Visual Indication TRIZ Cases

Distinct light-limiting paths and illuminance-based thresholds improve watch hand position detection under oblique and changing light.

Overmoulded pattern blanks replace dial machining and glued appliques to prevent scratches, defects, and weak surface decoration.

Dry-plated oxide and fluoride layers with tuned refractive indexes deliver high-chroma watch colors with durable inorganic films.

Injection-molded attachment elements fix the dial blank to a support plate, enabling cleaner extraction with less damage and contamination.

Pre-calculated solar times are compressed into few bits so watches can show accurate sunrise and sunset data without GPS or heavy processing.

Low-temperature spark plasma sintering forms dense luminescent noble metal cermets while preserving pigment brightness for watch and jewelry use.

A rest plate with molded attachment elements keeps the dial ébauche secure during unmoulding, reducing surface damage and soiling in finishing.

Movable pins in a perforated plate create realistic moon phase displays in thin timepieces without bulky or fragile spherical mechanisms.

Dual gradational films on a translucent dial substrate expand pattern variety and create delicate layered color effects for more aesthetic watches.

An elastic snap-fit trim structure enables quick wearable decoration removal while preserving secure attachment and rotational tactile feedback.

A refractive-index-matched transparent coating protects ceramic trim from abrasion and chemical attack without changing its intrinsic color.

Two transmission lines let a sympathetic clock wind and step-set a watch precisely while reducing barrel wear, bias, and mechanical stress.

An elastic return member and temporary wheel decoupling simplify chronograph reset, cut force, and reduce movement complexity.

A finger-and-tooth calendar drive enables 2- or 3-step instantaneous date jumps while cutting spring losses, wear, and torque fluctuation.

A movable tooth and cam-driven finger enable multi-step date jumps with lower torque fluctuation and energy loss in mechanical calendars.

A dial wall and light-guide layer hide the watch light source at wide viewing angles while improving hand illumination uniformity and aesthetics.

Removable radial fasteners and intermediate pieces hold a rotating bezel with low axial play, easy disassembly, and improved shock resistance.

Laser-cut recessed grooves and protrusions give a thin timepiece dial high-contrast, stereoscopic hour indicators without embedded characters.

An elastically coupled two-piece heart cam lets the cam track move at the tip, avoiding quasi-static reset states and reducing wear in watches.

A ring, rod, and linkage mechanism shows the Earth-Mars viewing axis mechanically, making retrograde motion visible without electronics.

A curved shutter and plano-concave lens create realistic moon phases in a compact watch mechanism that avoids bulky rotating spheres.

A dielectric multilayer film, light-blocking layer, and luminous paint make timepiece patterns visible in both light and dark.

Specific gold, silver, or platinum alloy substrates prevent oxidation and tarnishing after enamel firing, reducing defects and inspection needs.

An elastic assembly member stabilizes watch closing force across repeated cycles while preserving precious case parts and appearance.
