Portable Exercise Apparatus Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable exercise apparatuses for resistance training lack a compact, cost-effective, and easily manufacturable design that effectively secures the device to the user's body while allowing for adjustable resistance levels and comfort during upper torso workouts.
Innovation Solution
A portable exercise apparatus featuring an injection moulded ABS chest plate with adjustable nylon webbing straps, a latching mechanism with a pin and cord, and a locking mechanism that secures the straps in place, along with color-coded resistance bands and hand grips for varying resistance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a latching mechanism with pin and cord is used to secure straps, then the reliability of securing the device to the user's body is improved, but the device complexity increases
Solution Approach 1:
The latching mechanism is divided into separate components: a first latch portion on the first strap portion, a second latch portion on the second strap portion, and a pin that interlocks them. This segmentation allows each component to be simple in design while collectively providing reliable securing through the interlocking arrangement of multiple parts.
2Ease of manufacture
If injection moulded ABS chest plate is used, then the ease of manufacture is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The chest plate is manufactured using injection moulding of ABS material, which allows for efficient mass production through parameter optimization in the moulding process. This manufacturing method changes the production parameters to achieve both ease of manufacture and acceptable precision for the structural components.
3Adaptability or versatility
If adjustable nylon webbing straps are used, then the adaptability to different users is improved, but the device complexity increases
Solution Approach 1:
The nylon webbing straps are designed to be adjustable, allowing dynamic adaptation to different user sizes and preferences. The straps can be modified in length and configuration to suit various users, providing versatility without requiring multiple complete strap assemblies.
