Treadmill Rack with Adjustable Inclination for Secure Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treadmills lack a supporting rack for phones or tablets, leading to user discomfort and risk of device damage due to the need to hold devices during use, which can result in soreness and accidental drops.
Innovation Solution
A treadmill rack with a mounting frame, adjusting board, and supporting board that allows for adjustable inclination and secure mounting on the treadmill armrest, featuring anti-skid layers and straps for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users hold phones or tablets in hand during treadmill exercise, then they can watch videos, but their arms become sore and devices may fall and be damaged
Solution Approach 1:
The patent extracts the device-holding function from the user's hands and transfers it to a dedicated rack structure. The rack includes a receiving cavity with a supporting board that can hold phones or tablets, freeing the user's hands and eliminating the risk of accidental drops while maintaining video watching capability during exercise
Solution Approach 2:
The rack is divided into functional segments: a mounting frame for attachment to the treadmill, an adjusting board for angle adjustment, and a supporting board with positioning posts for secure device placement. This segmentation allows each component to perform its specific function optimally while working together as a complete system
2Reliability
If a fixed supporting structure is provided, then device support is stable, but adaptability to different devices and user preferences is limited
Solution Approach 1:
The patent implements dynamic adjustability through the adjusting board connected via a hinge to the mounting frame. The adjusting board can be rotated to different angles and locked in position using an engaging member with a hook that engages with a latching flute on the first beam. This allows the rack to adapt to different user preferences and device sizes while maintaining stable support when locked
Solution Approach 2:
The rack allows changing the inclination angle parameter of the supporting board to accommodate different viewing preferences and device orientations. The positioning post can be moved between different positioning holes to adjust the exact position and angle, providing versatility while maintaining stability through the locking mechanism
3Adaptability or versatility
If the rack structure is made complex to provide multiple adjustment functions, then adaptability improves, but device complexity increases
Solution Approach 1:
The rack is segmented into modular components: mounting frame, adjusting board, supporting board, and engagement mechanisms. Each segment performs a specific function and can be independently manufactured and assembled. The positioning post with multiple positioning holes provides adjustment capability through a simple mechanical indexing system rather than complex continuous adjustment mechanisms
Solution Approach 2:
Instead of using a complex mechanism to continuously adjust the angle, the patent inverts the approach by providing discrete angular positions through the hinge and latching mechanism. The engaging member with hook and latching flute provides a simple binary state (engaged/not engaged) that locks the adjusting board at desired angles, reducing complexity while maintaining adaptability
