Adjustable Bench with Removable Stand for Decline Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable benches often cannot be positioned in decline use positions due to the interference from stands or support posts, limiting their versatility and usability in various exercise settings.
Innovation Solution
An adjustable bench design featuring a removably secured stand that allows the bench to be positioned vertically for storage, reducing floor space, and includes a telescoping support and adjustable mechanism enabling the back support to be positioned in decline, level, or incline use positions without interference from the stand, along with a sliding seat adjustment mechanism for enhanced adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stand or support post is permanently attached to the bench, then the bench is stable and can be stored vertically, but the stand interferes with positioning the bench in decline use positions
Solution Approach 1:
The stand is designed to be removably coupled to the back support rather than permanently fixed. This dynamic coupling allows the stand to be attached when vertical storage is needed and detached when decline positioning is required, enabling the system to adapt between different operational states without permanent structural compromises.
Solution Approach 2:
The stand is separated from the main bench frame as an independent, detachable component. This segmentation allows the stand to function independently when attached for vertical storage, and be removed when not needed, eliminating interference with decline positioning while maintaining stability when required.
2Object-affected harmful factors
If the stand is permanently attached to support the back cushion, then the back cushion is protected from damage, but the bench cannot be positioned in decline use positions
Solution Approach 1:
The removable coupling mechanism allows the stand to be dynamically attached or detached based on operational needs. When attached, it protects the back cushion during vertical storage; when detached, it allows full range of motion for decline, level, and incline positions without structural interference.
3Ease of manufacture
If the bench is designed with fixed support structures, then manufacturing is simple, but the bench lacks adjustability for different use positions
Solution Approach 1:
The back support is designed with pivotable joints and removable stand coupling that allow multiple positions while maintaining relatively simple manufacturing. The pivotable connection between back support and seat support, along with the removable stand attachment, provides adjustability without requiring complex mechanisms.
Solution Approach 2:
The bench is divided into separable components (frame, back support, stand) with standardized connection points. This segmentation allows for simple manufacturing of individual parts while enabling versatility through their configurable assembly and relative positioning.
4Volume of moving object
If the stand extends beyond the back cushion length, then the bench can be stored vertically, but the stand interferes with decline positioning
Solution Approach 1:
The removable coupling allows the stand's extended length to be utilized during vertical storage while eliminating interference during decline positioning. The dynamic attachment/detachment resolves the spatial conflict by allowing the stand to occupy extended space only when needed for vertical storage.

Function Achieved in This Case
The design enhances the versatility of the bench by allowing it to be used in multiple positions, including decline, while protecting the back cushion from damage and improving user accessibility and comfort through adjustable features.
