Solution Overview

Problem

Existing remote control systems for medical equipment often require operators to hold the control apparatus in specific positions, leading to increased burden and difficulty in maintaining desired postures.

Innovation Solution

A remote control apparatus with a movable operation handle and armrest, supported by a mechanism that transitions between two height positions, allowing operators to switch between standing and sitting postures while reducing physical strain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operator holds the control apparatus in a fixed position, then the control apparatus can be operated, but the operator experiences increased physical burden and difficulty in maintaining desired postures

Engineering Contradiction:

Improveoperator comfortVSAvoidphysical burden on operator

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The supporting mechanism enables dynamic adjustment of the operation handle's height position between first and second modes, allowing the operator to change posture during operation. This dynamic positioning resolves the contradiction by eliminating the need for the operator to maintain a fixed posture, thereby reducing physical burden while preserving operational capability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the height position parameter of the operation handle between two distinct modes (first height position and second height position). This parameter change allows the operator to switch between standing and sitting postures, resolving the contradiction between maintaining operational control and reducing physical burden

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the control apparatus is designed for a single operating position, then the structure is simple, but the operator cannot take desired postures

Engineering Contradiction:

Improveposture flexibilityVSAvoidsupporting mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The supporting mechanism incorporates dynamic positioning capability with two distinct operational modes (first and second height positions). This dynamic design provides posture flexibility without excessive complexity by offering discrete, predefined positions rather than continuous adjustment, resolving the contradiction between adaptability and device complexity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The supporting mechanism serves multiple functions: it supports the operation handle, enables posture switching between standing and sitting positions, and maintains operational control. This multi-functionality achieves posture flexibility while managing device complexity through integrated design

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The control apparatus (100) includes an operation handle (1), an armrest (5), and a supporting mechanism (9) supporting the operation handle (1) and the armrest (5). The supporting mechanism (9) is configured to be transitionable between a first mode in which the operation handle (1) is hold to be positioned at a first height position (H1) which is 85 cm or more above a floor surface and a second mode in which the operation handle (1) is hold to be positioned at a second height position (H2) which is 48 cm or more below the first height position (H1).
