Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compression spring and tension spring are used in the driving mechanism, then the driving function is achieved, but the structure becomes complicated

Engineering Contradiction:
Improvedriving functionVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple springs (compression springs and tension springs) into a single integrated driving mechanism. The springs are arranged in parallel and connected through a common connecting piece, merging their functions into one unified structure that reduces overall complexity while maintaining the driving capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting piece serves multiple functions: it connects multiple springs together, provides a mounting point for the slide cover, and transmits the combined force from all springs to the sliding mechanism. This multi-functional component reduces the number of separate parts needed in the system.

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

2Ease of operation

If traditional driving mechanism is used, then the slide cover can be driven, but the area occupied during spring deformation is large

Engineering Contradiction:
Improveslide cover drivingVSAvoiddeformation area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The springs are arranged in a parallel configuration on the same plane rather than stacking them vertically or arranging them in three-dimensional space. This planar arrangement reduces the deformation area in the vertical dimension while maintaining the driving function, allowing for more compact integration into the slide cover hinge structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The spring structure is designed to deform within a constrained planar space, effectively using a thin-film-like arrangement where multiple springs operate in parallel within a limited area. This allows the mechanism to maintain flexibility and driving capability while occupying minimal space.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

This invention provides the combined driving spring in the slide cover hinge of the mobile communication terminal. It comprises multiple springs in the same shape, the multiple springs are arranged and combined in turn on the same plane, with their both ends fixed; the driving spring is provided with connections on its both ends to match with the slide in the slide hinge. The shape of the spring is similar to the shape W. The driving spring provided by this invention can be directly used as a driving mechanism in the slide hinge for the mobile communication terminals, simplifying the structure of the driving mechanism. In particular, when the spring in the shape of W is employed, the spring can not only facilitate the combination connection, but also provide a greater force. Besides, when the slide cover slides, less area is occupied when the spring deforms, making it easier to arrange other parts of the mobiles device.
