Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If stops are provided as separate components, then stopping function is achieved, but installation space requirements increase and manufacturing complexity increases

Engineering Contradiction:

Improvestopping functionVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The stop function is merged with the outer part by integrating stop elements directly into the half-shells. The stop elements are formed as integral parts of the half-shells during the molding process, eliminating the need for separate stop components and reducing overall device complexity while maintaining the stopping function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The outer part serves multiple functions: it provides structural support, enables clipping attachment via fastening elements, and incorporates stopping function through integrated stop elements. This multi-functionality reduces the number of separate components needed in the assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If stops are provided as separate components, then stopping function is achieved, but installation space requirements increase

Engineering Contradiction:

Improvestopping functionVSAvoidinstallation space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The stop elements are merged with the outer part structure, specifically formed as integral features of the half-shells. This integration eliminates the need for additional installation space that would be required for separate stop components, as the stopping function is achieved within the existing outer part geometry.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If externally mounted stops are used, then stopping function is achieved, but mounting difficulty increases and process intensity increases

Engineering Contradiction:

Improvestopping functionVSAvoidmounting ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The stop elements are merged with the outer part and formed as integral features during the molding process. This eliminates the need for separate mounting operations for stops, significantly reducing manufacturing process intensity and improving ease of manufacture.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stop elements are pre-formed as integral parts of the half-shells during the molding process, before assembly. This preliminary formation of the stop function eliminates subsequent mounting steps and reduces overall manufacturing complexity.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If additional components are provided for stops, then stopping function is achieved, but cost increases

Engineering Contradiction:

Improvestopping functionVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The stop function is merged with the outer part by forming stop elements as integral features of the half-shells. This reduces the total quantity of components in the assembly and eliminates the costs associated with manufacturing, inventory, and assembly of separate stop components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The outer part is designed to perform multiple functions including structural support, clipping attachment, and stopping function through integrated elements. This multi-functionality reduces the total number of components needed, thereby reducing material costs and assembly costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)
