Solution Overview

Problem

Existing timepieces lack efficient methods for securely attaching different components, such as solar panels and magnetic shield plates, to a shared main plate, leading to potential wobbling and instability during assembly.

Innovation Solution

The use of a main plate with distinct markers indicating adhesion positions for different components, allowing for precise attachment of sheet-like components like solar panels and magnetic shield plates using double-sided adhesive tape, ensuring secure fixation and preventing wobbling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single main plate is used for multiple timepiece models, then production costs are reduced and manufacturing efficiency is improved, but it becomes difficult to securely attach different components (solar panels, magnetic shield plates) with different adhesion requirements

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidattachment stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The adhesion areas on the main plate are segmented into multiple distinct regions, each marked with different markers indicating specific adhesion positions for different components. This segmentation allows the same main plate to accommodate different attachment configurations for solar panels, magnetic shield plates, and other components without compromising attachment stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the main plate are assigned different local qualities through the marker system. Each marker indicates a specific adhesion position optimized for particular components, allowing the main plate to provide component-specific attachment characteristics while maintaining overall structural uniformity across different timepiece models.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If adhesion positions are not precisely marked on the main plate, then the assembly process becomes simpler, but components may wobble or become unstable during assembly and operation

Engineering Contradiction:
Improveassembly simplicityVSAvoidcomponent stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The main plate is pre-marked with multiple adhesion position markers before the assembly process begins. These markers indicate precise locations for attaching different components, eliminating the need for complex measurement or positioning operations during assembly while ensuring stable and accurate component placement.

Inventive Principle:
Principle #10Preliminary action

AI summary

A module includes a plate and a sheet-like component. The sheet-like component is a first sheet-like component or a second sheet-like component and is fixed to the plate by an adhesive. The plate has a first marker and a second marker. The first marker indicates an adhesion position of a first adhesive for the first sheet-like component to be fixed to the plate. The second marker indicates an adhesion position of a second adhesive for the second sheet-like component to be fixed to the plate.
