Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for packaging straw blocks for thermal insulation are costly, inefficient, and lack ergonomic design, making it difficult to transport and supply straw blocks from local production sites to construction sites while maintaining stability and reducing overall costs.
Innovation Solution
A palletizer system comprising a frame, cradle, and compression and tying mechanisms that allow for the efficient stacking, compression, and binding of straw blocks onto handling pallets, enabling high-height, stable pallets that maximize truck volume and reduce production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If straw blocks are packaged manually or with simple equipment, then implementation costs are reduced, but packaging efficiency and productivity are insufficient
Solution Approach 1:
The packaging process is divided into distinct functional modules: the cradle for positioning, compression means for compacting straw blocks, tying means for securing, and tilting mechanism for palletization. Each module performs a specific function, allowing independent optimization and maintenance while achieving high overall productivity at reasonable cost
Solution Approach 2:
The system is designed to be operated by a single worker who loads straw blocks onto the cradle, and the machine automatically performs compression, tying, and palletization functions. The equipment serves itself by integrating multiple functions into one cohesive system that requires minimal external intervention
2Productivity
If existing palletizing equipment is used, then packaging capability is achieved, but overall operating costs and implementation costs are excessive
Solution Approach 1:
The cradle serves multiple functions: it positions straw blocks during loading, supports them during compression, holds them during tying, and facilitates palletization through tilting. The compression means and tying means are integrated into the same structural framework, allowing one piece of equipment to perform what would traditionally require multiple separate machines
Solution Approach 2:
The invention merges the cradle, compression system, tying system, and tilting mechanism into a single integrated palletizing machine. This consolidation eliminates the need for separate equipment for each function, reducing implementation costs while maintaining high packaging capability
3Volume of moving object
If straw blocks are stacked to maximize truck volume, then transport efficiency is improved, but pallet stability is compromised
Solution Approach 1:
The compression means compact straw blocks before they are stacked on the pallet, removing air gaps and creating a dense, stable foundation. The tying means then secures the compressed blocks together, preventing shifting during transport. These preliminary actions ensure that even high stacks remain stable throughout the journey
Solution Approach 2:
The compression process changes the physical parameters of the straw blocks by reducing their volume and increasing their density. This parameter change transforms loose, unstable straw into compact, stable units that can be safely stacked to maximum height while maintaining pallet stability during transport
4Volume of moving object
If high-height pallets are created to optimize transport, then truck volume is maximized, but loading difficulty and ergonomic issues increase
Solution Approach 1:
The cradle can be tilted between a horizontal loading position and a vertical transport position. During loading, the cradle remains horizontal, allowing workers to easily place straw blocks at waist height. After loading, the cradle tilts vertically to create a high stack on the pallet. This dimensional change allows the system to achieve both ergonomic loading and maximum transport volume

Function Achieved in This Case
The system enables a single operator to palletize up to 4 tons of material per day, optimizing truck space and reducing overall costs by providing a robust, economical solution for transporting and supplying straw blocks.
Implementation Method 1
the cradle being mounted at least rotatably on the frame between a lying loading position intended to allow the stacking of straw blocks on the platform against a pallet carried by the support base, and a raised position in which the platform extends vertically, and in which the support base is intended to allow the removal of a pallet supporting straw blocks
Implementation Method 2
means for compressing straw blocks stacked on the platform against a pallet in the lying position of the cradle
Implementation Method 3
means for tying straw blocks to a pallet on which they are compressed in the lying position of the cradle
