Solution Overview

Problem

Conventional bezels have a fixed size, limiting their application to specific object sizes and reducing their versatility, as they cannot be easily adapted to objects of different dimensions.

Innovation Solution

A bezel member with a retractable mechanism, equipped with detecting and control mechanisms that allow for real-time adjustment of its size by extending or retracting based on the presence and position of neighboring objects, using sensors like optical, infrared, or ultrasonic detectors to generate signals for controlling the extension and retraction process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size bezel structure is used, then the manufacturing and installation process is simple, but the adaptability to different object sizes is poor

Engineering Contradiction:
Improveadaptability to different object sizesVSAvoidbezel structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bezel structure transitions from a fixed static design to a dynamic adjustable one. The retractable part can extend and retract along the longitudinal direction, allowing the bezel to adapt to different object sizes. This dynamic capability resolves the contradiction by enabling size adaptation while maintaining a relatively simple overall structure through controlled movement rather than multiple fixed components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bezel is divided into a fixed part and a retractable part that can move independently. This segmentation allows the retractable portion to adjust its length while the fixed part maintains structural stability. The division enables adaptability to different sizes without requiring complete structural redesign, thus resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a retractable mechanism with detecting and control systems is added, then the adaptability to different object sizes is improved, but the device complexity increases

Engineering Contradiction:
Improveautomatic size adaptationVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bezel system performs self-measurement and self-adjustment through the detecting mechanism that automatically detects object dimensions and triggers appropriate retraction or extension of the retractable part. This self-service capability eliminates the need for manual measurement and adjustment, achieving automatic adaptation while keeping the control system relatively simple through autonomous operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detecting mechanism provides feedback about object size to the control system, which then adjusts the retractable part's position accordingly. This feedback loop enables automatic adaptation to different object sizes. The principle resolves the contradiction by using minimal feedback-based control rather than complex predictive or manual control systems.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If multiple detectors are used for precise position detection, then the measurement precision is improved, but the device complexity and cost increase

Engineering Contradiction:
Improveneighboring object position detection accuracyVSAvoiddetection mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detecting mechanism is designed to perform multiple functions: detecting neighboring objects, determining their positions, and triggering appropriate retraction or extension actions. By making the detection system multi-functional, the patent achieves precise measurement capabilities without requiring separate specialized detectors for each function, thus resolving the contradiction between precision and complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detection and control functions are merged into an integrated system where the detecting mechanism directly interfaces with the retractable part control. This merging eliminates the need for separate complex control systems and intermediate components, achieving precise position detection while maintaining relatively simple overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)
