Walking Runners With One-Way Brake and Stabilization Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for enabling disabled persons with paresis or paralysis to walk upright and move in an alternating step manner are limited in their ability to facilitate longer movements without external energy sources, as they typically allow only short steps due to rigid or retractable mechanisms.
Innovation Solution
A pair of trapezoidal runners with swivel-connected vertical brackets, knee supports, and hand grips, featuring a one-way brake and stabilization rod, allowing for longer strides by utilizing double sets of wheels and flexible or rolling feet, enabling disabled individuals to perform alternating steps or travel movements up to 50-100 cm in length without external energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If rigid or retractable mechanisms are used in runners, then stability is maintained, but movement length is limited to short steps
Solution Approach 1:
The patent applies dynamics by making the runner structure movable and adjustable. The runner includes a movable support element that can be positioned in multiple locations along the runner body, allowing the step length to be dynamically adjusted. This transforms the rigid structure into a dynamic system that adapts to different movement requirements, enabling both short steps and longer travel movements without increasing overall mechanism complexity.
2Reliability
If multiple feet with flexible material are used, then protection against overturning is provided, but device complexity increases
Solution Approach 1:
The patent extracts the essential anti-overturning function from the complex multi-foot system and implements it through a simplified mechanism. Instead of using multiple feet with flexible material distributed along the runner, the invention uses a single movable support element that can be positioned to provide stability when needed. This extraction principle reduces the number of components while maintaining the protective function against overturning.
3Adaptability or versatility
If retractable supports with brackets are used, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the user to easily adjust the runner configuration through simple manual operation. The movable support element can be repositioned along the runner body without requiring complex mechanisms or significant effort. This allows the device to adapt to different user needs and movement types while maintaining ease of operation, as the user can independently adjust the configuration as needed.

AI summary
Pair of runners for walking and/or travel movement characterized by the fact that the secondary beam (1b) contains at least two sets of wheels (5), one in the rear of a runner and the second the front of a runner, while the main beam (1a) includes at least two feet (6a) made of flexible material or at least two rolling sets (6b); at least one set of wheels (5) in every runner is equipped with mechanism for locking of the wheels rotation and runners are connected by a stabilization rod (8).
