Solution Overview

Problem

Existing electronic devices with input devices that require holes in protective cover glass face issues with sealing contaminants, increased size, and aesthetically undesirable gaps, which compromise both functionality and appearance.

Innovation Solution

A seamless protective cover glass that moves in response to user input, detected by a cover glass movement detector, generates control signals for the device's operation without the need for physical holes, using mechanisms like hinges, elastic connectors, or flexible materials to provide a seamless and sealed interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If input devices require holes in protective cover glass, then user input can be received, but sealing effectiveness deteriorates and contaminants can enter

Engineering Contradiction:
Improveuser input capabilityVSAvoidsealing effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the input function from the physical hole structure and relocates it to the movement detection system. The cover glass itself becomes the input mechanism through its movement, eliminating the need for holes while maintaining user input capability and preserving sealing integrity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical hole-based button system with an optical/electrical detection system. Instead of physical buttons requiring holes, the system uses sensors to detect cover glass movement, substituting mechanical interaction with sensor-based detection to maintain both input functionality and sealing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If holes are made in protective cover glass for input devices, then user input is enabled, but aesthetic appearance deteriorates due to gaps and breaks

Engineering Contradiction:
Improveinput device functionalityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The patent merges the input function with the protective cover glass itself. By making the cover glass movable and detecting its movement, the system combines protection and input functionality into a single seamless component, eliminating gaps and breaks while maintaining both aesthetic appearance and input capability.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If sealing elements are added to prevent contaminants, then protection is improved, but device complexity increases and size increases

Engineering Contradiction:
Improvecontaminant protectionVSAvoidsealing structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the need for separate sealing elements by making the cover glass itself the sealing barrier. The movable cover glass maintains a sealed interface with the housing through its movement mechanism, removing the need for additional sealing components and reducing overall device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electronic device with seamless protective cover glass is disclosed. In the described embodiments, the cover glass is coupled to the housing such that the cover glass or portions of the cover glass move with respect to the housing. This movement can be used as an interface for receiving user inputs that can be used to provide control signals to the electronic device.
