Solution Overview

Problem

Existing medical fluid pumps face challenges in providing access to electronic components for service without additional openings, which increases manufacturing effort and risk of damage, or require complete disassembly for maintenance.

Innovation Solution

A medical fluid pump design with a cutout or aperture in the energy accumulator compartment allows access to electronic components without separating the upper and lower housing shells, featuring a pivotable front flap and a cutout aligned with a plug connector for easy servicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If an additional service opening is provided on the housing for accessing electronic components, then accessibility for service is improved, but the risk of foreign body ingress and manufacturing complexity increase

Engineering Contradiction:

Improveaccessibility to electronic componentsVSAvoidingress of foreign bodies and liquids

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The energy accumulator compartment opening serves multiple functions: it allows energy accumulator installation/removal and provides service access to electronic components. This multi-functional design eliminates the need for separate service openings while maintaining protection against foreign body ingress.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The energy accumulator compartment acts as an intermediary space that enables access to electronic components without creating direct openings in the housing. The compartment's opening serves as a mediated access path that can be protected while still allowing service.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the fluid pump is designed without a service opening, then protection against foreign bodies is improved, but accessibility for service deteriorates

Engineering Contradiction:

Improveprotection against foreign bodiesVSAvoidaccessibility to electronic components

Core Design Contradiction:

Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The energy accumulator compartment opening is designed to serve dual purposes: accommodating the energy accumulator and providing access to electronic components for service. This eliminates the trade-off between protection and accessibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Service access is achieved through a different spatial dimension - utilizing the vertical opening of the energy accumulator compartment rather than creating horizontal openings in the housing. This allows access without compromising the housing's protective function.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of repair

If the upper and lower housing shells are separated for servicing, then complete access to components is improved, but disassembly effort and time increase

Engineering Contradiction:

Improveaccess to interior componentsVSAvoiddisassembly and reassembly time

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The energy accumulator is extracted as a separate removable component through its dedicated opening. This extraction mechanism provides access to the interior space and electronic components without requiring separation of the housing shells, significantly reducing disassembly effort.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The service access is segmented into a specific localized opening for the energy accumulator compartment, allowing targeted access to electronic components without requiring complete disassembly of the housing assembly.

Inventive Principle:

Principle #1Segmentation

4Ease of repair

If additional service openings are added to the housing, then accessibility is improved, but manufacturing effort and costs increase

Engineering Contradiction:

Improveservice accessVSAvoidmanufacturing effort and costs

Core Design Contradiction:

Ease of repairVSEase of manufacture

Solution Approach 1:

The energy accumulator compartment opening is designed as a multi-functional feature that serves both energy accumulator access and electronic component service purposes. This eliminates the need for additional separate openings, reducing manufacturing complexity and costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The functions of energy accumulator access and electronic component service access are merged into a single opening structure. This consolidation reduces the total number of openings required, simplifying manufacturing processes and reducing associated costs.

Inventive Principle:

Principle #5Merging (Combining)
