Solution Overview
Problem
The existing front bumper assemblies for cleaning robots have a complex rebound structure with many parts, occupying a large structural space and being high in manufacturing cost.
Innovation Solution
A simplified front bumper assembly design featuring two integrally formed elastic pieces with first and second elastic portions, which provide counterforces for front-back and lateral rebound, reducing the number of components and space usage while maintaining functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rebound structure is used in the front bumper assembly, then the bumper can provide effective collision detection and rebound function, but the structure occupies a relatively large structural space and has high manufacturing cost due to many parts
Solution Approach 1:
The patent merges the first elastic portion and second elastic portion into a single integrally formed elastic piece. This elastic piece simultaneously provides both the first counterforce (through the first elastic portion) and the second counterforce (through the second elastic portion), eliminating the need for separate rebound structures and reducing the total number of parts while maintaining collision detection functionality
Solution Approach 2:
The integrally formed elastic piece serves multiple functions: it provides both longitudinal rebound (first elastic portion) and lateral rebound (second elastic portion), acts as a structural support element, and enables collision detection. This multi-functional design reduces the overall complexity of the front bumper assembly
2Force
If a traditional rebound structure with many parts is used, then adequate rebound forces can be provided, but the manufacturing cost increases due to multiple components requiring assembly
Solution Approach 1:
The patent combines multiple elastic components into a single integrally formed elastic piece that can be manufactured as one unit. This eliminates the need for assembling multiple separate springs or elastic elements, reducing manufacturing complexity and cost while maintaining the necessary rebound forces through the integrated first and second elastic portions
Solution Approach 2:
The patent changes the structural parameters of the elastic piece by creating an integral structure with specific geometric configurations (first bent portion, spring portion, second bent portion) that provide the required mechanical properties. This allows the single component to deliver adequate rebound forces without requiring multiple parts
3Reliability
If a complex rebound structure is installed at the front of the bumper body, then collision detection is enabled, but the available structural space in the cleaning robot is reduced
Solution Approach 1:
The patent merges the rebound structure into a compact integrally formed elastic piece that attaches to the rear end of the bumper body. This compact design provides both first and second elastic portions for collision detection while occupying minimal structural space within the cleaning robot's body, unlike traditional distributed rebound structures
