Solution Overview

Problem

Existing vehicle state checking devices face challenges in providing a stable and accurate measurement for both tire tread and brake disc detection, as they require different base sizes and suffer from unstable support and aesthetic issues due to external bases.

Innovation Solution

A check device with a telescopic base comprising a first and second base body and a locking mechanism, allowing the device to adapt between tire tread and brake disc detection scenarios without replacing the base, ensuring stable support and accurate measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a large base is used for tire tread detection, then the support stability is improved, but the device cannot be used for brake disc detection

Engineering Contradiction:
Improvesupport stabilityVSAvoiddetection scene compatibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The base is designed with a telescopic structure that allows it to dynamically change its size. The second base body can slide relative to the first base body, enabling the base to extend for tire tread detection (providing large support area and stability) and retract for brake disc detection (reducing size to fit through hub spokes). This dynamic adjustment resolves the contradiction between needing a large stable base and needing a compact base for different applications.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The second base body is designed to be accommodated within the first base body when retracted. The hollow structure of the first base body allows the second base body to nest inside it, creating a compact configuration for brake disc detection. This nesting arrangement enables the base to transition from a large extended state for tire detection to a small retracted state for brake disc detection, resolving the adaptability issue.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If bases are replaced for different detection scenes, then the adaptability is improved, but the operation complexity increases

Engineering Contradiction:
Improvedetection scene compatibilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of using separate replaceable bases for different detection scenes, the invention merges multiple base configurations into a single integrated base structure. The telescopic mechanism allows one base to perform the functions of multiple bases, eliminating the need for replacement operations and reducing operational complexity while maintaining adaptability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base is designed as a universal structure that can serve multiple detection purposes. By incorporating the telescopic mechanism, a single base can be used for both tire tread detection (when extended) and brake disc detection (when retracted), eliminating the need for scene-specific base replacements and simplifying the operational workflow.

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

3Adaptability or versatility

If bases are replaced for different detection scenes, then the adaptability is improved, but the support stability deteriorates

Engineering Contradiction:
Improvedetection scene compatibilityVSAvoidsupport stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The telescopic mechanism enables the base to dynamically adjust its configuration based on the detection scene. When extended, it provides a large stable base for tire tread detection; when retracted, it provides a compact stable base for brake disc detection. This dynamic adjustment maintains support stability across different scenes without requiring base replacement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The nesting structure ensures that when the base is retracted for brake disc detection, the second base body is securely accommodated within the first base body. This nested arrangement maintains structural integrity and support stability in the compact configuration, eliminating the instability issues associated with externally hung or replaceable bases.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If externally hung bases are used, then the adaptability is improved, but the appearance integrity deteriorates

Engineering Contradiction:
Improvedetection scene compatibilityVSAvoidappearance integrity
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The second base body is designed to nest within the hollow structure of the first base body when not in use. This nesting arrangement keeps the base components integrated and visually cohesive, eliminating the appearance issues associated with externally hung bases. The compact nested configuration maintains the aesthetic integrity of the device while preserving adaptability.

Inventive Principle:
Principle #7Nested doll (Nesting)
