Standing Workstation With Waist and Foot Support for Fatigue Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional workstations often lead to user fatigue and injury due to prolonged weight-bearing on feet, limiting productivity and causing back pain and upper body strain, especially in tasks that require static positions like cashiering.
Innovation Solution
A standing workstation comprising a table, waist rest, foot rest, and adjustable arm rests mounted on a height-adjustable post with wheels, allowing users to redistribute 60% to 80% of their body weight from feet to a larger surface area, promoting comfort and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user maintains a standing position at a conventional workstation, then back pain is reduced and upper limb control is improved, but body weight continuously loads the feet causing fatigue and injury
Solution Approach 1:
The workstation divides body weight support into multiple segments: the foot rest supports foot weight, the waist rest supports torso weight, and the arm rests support upper limb weight. This segmentation distributes the load across different body regions, preventing excessive weight concentration on the feet while maintaining standing posture benefits.
Solution Approach 2:
The invention adds vertical dimension support structures (posts with adjustable heights) that enable multiple support surfaces at different elevations. This dimensional approach allows the user's body weight to be distributed across foot rest, waist rest, and arm rests at varying heights, transforming the single-plane weight bearing into a multi-level support system.
2Object-affected harmful factors
If a cashier sits in a chair performing shifting movements, then body weight is relieved from feet, but movements become awkward and tiring with increased upper body stress
Solution Approach 1:
The workstation incorporates adjustable components (height-adjustable post, movable waist rest, movable foot rest, adjustable arm rests) that allow the user to dynamically reposition support surfaces according to movement needs. This dynamic adjustability enables spontaneous body weight shifting and movement while maintaining proper posture, eliminating the awkwardness of fixed seating arrangements.
Solution Approach 2:
The waist rest and foot rest serve multiple functions: they provide weight support, enable body positioning adjustments, and facilitate spontaneous movements. The arm rests similarly support both static working positions and dynamic movements, making the workstation universally adaptable to various task requirements while maintaining foot relief.
3Stability of the object's composition
If conventional workstations are designed for static positions, then equipment stability is maintained, but user fatigue and injury increase due to prolonged weight-bearing
Solution Approach 1:
The workstation structure segments the support function into multiple independent components (foot rest, waist rest, arm rests) that can remain stable in their positions while collectively supporting the user in dynamic ways. Each component maintains its positional stability while the system as a whole accommodates user movements and weight shifts.
Solution Approach 2:
The adjustable support surfaces enable the user to self-adjust their posture and weight distribution without external assistance. The user can independently reposition the waist rest, foot rest, and arm rests to maintain comfort and prevent fatigue during prolonged use, thereby maintaining productivity without increasing injury risk.
