Solution Overview
Problem
Existing moving robots require a large number of impact sensors to sense impacts in multiple directions, which increases the size and cost of the robot, and fails to effectively restrain bumper movement upon impact.
Innovation Solution
The robot employs impact sensors placed at an angle with bent pressure parts to sense impacts in multiple directions, and includes a movement guide part with kite-shaped guide holes to restrain bumper movement, allowing for effective impact sensing and position recovery.

Engineering Contradiction Analysis
1Measurement precision
If impact sensors are increased in number to sense impact in multiple directions, then impact sensing capability is improved, but moving robot structure size and cost increase
Solution Approach 1:
Each impact sensor is designed to perform multiple functions by sensing impacts from different directions through strategic angular placement. The pressure parts are configured to transmit forces from multiple directions to the same sensor, allowing one sensor to detect impacts from various directions rather than requiring separate sensors for each direction.
Solution Approach 2:
The impact sensors are placed at angles rather than aligned with cardinal directions, adding a dimensional aspect to impact detection. This angular placement allows sensors to detect impacts from multiple directions simultaneously by resolving force vectors, effectively using spatial arrangement to achieve multi-directional sensing with fewer sensors.
2Strength
If bumper is made more robust to withstand impact, then impact resistance is improved, but movement restraint capability deteriorates
Solution Approach 1:
The bumper system is divided into functional segments: the bumper itself for absorbing impact forces, and separate movement guide parts with protruding guides and guide holes for restraining movement. This segmentation allows the bumper to be optimized for strength while the guide structure handles movement restraint, preventing the need to compromise one function for the other.
Solution Approach 2:
The movement guide part acts as an intermediary between the bumper and the robot body. The protruding guides and guide holes create a mechanical constraint system that restrains bumper movement without requiring the bumper itself to be less robust. This intermediary structure mediates between impact absorption and movement control functions.
