Innovation Solution

A crutch handle design with integrated vibration and heating capabilities, featuring a T-shaped handle body, a top case, and an upper cover, allowing easy assembly and disassembly with screw locks, and incorporating a circuit board, eccentric motor, and heating plate for user-controlled functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If functional structures (vibration motor, heating element) are added to the crutch handle, then the comfort and functionality for users with poor blood circulation is improved, but the structural complexity increases and user disassembly becomes difficult

Engineering Contradiction:
Improvefunctional versatilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The crutch handle is divided into modular components: a handle body, a top case containing the battery and motor, and an upper cover with functional elements. These segments can be assembled and disassembled independently through screw connections, maintaining functionality while reducing overall structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The top case serves multiple functions: it houses the battery for power supply, contains the vibration motor for massage function, and provides structural support. This multi-functionality reduces the need for separate components, managing complexity while enhancing versatility.

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

2Ease of operation

If functional structures are added to provide vibration and heating, then user comfort is improved, but the ease of disassembly and replacement by users deteriorates

Engineering Contradiction:
Improveuser convenienceVSAvoiduser disassembly ease
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The handle is segmented into easily separable parts connected by screw joints. Users can remove the top case and upper cover independently to access or replace functional components like the battery or motor, maintaining ease of repair while enabling added functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular design with standardized screw connections enables users to perform their own maintenance, battery replacement, or component repairs without specialized tools or expertise, promoting self-service capability.

Inventive Principle:
Principle #25Self-service

3Ease of repair

If a modular assembly structure with multiple components is used, then ease of disassembly is improved, but the device complexity increases

Engineering Contradiction:
Improvedisassembly easeVSAvoidassembly complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The handle is divided into three main segments (handle body, top case, upper cover) connected by simple screw joints. This segmentation enables easy disassembly for user maintenance while keeping each segment's internal structure relatively simple, balancing disassembly ease with overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional components (battery, motor, functional elements) are merged into the top case and upper cover assemblies. This consolidation reduces the total number of separate parts users must handle, simplifying the modular structure while maintaining disassembly ease.

Inventive Principle:
Principle #5Merging (Combining)
