Connector devices and connector assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector devices for exercise equipment and similar apparatuses face challenges in providing a secure, tool-free, and easily replaceable connection method that ensures proper alignment and orientation of components without requiring extensive manufacturing complexity or high costs.
Innovation Solution
A connector assembly comprising a base part with a through-hole and apertures, and a device with angled outer surfaces that self-align and self-fixate within the base part, allowing for a bolt to create a threaded connection, enabling modular and independent attachment of structural members without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connector devices are used for exercise equipment, then secure connection is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The connector device is divided into two separate components: a base part with a through-hole and a device part with a bolt-hole. This segmentation allows each component to be manufactured independently using simpler processes, reducing overall manufacturing complexity while maintaining connection security through the bolted joint.
Solution Approach 2:
The angled outer surfaces on the device are designed to self-align with the base part during insertion, automatically orienting the bolt-hole to align with the through-hole without requiring external alignment tools or complex adjustment mechanisms. This self-aligning feature reduces manufacturing complexity by eliminating the need for precision alignment features.
2Reliability
If traditional connector devices are used, then connection security is achieved, but ease of replacement deteriorates
Solution Approach 1:
By separating the connector into a base part and a removable device part connected by a bolt, the design enables easy replacement of the device portion without affecting the base structure. Users can simply remove the bolt to replace the device, maintaining secure connection when assembled while greatly improving ease of replacement.
Solution Approach 2:
The connector transitions from a static, permanent connection to a dynamic, adjustable connection that can be easily assembled and disassembled. The bolted joint allows the connection to be securely fastened during use but easily released when replacement is needed, providing both reliability and ease of repair.
3Manufacturing precision
If self-aligning angled surfaces are added to the device, then alignment precision improves, but device complexity increases
Solution Approach 1:
The device incorporates angled outer surfaces that are asymmetric in shape but simple in form. These angled surfaces provide precise self-aligning functionality during insertion while maintaining a relatively simple geometric structure that does not significantly increase manufacturing complexity.
Solution Approach 2:
The angled surfaces perform the alignment function automatically during the insertion process without requiring external alignment tools, complex adjustment mechanisms, or additional alignment features. This self-aligning capability achieves precise alignment while minimizing the increase in device complexity.

AI summary
A connector assembly comprises a base part that defines a through-hole for receiving a bolt and also defines an aperture for receiving a device having a first end that fits through the aperture in the base part and a second end that does not fit through the aperture in the base part. The first end of the device defines a bolt-hole for engaging with a bolt extending though the through-hole in the base part. The second end of the device comprises opposing outer surfaces that engage the base part and thereby prevent the device from passing completely through the aperture, and also align the bolt-hole in the device with the through-hole in the base part when the first end of the device is inserted into the aperture.
