Solution Overview

Problem

The watch-making industry faces challenges in integrating additional functions into watches without compromising aesthetic appeal, as existing solutions like image guides are difficult to process and prone to damage, leading to reduced image quality and increased costs.

Innovation Solution

A device using image guides mounted with suitable fastening means in openings within timepiece or watch modules, allowing flexible routing and reproduction of display information onto a desired display plane, with options for magnification and color variation, while protecting against shocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If image guides are used to reproduce display information on a different plane, then display flexibility and aesthetic appeal are improved, but image quality deteriorates due to processing difficulties and damage risks

Engineering Contradiction:
Improvedisplay flexibilityVSAvoidimage quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies beforehand cushioning by providing a recess in the support structure that receives and protects the image guide before it is installed in the display device. This recess acts as a protective cushion that prevents damage during assembly and handling, thereby maintaining image quality while still allowing the image guide to perform its function of reproducing display information on a different plane.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If additional functions are integrated into watches using timepiece modules, then functional complexity is improved, but display information positioning deteriorates due to increased distance from the dial plane

Engineering Contradiction:
Improvefunctional complexityVSAvoiddisplay information positioning
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent applies another dimension by using an image guide to transfer display information from one spatial plane (the movement plane) to another plane (the dial plane). This optical dimensionality change allows additional functions to be integrated in timepiece modules positioned away from the dial while still presenting display information at the correct visual location, thereby resolving the positioning issue caused by increased distance.

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

3Device complexity

If image guides are mounted without protective structures, then device complexity is reduced, but reliability deteriorates due to susceptibility to shocks and impacts

Engineering Contradiction:
Improvemounting structure complexityVSAvoiddamage resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies nested doll by placing the image guide within a recess of the support structure, effectively nesting the fragile image guide component inside a protective cavity. This nested arrangement provides shock and impact protection without requiring additional external protective structures, thus maintaining simplicity while improving reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)
