Holding Device Groove Element Positive Locking Mechanism

Solution Overview

Problem

Existing holding devices for attaching add-on components to handlebar-controlled vehicles, such as bicycles, face issues with large installation space requirements, high manufacturing costs, and operational complexity due to their design.

Innovation Solution

A holding device with a compact design featuring a fastening device and a connecting device that includes a first adapter unit with a retaining device having a groove element for positive locking, allowing for secure and intuitive connection of add-on components like smartphones or water bottle holders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a bayonet lock with a large diameter mounting plate is used, then the connection is secure, but the installation space requirement increases and manufacturing costs increase

Engineering Contradiction:

Improveconnection securityVSAvoidmounting plate diameter

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The mounting plate is segmented into a first adapter unit with a retaining device and a second adapter unit with a receptacle. The retaining device includes a groove element that engages with a corresponding element in the receptacle, creating a positive locking connection. This segmentation allows each component to be smaller while maintaining overall connection security through the interlocking groove-element mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bayonet lock mechanism is extracted and replaced with a groove element-based positive locking system. The groove element is integrated into the first adapter unit, eliminating the need for a large diameter mounting plate while providing secure connection through the groove-receptacle engagement.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If a bayonet lock with a large diameter mounting plate is used, then the connection is secure, but the manufacturing cost increases

Engineering Contradiction:
