Robot Outer Cover Assembly with Protrusion-Guided Handle Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lawn mower robots face difficulties in assembling the outer cover and support portion due to the latter being covered, making it hard to recognize assembling positions and fasten the carrying handle effectively.
Innovation Solution
The design includes a prop portion with a protrusion that protrudes through the outer cover, facilitating easy recognition of assembling positions and enabling easy assembly of the handle and support portion, along with a corrugated portion for enhanced impact absorption and elastic support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the support portion is covered by the outer cover, then the appearance is improved and the structure is compact, but it becomes difficult to visually recognize assembling positions and fasten the carrying handle
Solution Approach 1:
A guide member is introduced as an intermediary component between the outer cover and support portion. The guide member protrudes from the outer cover and aligns with the support portion, serving as a visual and physical guide for assembly. This mediator allows the outer cover to remain closed (maintaining appearance) while providing clear assembly guidance through the protruding guide member.
Solution Approach 2:
The assembly guidance is moved from a two-dimensional surface recognition problem to a three-dimensional spatial alignment problem. The guide member protrudes outward from the outer cover, creating a visible and tactile reference point in space that guides the assembly operation without requiring the outer cover to be opened or transparent.
2Device complexity
If the support portion is covered by the outer cover, then the structure is compact and aesthetically pleasing, but it becomes difficult to fasten the carrying handle with the support portion
Solution Approach 1:
The guide member acts as a mediator that extends the functionality of the covered support portion. By protruding from the outer cover, it provides a accessible interface for alignment and fastening operations, allowing the carrying handle to be securely attached without exposing the entire support portion structure.
Solution Approach 2:
The critical assembly guidance function is extracted from the support portion itself and embodied in the separate guide member that protrudes from the outer cover. This allows the support portion to remain compact and covered while the extracted guide function remains accessible for assembly operations.
3Strength
If the outer cover is positioned at an upper portion of the support portion and fastened by a bolt, then the connection is secure, but it is difficult to visually recognize assembling positions
Solution Approach 1:
The guide member serves as a visual and physical intermediary that marks the assembling position. It protrudes from the outer cover at the precise location where assembly is needed, making the position easily recognizable without compromising the bolt connection strength between the outer cover and support portion.
Solution Approach 2:
The guide member can be designed with contrasting color or visual characteristics that make it easily distinguishable against the outer cover and support portion. This visual enhancement allows operators to quickly identify assembling positions without affecting the mechanical connection strength.
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
This design enhances the assembly convenience and durability by allowing easy recognition of assembling positions and providing elastic support to the outer cover, ensuring secure and efficient handling of the lawn mower robot.
Implementation Method 1
a support portion spaced apart from each other at an upper portion of the inner body and elastically supporting the outer cover in a front-rear direction and in a left-right direction with respect to the inner body
Implementation Method 2
the support portion of the rubber material may absorb a shock, while moving backwards with respect to the inner body when the outer cover collides with an obstacle
