Solution Overview

Problem

Conventional emergency stop button mounting methods are prone to accidental activation and require complex disassembly, with welding being inconvenient and time-consuming.

Innovation Solution

A detachable emergency stop button assembly featuring a mounting base, fastener, and protective cover, allowing for easy installation and removal from a mounting plate while preventing accidental activation through a protective cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the emergency stop button is mounted directly in the mounting hole through nuts, then the assembly is simple, but the button is apt to be accidentally touched

Engineering Contradiction:
Improveassembly simplicityVSAvoidprotection against accidental activation
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The mounting structure is divided into separate components: a mounting base with accommodating groove, a fastener, and the emergency stop button. The mounting base provides protection while the fastener secures the assembly, resolving the contradiction between simplicity and protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting base acts as an intermediary component between the mounting hole and the emergency stop button. It provides the accommodating groove that protects the button while maintaining easy assembly through the fastener mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the emergency stop button is arranged in a mounting base which is welded to the mounting hole, then the button is protected from accidental touch, but the mounting method requires a large amount of work and is inconvenient to disassemble

Engineering Contradiction:
Improveprotection against accidental activationVSAvoiddisassembly convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The welding process is replaced with a mechanical fastening system using a fastener that threads onto the mounting base. This substitution maintains the protective function while enabling easy assembly and disassembly without welding equipment.

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

Solution Approach 2:

The connection method changes from permanent welding to reversible threading. The fastener can be rotated to change its position from engaged to disengaged, allowing the mounting state to be changed easily while maintaining protection during operation.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If a protective cover is added to cover the groove opening, then accidental activation is prevented, but the device complexity increases

Engineering Contradiction:
Improveprotection against accidental activationVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protective cover is merged with the mounting base structure. The cover forms an integrated part of the mounting base, reducing the need for separate protective components while maintaining protection against accidental activation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mounting base serves multiple functions: it provides the accommodating groove for the button, acts as a protective structure, and includes the threaded portion for fastening. This multi-functionality reduces overall device complexity while maintaining protection.

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