Solution Overview

Problem

Conventional watches with cylindrical or spherical cases have limited viewing options due to opacity or flat glass covers, restricting the visibility of internal mechanisms from all angles.

Innovation Solution

A spherical watch case with gear wheels and time hands adapted to the curvature, allowing full 360-degree visibility of dynamic parts, featuring a partially or fully transparent protective cover and cone-shaped teeth on gear wheels for enhanced viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional watches use opaque or flat glass covers, then the structural integrity and simplicity are maintained, but the viewing options are limited and internal mechanisms cannot be seen from all angles

Engineering Contradiction:
Improvestructural integrityVSAvoidviewing options
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies spheroidality by using a spherical watch case instead of conventional cylindrical or flat designs. The spherical shape allows the watch to be viewed from all angles (360-degree visibility), eliminating the limitation of flat glass covers while maintaining structural integrity. The curvature of the spherical case enables comprehensive viewing of the internal mechanisms from any direction.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent transitions from two-dimensional flat displays to three-dimensional spherical geometry. By arranging gear wheels and time hands in three-dimensional space within the spherical case, the design enables viewing from all angles simultaneously, adding a spatial dimension that conventional flat watches cannot provide.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If spherical watch cases are used with transparent covers, then viewing options from all angles are enabled, but the complexity of adapting internal mechanisms to spherical geometry increases

Engineering Contradiction:
Improveviewing optionsVSAvoidmechanism adaptation
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent resolves the complexity issue by adapting the internal mechanisms to match the spherical geometry. The gear wheels are designed with curved surfaces and spherical tooth patterns that conform to the spherical case interior. This curvature adaptation allows the mechanisms to function properly within the spherical space while maintaining 360-degree visibility through transparent covers.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent employs nesting by placing multiple gear wheels at different radii within the spherical case, with each gear wheel nested concentrically around the central axis. This nested arrangement allows complex time-telling functions to be achieved within the compact spherical volume without excessive mechanical complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If gear wheels are arranged on the outer circumference of the spherical case, then comprehensive viewing from all angles is achieved, but the manufacturing precision required for spherical gear geometry increases

Engineering Contradiction:
Improveviewing accessibilityVSAvoidspherical gear geometry
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent addresses manufacturing precision by designing gear wheels with spherical tooth surfaces that mesh along curved paths. The teeth are arranged in spherical patterns rather than flat linear patterns, allowing the gear wheels to be positioned on the outer circumference of the spherical case while maintaining proper mechanical engagement. This spherical gear geometry enables viewing from all angles without requiring excessively precise manufacturing tolerances.

Inventive Principle:
Principle #14Spheroidality (Curvature)
