Lid Support Structure with Separate Operation Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lid support structure for saddle-type vehicles, such as motorcycles, lacks operability in determining the correct position to push the lid to release the locking portion, leading to inferior attachability and detachability without compromising the design aesthetics.
Innovation Solution
The lid support structure incorporates an operation surface positioned separately from the lid surface, utilizing a vehicle body cover with angled first and second openings to create a space where the operation surface can be easily accessed, allowing for superior attachability and detachability without design deterioration, employing a snap fit mechanism for engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mark is added to indicate the position where the lid should be pushed, then operability is improved, but the design of the lid and surrounding area is deteriorated
Solution Approach 1:
The lid is divided into two distinct surfaces: a lid surface for closing the first opening and an operation surface for disengagement through the second opening. This segmentation allows the operation surface to be positioned separately, providing clear operational indication without adding marks that would deteriorate the design of the lid and surrounding area.
2Ease of operation
If the operation surface is positioned separately from the lid surface, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The operation surface and lid surface are merged into a single integrated lid structure. This integration allows the operation surface to be positioned separately for improved ease of operation while avoiding the complexity of separate components, fasteners, or additional mechanisms.
3Productivity
If the lid is made easily detachable by pushing one end portion, then productivity is improved, but reliability of engagement may be worsened
Solution Approach 1:
The lid support structure employs a dynamic snap fit mechanism that transitions between engaged and disengaged states. The locking portion moves between locked and unlocked positions in response to pushing the operation surface, providing easy detachability while maintaining reliable engagement through the snap fit's inherent mechanical locking action.
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 operability of the lid by allowing easy detachment and attachment with minimal force, maintaining the aesthetic integrity of the vehicle body cover and lid surface, leveraging the angled surfaces and snap fit mechanism for efficient engagement and disengagement.
Implementation Method 1
a snap fit configured to be engaged with the vehicle body cover and directed to be disengaged from the vehicle body cover by pushing the operation surface towards an inner side of the vehicle body cover
Implementation Method 2
a locking portion configured to lock the snap fit to the vehicle body cover in a state where the snap fit is engaged with the vehicle body cover
