Mattress display rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattress display racks require significant floor space for customer evaluation and are difficult to move from storage to display positions due to their weight, posing a risk of damage and muscle strain to sales personnel.
Innovation Solution
A mattress display rack design featuring a housing with retention rails and carriages on rollers, along with platforms that include gas springs to facilitate easy movement from a vertical storage position to a horizontal display position, allowing for efficient space utilization and safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the platform is made from metal or similar durable materials for durability, then the strength and reliability of the platform is improved, but the weight of the platform increases making it difficult for salespersons to move
Solution Approach 1:
Gas springs are installed on the platform to provide counterbalancing force that offsets the weight of the metal platform and mattress. The gas springs create an upward force that counteracts gravity, making the platform easy to lift and position without requiring salespersons to manually hoist heavy loads.
Solution Approach 2:
The manual mechanical lifting system is replaced with a gas spring-based mechanical assistance system. Instead of relying on human strength to move the heavy platform, the gas springs provide automated mechanical assistance through pneumatic pressure, reducing physical strain on salespersons.
2Reliability
If the platform is made heavy for durability, then the reliability is improved, but the ease of operation deteriorates as salespersons experience muscle strain
Solution Approach 1:
Gas springs provide counterbalancing force that makes the heavy platform easy to maneuver. The counterbalancing mechanism reduces the effective weight that salespersons must lift, allowing smooth and controlled movement of the platform between storage and display positions without muscle strain.
Solution Approach 2:
The gas springs enable the platform to assist its own movement by providing automatic mechanical assistance. When activated, the gas springs self-generate the force needed to lift and position the platform, reducing the physical effort required from salespersons and preventing muscle strain.
3Ease of operation
If mattresses are displayed in a position suitable for customer evaluation, then the ease of operation for customers is improved, but the floor space required increases significantly
Solution Approach 1:
The display rack utilizes vertical space by extending upward from the floor, allowing multiple platforms to be stacked at different heights. This vertical arrangement enables customers to access mattresses at various levels without requiring proportional increases in floor space, effectively transitioning from a horizontal to a vertical space utilization model.
Solution Approach 2:
Multiple platforms are nested vertically within the housing structure, with each platform containing a mattress. The nested arrangement allows multiple display units to occupy a compact footprint while providing individual customer access to each mattress level, maximizing space efficiency while maintaining customer accessibility.
