Modular Wearable Robot Controller with Customizable Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable robots with fixed controllers struggle to provide a customized grip for users, leading to potential malfunctions due to inconsistent user interactions.
Innovation Solution
A controller design featuring a head part with a display unit and button unit, and a body part that can be joined in various forms through projection and recessed portions with uneven surfaces, allowing for customizable fitting to each user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the controller is fixed to the crutch in a single form, then the structure is simple, but it is difficult to provide a grip optimized for each user and may cause malfunction
Solution Approach 1:
The controller is divided into a head part and a body part that can be relatively moved with respect to each other. The head part includes a display unit and button unit, while the body part includes operation portions with different shapes. This segmentation allows users to select and fix the head part at different positions on the body part, providing customized grip options without requiring complete redesign of the entire controller structure.
Solution Approach 2:
The controller transitions from a fixed single-form structure to a dynamic multi-position structure. The head part can be fixed at various positions on the body part according to user preferences, and the operation portions have different shapes that can be selected based on user needs. This dynamic configurability enables customization while maintaining a relatively simple overall structure through modular design.
2Reliability
If the controller is fixed to the crutch in a single form, then manufacturing is easier, but it may cause malfunction depending on the user
Solution Approach 1:
The body part is designed as a universal base structure that can accommodate multiple head part configurations. The operation portions include different shaped grips (e.g., first operation portion with one shape, second operation portion with another shape) that can be selectively used. This universal design allows a single controller body to serve multiple user needs, improving reliability without requiring separate manufacturing processes for each configuration.
Solution Approach 2:
The controller allows changes in geometric parameters through the selection of different operation portion shapes and head part positions. By varying the shape parameters of operation portions and the positional parameters of the head part, the controller can be adapted to different user preferences while maintaining the same basic structure, thus improving reliability without complicating manufacturing.
3Ease of operation
If the controller allows various fixed forms, then user grip is improved, but the structure becomes more complex
Solution Approach 1:
The controller is segmented into independently configurable components: the head part (display and buttons) and the body part (operation portions). Users can fix the head part at different positions on the body part and select from different shaped operation portions, enabling customized grip and operation ease without requiring complex integrated designs.
Solution Approach 2:
The controller provides dynamic configurability where the head part can be positioned at multiple locations on the body part, and different operation portions can be selected based on user preference. This dynamic adaptation improves ease of operation while maintaining structural simplicity through modular, reconfigurable design rather than fixed complex structures.

AI summary
A controller includes: a head part including a display unit providing information and images and a button unit having operation buttons; and a body part joined to the head part, where the display unit includes a projection portion engaged with the body part, the body part includes a recessed portion into which the projection portion is inserted, a first uneven portion is provided on an outer circumferential surface of the projection portion, a second uneven portion having a shape corresponding to that of the first uneven portion is provided on an inner circumferential surface of the recessed portion, and at least one of the first uneven portion or the second uneven portion includes a plurality of uneven portions.
