Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery vehicles with a single cargo volume face challenges in maintaining optimal temperature conditions for diverse merchandise, suffer from thermal inefficiencies, and have suboptimal loading and unloading processes, particularly with lateral access doors and unleveled floors, which hinder efficient use of cargo space.
Innovation Solution
A modular climate-controlled trailer with multiple, individually managed sub-cargo volumes, vertically movable floor portions, and adjustable partition panels that allow rearward loading and insulation, along with a system for optimizing energy management and traceability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cargo volume is used in delivery vehicles, then the structure is simple and easy to manufacture, but it cannot maintain different temperature conditions for diverse merchandise and suffers from thermal inefficiencies
Solution Approach 1:
The cargo volume is divided into multiple independently controllable climate zones separated by insulated partition walls. Each zone can maintain different temperature conditions suitable for different types of merchandise, resolving the contradiction between temperature adaptability and structural complexity through functional segmentation.
Solution Approach 2:
Different regions of the cargo volume are equipped with localized temperature control systems and insulation properties tailored to specific merchandise requirements. This allows each zone to have optimized thermal characteristics without requiring complete redesign of the entire cargo structure.
2Ease of operation
If a single cargo volume is opened to access merchandise, then access is simplified, but integral temperature variations occur causing energy inefficiency and thermal damage to merchandise
Solution Approach 1:
The cargo volume is segmented into multiple climate zones with individual access points. Merchandise can be accessed in one zone without opening doors to other zones, preventing thermal exchange and energy loss in unaffected zones while maintaining ease of operation through localized access.
Solution Approach 2:
Insulated partition walls with sealed doors act as intermediaries between climate zones. These partitions allow controlled access to specific zones while maintaining thermal isolation, enabling merchandise retrieval without compromising the thermal integrity of the entire cargo volume.
3Ease of operation
If lateral access doors are used in delivery vehicles, then side access is provided, but they prevent standard rearward loading from dock with forklift and pallets
Solution Approach 1:
The partition walls are designed as movable structures that can be reconfigured or removed to create open loading pathways. This dynamic adaptability allows the cargo volume to accommodate different loading methods (rearward dock loading with forklifts or lateral loading) depending on operational requirements, resolving the contradiction between side access and loading efficiency.
4Volume of stationary object
If large cargo volume is used, then storage capacity is increased, but it becomes challenging to maintain constant temperature over vertical volume with higher areas being warmer
Solution Approach 1:
The large cargo volume is divided into multiple smaller climate zones with independent temperature control systems. This segmentation allows each zone to maintain uniform temperature distribution, preventing thermal gradients that would occur in a single large volume while preserving total storage capacity.
Solution Approach 2:
Each zone within the cargo volume is equipped with localized heating and cooling systems tailored to its specific thermal requirements. This local quality approach ensures uniform temperature distribution throughout each zone while accommodating the overall large volume through distributed thermal management.
5Device complexity
If merchandise are loaded in first-in-first-out order in single cargo volume, then storage management is simplified, but last-loaded merchandise becomes hard to access requiring unloading of previously loaded items
Solution Approach 1:
The cargo volume is segmented into multiple accessible zones, allowing different loading strategies in different zones. Some zones can implement FIFO (first-in-first-out) management while others enable direct access to recently loaded items, reducing the time penalty associated with accessing rear-loaded merchandise without complicating overall management.
