Adjustable Counterbalance Lift System for Multi-User Workspaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift systems for electronic displays and workstations are inflexible and do not adequately accommodate multiple users or varying loads, leading to inefficient use in shared workspaces.
Innovation Solution
A lift mechanism with a counterbalance mechanism that adjusts to counteract the combined weight of the load and movable portion, allowing for a wide range of weights and positions, using methods like adjusting tension or angle of energy storage members to accommodate different loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed lift system is used, then the structure is simple, but it cannot accommodate multiple users or varying loads
Solution Approach 1:
The lift system incorporates adjustable components including the counterbalance mechanism that can be repositioned along the rail, and the energy storage member tension adjustment mechanism. These dynamic elements allow the system to adapt to different load weights and user requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The system allows modification of key parameters such as the tension of the energy storage member (spring or gas spring) and the position of the counterbalance mechanism. By changing these parameters, the lift system can accommodate varying loads and different user needs without requiring a completely different structure for each scenario.
2Adaptability or versatility
If an adjustable counterbalance mechanism is implemented, then adaptability to varying loads is improved, but device complexity increases
Solution Approach 1:
The system uses a counterbalance mechanism with a weight that can be adjusted along the rail to counteract the load weight. This counterweight approach provides adaptability to different loads while maintaining mechanical simplicity through the use of gravity-based balancing rather than complex active control systems.
Solution Approach 2:
The counterbalance mechanism is designed to be dynamically adjustable, allowing the counterweight position to be changed based on load requirements. This dynamic adjustment capability enables the system to adapt to varying weights while keeping the adjustment mechanism simple and manual rather than automated.
3Force
If energy storage member tension is adjusted, then lift force is optimized for different loads, but ease of operation decreases
Solution Approach 1:
The energy storage member tension is adjusted in advance before use, allowing the system to be pre-configured for the expected load. This preliminary adjustment ensures optimal lift force is available when needed, while the adjustment process itself is performed separately from the lifting operation.
Solution Approach 2:
The tension of the energy storage member is modified by changing physical parameters such as spring pre-compression or gas spring pressure. These parameter changes directly affect the lift force generated, allowing optimization for different load weights through straightforward mechanical or pneumatic adjustments.

AI summary
A lift system is designed for raising and lowering a load. The lift system can include a movable portion in sliding engagement with a fixed portion. The lift system can be configured to translate the load coupled to the movable portion relative to the fixed portion. The lift system can also include a counterbalance mechanism having an arm rotatably coupled to the fixed portion, and one or more springs coupled to the arm and the fixed portion. The arm can be operably coupled to the movable portion through a cord. As the movable portion translates, the arm can rotate to deflect the one or more springs to provide a lift force to offset the weight of the load.
