Solution Overview

Problem

Existing electronic equipment with tactile transmission techniques for touch panels faces challenges in ensuring both dustproof and waterproof performance while effectively transmitting tactile senses to users.

Innovation Solution

The design incorporates a detecting unit, a vibrating body, a first housing with a base and frame body, an operation unit, and a flexible portion that surrounds the detecting unit, allowing for flexural vibration and adequate tactile sense transmission while maintaining dustproof and waterproof performance through a sealed structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sealed structure is implemented to ensure dustproof and waterproof performance, then reliability is improved, but the flexibility needed for tactile transmission is restricted

Engineering Contradiction:
Improvedustproof and waterproof performanceVSAvoidflexibility for tactile transmission
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a flexible membrane structure that acts as both a seal and a tactile transmission medium. This thin film allows vibrational movements to pass through while maintaining the sealed environment, thus resolving the contradiction between sealing reliability and tactile flexibility.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The flexible membrane serves multiple functions simultaneously: it provides dustproof and waterproof sealing while also enabling tactile sensation transmission. This multi-functionality approach allows a single component to address both requirements without compromising either.

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

2Ease of operation

If the operation unit is positioned to cover the detecting unit, then ease of operation is improved, but the transmission of tactile senses is restricted

Engineering Contradiction:
Improveoperation unit coverageVSAvoidtactile sense transmission
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The operation unit is constructed with a flexible membrane that can deform in response to vibrations from the detecting unit. This flexibility allows the operation unit to both cover the detecting unit for ease of operation and transmit tactile sensations effectively.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The operation unit is designed to be dynamically responsive, allowing it to move and deform with the vibrations generated by the detecting unit. This dynamic behavior enables both operational coverage and tactile transmission without restriction.

Inventive Principle:
Principle #15Dynamics
