Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bracket attachment structures do not effectively detachably attach a bracket with a radar unit to an outer lens, lacking a stable and vibration-resistant configuration.

Innovation Solution

A bracket attachment structure that includes a bracket main body with a front surface for the radar unit and a rear surface, an extension part for attachment to a partner, and restricting and fitting recessed parts for stable engagement with the outer lens, ensuring secure attachment and resistance to movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bracket is detachably attached to an outer lens recessed part, then the radar unit can be installed and removed flexibly, but the bracket may move or shift position under vehicle vibration

Engineering Contradiction:

Improvedetachable attachmentVSAvoidpositional stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The bracket main body is nested within the recessed part of the outer lens, with the restricting part fitting into the fitting recessed part to create a nested configuration that prevents movement while allowing detachable attachment

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The restricting part and fitting recessed part act as intermediary elements between the bracket and outer lens, providing a mechanical interface that ensures stable positioning while maintaining detachability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the bracket is securely fixed to prevent movement, then positional stability is improved, but the attachment structure becomes more complex

Engineering Contradiction:

Improvepositional stabilityVSAvoidattachment structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The engaging part and restricting part are combined into a unified attachment mechanism where the restricting part protruding from the bracket main body engages with the fitting recessed part, simplifying the overall structure while ensuring stability

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided is a bracket attachment structure for detachably attaching a bracket to which a radar unit is attached to an outer lens. In the bracket attachment structure, the outer lens is attached to a lamp housing and constitutes a lamp chamber in which a lamp unit is disposed between the outer lens and the lamp housing, the outer lens includes a recessed part, the bracket includes a bracket main body disposed in the recessed part and an extension part extending from an other end side on a side opposite to one end side of the bracket main body to the outside of the recessed part and detachably fixed to an attachment partner, a restricting part is provided on a bottom surface of the recessed part, and a fitting recessed part into which the restricting part is inserted and fitted is provided in the bracket main body.
