Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a camera module is mounted to a camera mounting bracket using conventional methods, then the mounting process is simple, but the security and reliability of the attachment is insufficient

Engineering Contradiction:

Improvemounting reliabilityVSAvoidmounting structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mounting structure is divided into separate functional components: holding sections (106, 107) that protrude from the housing, holding rails (108, 109) that extend between rear and front portions, hook-shaped receiving portions (206a, 206b, 207a, 207b) in the bracket, and resilient members (209, 210). This segmentation allows each component to perform its specific function while collectively providing secure attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holding sections and holding rails are integrated into the housing structure, with the holding sections protruding from the housing and the holding rails extending between portions of the housing. The resilient members are received by the hook-shaped receiving portions, creating a nested arrangement where components fit together to form a compact yet robust mounting system.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If holding sections with inner and outer parts are used, then secure locking is achieved, but the manufacturing complexity increases

Engineering Contradiction:

Improvelocking securityVSAvoidholding section manufacturing

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Each holding section is divided into an inner part and an outer part with different cross-section areas. The inner part has a smaller cross-section area than the outer part, creating a stepped configuration that provides secure locking when engaged with the hook-shaped receiving portions. This segmentation allows the holding sections to be manufactured as integrated parts of the housing using conventional molding techniques.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If guiding rails and guiding portions are added, then alignment precision is improved, but the device complexity increases

Engineering Contradiction:

Improvealignment precisionVSAvoidmounting structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The guiding rails (112, 113) extend between the rear and front portions of the housing, integrating the alignment function into the existing housing structure. The guiding portions (211, 212) in the mounting bracket correspond to these rails, creating a matched pairing that guides the camera module into proper alignment during installation. This merging of guiding functions into the primary mounting structure avoids adding separate, complex alignment mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If resilient members are used for retention, then the mounting reliability is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improveretention reliabilityVSAvoidmounting bracket manufacturing

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The resilient members (209, 210) are made from elastic material that can deform and recover. When the holding sections are inserted into the hook-shaped receiving portions, the resilient members deform to accommodate the holding sections and then exert retaining forces to secure them in place. This use of material parameter changes (elasticity) provides reliable retention without requiring complex mechanical retention mechanisms.

Inventive Principle:

Principle #35Parameter changes
