obstructions.
Automotive TRIZ Resolution
Rather than relying exclusively on direct line-of-sight visibility, Automotive TRIZ combines physical and informational resources. Structural geometry and high-performance materials can reduce obstruction where direct visibility is most valuable, while cameras, displays, and other sensing systems can provide information in regions where structural requirements prevent complete transparency. The objective is to preserve reliable environmental awareness without weakening necessary structural functions.
Applicable TRIZ Principles
Principle 3 – Local Quality optimizes pillar geometry and material properties according to local structural and visibility requirements.
Principle 24 – Intermediary uses sensing and display systems to transmit information from obstructed regions to the driver.
Principle 28 – Mechanics Substitution supplements direct optical visibility with electronic sensing where physical transparency is constrained.
Expected Outcome
Improved driver environmental awareness
Maintained structural performance
Reduced critical blind areas
Greater freedom in aerodynamic and body design
Decision Indicators
Early indicators that this contradiction is limiting vehicle design include:
Structural pillar requirements create significant driver blind zones.
Visibility improvements repeatedly conflict with crash or stiffness requirements.
Exterior design changes reduce direct sightlines around the vehicle.
Drivers depend heavily on head movement to compensate for fixed obstructions.
Increasing glass area creates significant structural or thermal penalties.
Monitoring these indicators helps identify when visibility should be treated as an information function rather than solely as a geometric requirement.
