Asymmetric Decorative Elements for Automotive Trim Gap Management

The patent applies asymmetry by designing the first and second decorative elements with non-symmetric thickness distributions. Specifically, the first element has a first thickness at its first end portion that differs from its second thickness at its second end portion, while the second element has corresponding thickness variations. This asymmetric design allows the elements to be positioned at an angle to each other, creating a tapered gap that is visually less noticeable than a uniform gap of the same width, thereby maintaining quality appearance while accommodating manufacturing tolerances.

The patent transitions from a two-dimensional planar arrangement to a three-dimensional angular arrangement. By positioning the first and second elements at an angle rather than perfectly adjacent in a single plane, the gap between them becomes a three-dimensional feature with varying width. This dimensional change allows the gap to be oriented such that it is less visually prominent, effectively hiding the manufacturing tolerances while maintaining aesthetic quality.

The asymmetric thickness design allows standard manufacturing tolerances to produce visually acceptable results. By creating elements with varying thicknesses that taper toward the junction, the patent ensures that even with typical manufacturing variations, the resulting gap maintains a consistent visual appearance that does not reveal imprecision, eliminating the need for costly high-precision manufacturing.

The patent converts the harmful effect of manufacturing gaps into a beneficial aesthetic feature. Rather than attempting to eliminate the gap through expensive precision manufacturing, the design embraces the gap as an intentional design element, using asymmetric thicknesses to create a tapered appearance that is visually pleasing. This approach transforms what was previously a defect into a feature, reducing manufacturing costs while maintaining or even enhancing visual quality.

The asymmetric thickness design makes the visual appearance insensitive to positioning variations. Because the elements have varying thicknesses that create a tapered gap profile, small deviations in positioning do not create noticeable changes in the visual appearance. The gap maintains a consistent aesthetic quality even when elements are not positioned with perfect precision, effectively decoupling visual quality from measurement precision requirements.

The patent changes the geometric parameters of the elements, specifically the thickness distribution along their lengths. By implementing non-uniform thickness profiles where the thickness varies along the length of each element, the design creates a gap that is visually acceptable across a range of positioning conditions. This parameter change makes the system robust against positioning variations without requiring tight tolerances.
