Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face fatigue issues when maintaining continuous pressure on spray container push buttons, leading to control over fineness failures, and existing securing devices are often heavy, complex, or costly.
Innovation Solution
A lightweight, compact holding device for spray containers with a simple structure, featuring a supporting part, an adjusting part with a pillar-shaped and diving board-shaped portion, and an auxiliary part, which allows for continuous fluid release without constant operator force, reducing fatigue and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a securing device is designed to be big and heavy, then it can provide strong holding force, but it causes significant operator fatigue
Solution Approach 1:
The holding device is segmented into three functional parts: a supporting part that provides structural foundation, an adjusting part with pillar-shaped and diving board-shaped portions that enable force distribution, and an auxiliary part with interlocking protrusions. This segmentation allows each component to contribute to holding force while keeping individual parts lightweight.
Solution Approach 2:
The diving board-shaped portion acts as a mechanical intermediary that transmits and distributes force from the push button to the supporting part. This lever-like structure amplifies the operator's input force while maintaining a lightweight design, eliminating the need for heavy direct-contact securing mechanisms.
2Reliability
If a securing device is designed with complex structure, then it can provide reliable holding function, but it increases manufacturing cost
Solution Approach 1:
The holding device merges multiple functions into a single integrated structure: the supporting part provides both structural support and mounting functionality, while the adjusting part with its pillar-shaped and diving board-shaped portions simultaneously provides force distribution and mechanical advantage. This consolidation reduces the number of separate components and simplifies manufacturing.
Solution Approach 2:
The auxiliary part features self-aligning interlocking protrusions that automatically engage with corresponding recesses during assembly. This self-service mechanism ensures reliable holding function without requiring complex alignment procedures or additional fastening operations, thereby reducing manufacturing complexity and cost.
3Volume of moving object
If a securing device is designed to be compact, then it occupies minimal space, but it may reduce holding capability
Solution Approach 1:
The diving board-shaped portion extends in a direction perpendicular to the main axis of the push button, utilizing three-dimensional space efficiently. This dimensional arrangement allows the force distribution mechanism to extend outward rather than upward or downward, maintaining a compact overall profile while providing sufficient leverage for strong holding capability.
Solution Approach 2:
The pillar-shaped portion of the adjusting part acts as a structural counterbalance that provides mechanical advantage. Its vertical orientation creates a lever arm that multiplies the operator's input force, enabling strong holding capability within a compact volume by exploiting gravitational and mechanical principles rather than increasing physical size.

AI summary
A holding device is used to maintaining a push button of a spray container to be pressed to release contents without continuous press by an operator. The holding device for a spray container comprises a supporting part which is placed around the push button, an adjusting part having a pillar-shaped portion standing on the supporting part and a diving board-shaped portion connected to the pillar-shaped portion and extending over a top of the push button, on a top of the diving board-shaped portion having a recess; and an auxiliary part being pillar-shaped and standing on the supporting part, having a protrusion toward the adjusting part to be engaged with the recess.
