Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional office chairs do not provide a means for users to engage in exercise while seated.
Innovation Solution
A multifunctional chair design incorporating a telescopic structure, pedal assemblies with elastic resistance, and adjustable armrests, allowing users to perform muscle training exercises by operating the pedals and telescopic mechanism, which can be easily converted back to a standard office chair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional office chair is used, then the chair provides basic seating functionality, but it does not allow users to engage in exercise
Solution Approach 1:
The patent combines the exercise function with the office chair by integrating pedal assemblies into the chair's base structure. The pedal assemblies are connected to the supporting body through telescopic structures, merging the exercise equipment functionality with the seating furniture into a single unified system that serves both purposes.
Solution Approach 2:
The office chair is designed to serve multiple functions: it provides basic seating support while also enabling exercise activities through the integrated pedal assemblies. The telescopic structure allows the same chair to accommodate both stationary seating and active exercise modes, making the furniture piece universal in its utility.
2Adaptability or versatility
If exercise functions are added to the office chair, then users can engage in exercise, but the chair structure becomes more complex
Solution Approach 1:
The exercise function is segmented into separate pedal assemblies that are independently connected to the chair's supporting body. Each pedal assembly operates as a distinct module with its own movable rod, fixing rod, and elastic resistance member, allowing the exercise functionality to be added without completely redesigning the chair structure.
Solution Approach 2:
The telescopic structure incorporates movable components that can extend and retract. The movable rods in the pedal assemblies can move relative to the fixing rods, and the telescopic structure itself can extend outward or retract toward the supporting body, providing dynamic adaptability while maintaining a compact form when not in use.
3Adaptability or versatility
If the telescopic structure is extended for exercise, then exercise space is provided, but the chair occupies more space
Solution Approach 1:
The telescopic structure is designed to be dynamically adjustable, extending outward to provide exercise space when needed and retracting toward the supporting body when not in use. This dynamic configuration allows the chair to transition between a compact storage state and an expanded exercise state, minimizing the occupied area during normal office use.
Solution Approach 2:
The telescopic structure employs a nested configuration where the movable components can be stored within or alongside the fixed structure. When retracted, the telescopic elements nest back into the supporting body, and the pedal assemblies can be positioned to minimize their spatial footprint, allowing the exercise equipment to be contained within the overall chair envelope when not actively used.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to engage in exercise while seated, providing a convenient and space-efficient way to incorporate physical activity into daily work routines without compromising the chair's stability or functionality as an office chair.
Implementation Method 1
The elastic resistance member has two ends respectively fixed to the supporting body and the fixing rod. The operation portion is configured to be operated, so that the movable rod and the fixing rod are configured to rotate relative to the supporting body, and the elastic resistance member is configured to provide an elastic resistance.

AI summary
A multifunctional chair is provided. The multifunctional chair includes a supporting body, a telescopic structure, a seat body, and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operation portion, and an elastic resistance member. The telescopic structure is connected to the supporting body and configured to be operated to telescopically move relative to the supporting body. One end of the fixing rod is fixed to the supporting body. The movable rod is movably connected to the fixing rod. The operation portion is arranged at an end of the movable rod away from the fixing rod. Two ends of the elastic resistance member are respectively connected to the supporting body and the fixing rod. A user can push against the operation portion to rotate the movable rod and the fixing rod toward the ground, and the elastic resistance member provides an elastic resistance.
