Solution Overview

Problem

Existing methods for preventing hand clamping during the reset process of movable components in electronic equipment, such as air conditioners, are costly and require complex structures and sensor installations, leading to high application costs and potential errors.

Innovation Solution

A method involving controlling a movable component to move a first preset distance in one direction, then a second preset distance in the opposite direction, and finally to the reset position, with optional pauses and photoelectric detection for safety, reducing the need for complex sensors and structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If photoelectric sensors and complex detection structures are installed to detect hand clamping, then safety is improved, but device complexity and application cost increase

Engineering Contradiction:
ImprovesafetyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The movable component itself performs the safety function by automatically reversing direction when an obstacle is detected during reset, eliminating the need for external detection sensors. The component serves both its primary function and safety function, reducing system complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent removes complex photoelectric detection structures and external sensors from the system, retaining only the essential reset function with integrated obstacle detection capability that uses the component's own movement and positioning to ensure safety.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If photoelectric sensors and complex detection structures are installed to detect hand clamping, then safety is improved, but application cost increases

Engineering Contradiction:
ImprovesafetyVSAvoidapplication cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The movable component integrates obstacle detection and safety reversal functionality into its own control logic, eliminating the need for expensive external photoelectric sensors and complex detection systems, thereby reducing application cost while maintaining safety.

Inventive Principle:
Principle #25Self-service

3Productivity

If the movable component moves directly to the reset position without reverse movement, then productivity is improved, but hand clamping risk increases

Engineering Contradiction:
Improvereset speedVSAvoidhand clamping risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs a preliminary reverse movement before completing the reset to the final position. This preliminary action creates temporal separation that allows users to withdraw hands if clamped, preventing harm while still achieving the reset function efficiently.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The reset process incorporates periodic direction changes (forward movement followed by reverse movement) rather than continuous unidirectional motion. This periodic action pattern ensures safety by creating intervals where the component reverses, allowing users to escape potential clamping while maintaining overall productivity.

Inventive Principle:
Principle #19Periodic action
